User Guide for iWalk Cornwall guided walks app
The iWalk app uses the GPS receiver on your device to locate your position in order to navigate the walk route. All iPhone and 3g-enabled iPads come with a built in GPS receiver. However, to use the app with a wifi-only iPad, you'll need an external GPS receiver. These can be purchased as accessories, for example on Amazon
A phone or tablet running Android 4 or above. You may experience some performance issues in Android 5.0 - these are due performance bugs and memory leaks in Android 5.0 itself; upgrading to 5.1 or above may address them.
Your device will need a GPS receiver to provide the apps with your current location. If your device doesn’t have one built-in, there are external GPS receivers available that connect via Bluetooth (click here to see those available on Amazon).
It's unlikely your phone/tablet is waterproof, so we strongly recommend buying a waterproof case in case the heavens open. The Beachbuoy waterproof bags are extremely durable and recommended.
The battery life on different phones/tablets varies, but we recommend purchasing an external battery just in case your device runs out of battery half-way around a walk.

Press the "Back" button in the top-left corner to return to the Home page.
Select "Walks shop" from the Home page to view walks which are available. Walks are listed by category - tapping a category name displays the names of walks in that category. Scroll through the list by dragging your finger up/down or search the walks by tapping the "Search walks" box and typing the name of the walk you want to do. Tap on the name of a walk to view details about it and the option to purchase it.
Press "Map of walks" for a map of Cornwall showing the locations of all our walks. The walks are shown as colour-code dots where the colour indicates the grade (difficulty) of the walk. Tap on a dot to display a popup box with a summary of the walk. Tap the popup box to open the details page for that walk or press X to close the popup box. Tick "Show routes" in the top-right to show an outline of the walk route for each walk. Press "Back" to return to the Walks shop page.
In order to use a walk for navigation, you'll need to purchase it. We've priced the walks as low we could with Apple's pricing tiers at £1.99. To purchase a walk, go to the "Walks shop" list and select a walk, then click "Purchase", then follow the prompts. Once purchased, the walk will be downloaded and made available for use in the "My walks" list.
In order to use the app to navigate a walk route, you'll first need to purchase the walk. Once purchased, it will be listed in "My walks"; selecting it from here by tapping its name will put the app in navigation mode for this walk.
To delete a walk from the device, press&hold or swipe-to-the-right on the walk in this list, then press the "Delete" button. Deleted walks can be restored at any time by pressing the "Restore purchases" button on the home page.
Important: The first time you enter navigation mode, you will be asked if you wish to allow the app access to your location. You must answer "OK" to enable the app to navigate. If you tapped "Don't Allow" by accident, go to the Settings app, select Privacy, then Location and turn on location services for this app.
You may also be shown a Calibration screen to calibrate the compass; follow the on-screen instructions in order to dismiss this. The app uses you device's compass to show you which way you are facing on the Map page.
If you are using Android 6.0 or above, the first time you enter navigation mode, you will be asked if you wish to allow permission for the app access to your location. You must answer "Allow" to enable the app to navigate. If you accidentally press "Deny", the best thing to do is to exit the walk and start it again - this will cause it to re-request location permission, popping up the authorisation box again.
After pressing "Deny" the first time, the second time the popup box is displayed, there's also a checkbox that says "Never Ask Again". If you accidentally check this and then press "Deny", the app is never allowed to ask for location permission again, so will be unable to track your progress. To remedy this, you must do the following: start the Settings app, go to Apps -> iWalk Cornwall -> Permissions, and ensure the Location permission switch is on.
To exit navigation mode, go to the "Summary" or "Options" page and select "Exit walk". If you do this while navigating a walk, route tracking will be aborted; you will be asked to confirm you wish to do this.
The buttons on the bottom of the page will now be different: "Summary", "Map", "Directions" allow you to switch between the main navigation pages. The "...". button shows/hides a second-level menu with additional options:
- Camera - switches to the camera so you can take a photo which will be stored in the Photos Camera Roll album (iOS) / the Gallery (Android)
- Pause GPS - temporarily pauses location tracking. Enable this if you're stopping during the walk to have a picnic or a swim - it will save battery power. Press it again to re-enable tracking before you resume the walk.
- Help - shows this Help page
- Options - shows the Options page
Before the walk is started, the "Summary" page show details of parking for the walk. Pressing the "Driving directions" button will give you driving directions to the parking location for the walk. The postcode and lat/lon are also shown if you want to use an in-car satnav.
Before starting to walk, make sure that the app is running, the correct walk is selected for navigation and that your device's GPS receiver has a fix (if NO GPS or SEEKING GPS is displayed, see the Troubleshooting section). This is important as the app tracks which directions you’ve visited in order to know which direction to display next. In particular it needs to know you've passed the first one to know that you’ve started the walk. We’ve tried to place the first direction so it's fairly difficult to miss.
If you forget, and walk past one or more direction points before noticed you aren't getting any new directions, rather than walking all the way back to the start, you can go to the "Directions" page and press the arrow button to the right of the last direction you passed to begin navigating from this point.
Similarly, if you get a short way round the walk and find you left your lunch in the car, when you get back to the start, you can also use the button next to Direction 1 to restart the directions from the beginning rather than having to remember where you left the rest of your family.
The "Directions" page has the current direction highlighted with the previous and upcoming directions also shown so you can both check you’ve completed the last direction and can look ahead to what's coming next.
On the "Map" page, the current direction is shown in a slide-out overlay which will automatically slide away after a minute. Click on the arrow on the right of the overlay to slide it away earlier, or back out to have another look at the direction.
The map is oriented with North at the top. If you hold your phone/tablet upright (portrait) and directly facing you, the orientation of position marker on the map will reflect the direction you are facing. There is a legend for the map in the online help within the app.
It you wander a significant distance off the route, the app will warn you, to save you discovering 2 miles down a path that it was the wrong one. If you get this warning and you are not expecting it, then check the map to make sure you are on the path that you think you are on.
On some of the walks there are locations of interest off the walk route that are mentioned in the directions or in the accompanying information as a possible diversion. In these cases the app should cope with you leaving the route to explore without warning that you are off route, provided you return to the route where you departed (often at a waymark or fork in the path).
If you want to take a diversion not covered by the directions, you can dismiss the warning in the app and it will not warn you again (unless you rejoin the route and leave it a second time). Provided you return to the route at the point where you left it, your diversion should have no effect on the app tracking your progress around the route of the walk.
However, if you wander off the route, miss direction points along the route and rejoin it further round, the app won't immediately (though will eventually) figure out that you are intending to follow the route from the new location and not intending to return to where you departed it. You can tell it that you want to resume navigation from the new location by finding the last direction point before your new location and choosing to navigate from here by clicking the arrow on the right.
Once you have started the walk, the "Summary" page shows you the walk distance, how far you have travelled, and how much further you have to walk. Also, based on your average walking speed for the most recent segment of the walk, the time remaining is estimated.
There are four main pages when the app is set in navigation mode for a particular walks. They can be reached using the buttons at the bottom of the page. The purpose of each page is described below:
When the walk is first selected, it will display the Summary page. The page shows a summary of walk information before, during and after the walk.
Before the walk
Before you've started the walk, this page will show an overview of the walk such as distance, steepness grade, start location and parking details. This is useful as a checklist before you set out, so you can prepare accordingly.
Pressing the "Show driving directions" button will use the built-in navigation app on your device to give you driving directions to the parking location for the walk from your current location.
Pressing the "Start simulation" button will run a simulation of the walk route at an accelerated speed, so you can preview the walk and the app behaviour during the walk. Once started, simulation controls will appear in place of the start button which allow you to pause/resume/stop the simulation and change the speed. Note that any changes made to settings during simulation mode will not be saved once the simulation ends.
During the walk
Once you've started the walk, this page will display progress information and the current direction instructions.
The following details are displayed during the walk:
- Total distance - the length of the entire walk route.
- Distance remaining - how far you've got left to go.
- Distance to next direction - how far until you reach the next instruction.
- Current speed - speed at present as determined by your device's GPS receiver.
- Average speed - average walking speed over the last segment of the walk. This excludes any zero speeds while you are stopped.
- Time since start - time elapsed since the walk was started.
- Estimated time remaining - predicted time until you finish the walk, based on the current average speed.
After the walk
On completing the walk, a final summary will be displayed showing the total distance you walked, the total time you took to complete the walk and your average speed based on this.
The "Restart walk" button will reset the walk ready to start again. Note: this will clear the final summary statistics.
If you enjoyed the walk and our app, please consider using the "Review the app" button to leave us a review in the App Store.
A map of the route. This is the main page you'll typically want to be using as you go around the walk. When your GPS receiver is switched on, the map page will show you where you are. As you follow the route, the next direction will automatically pop out over the top of the map. You can slide it away with the arrow on the right. The "Autoshow" toggle sets the "Autoshow next direction" setting.
When you reach the location of the start of the walk, if the "Autoshow next direction" box is ticked in the Settings page and your GPS receiver is turned on so the app is tracking you, the Map page will automatically be displayed and the first direction will be displayed in a popout over the map.
A list of all directions around the walk - handy if you want to see what's coming up next and check you've definitely passed the last one. When your GPS receiver is switched on, this will automatically higlight and scroll to the direction relevant to your current location.
The button with the navigation arrow at the top-right of each direction allows you to start navigating directions from this point. Useful if you forgot to switch your phone/tablet on! Upon pressing it and confirming this, direction information will be displayed from this point onwards.
The following options are available:
- Exit walk - Exits navigation mode and returns to the My walks page. If you select this while navigating a walk, route navigation will be aborted; you will be asked to confirm you wish to do this.
- Restart current walk - (only shown once a walk has been started) restarts directions from the start of the walk. Useful if something went wrong during navigating the walk or if you left your sandwiches in the car!
- Settings - displays the settings page (see below).
Exit app - closes the iWalk app. If you select this while navigating a walk, route navigation will be aborted; you will be asked to confirm you wish to do this.
This page allows you to customise settings for the app. Your choices will be remembered and restored next time you run the app. Note that if you have several iWalk apps installed, these settings are not shared and are stored individually for each app. The following settings can be turned on or off:
- Play sound on alerts - An audio alert will be used to notify you of important events such as a new direction to follow or if you've made a wrong turn and gone off route.
- Vibrate on alerts - Your iPhone will vibrate when the events mentioned above occur. This will only work iPhones as iPads don't have a vibration mechanism.
- Use compass - Whether to use the built-in compass to show the direction you are facing. You may want to disable this if the direction shown is wrong due to the device orientation or because the iOS compass calibration is annoying.
- Autoscroll map - The map page will automatically scroll to follow your position as your progress around the walk.
- Autoshow next direction - Upon reaching the location of a new direction, the direction text will automatically pop out over the map. If another page is currently being displayed, the map page will be automatically displayed.
- Show POIs with directions - Show information about Points of Interest below the relevant direction text. This can be turned off to shorten the Directions page.
- Units - The units of measurement to use for distances: either Statute (Miles) or Metric (Kilometres).
Here are some tips to maximise the lifetime of your battery:
- Switch off WiFi and Bluetooth before setting out on the walk as these use lots of battery power. In iOS you can do this by swiping 1 finger upwards from the bottom of the screen to show the toolbar.
- During the walk, switch the screen off by pressing the power button during long stretches between directions. The iWalk app will continue to run in the background, even when your screen is turned off, so will still beep/vibrate when there's a new direction to follow.
- Dim your screen as much as possible since this is the main drain on the battery, although for viewing outside you'll need it brighter than for inside. Again, in iOS you can do this by swiping 1 finger upwards from the bottom of the screen to show the toolbar.
- Switch off WiFi and Bluetooth before setting out on the walk as these use lots of battery power.
- During the walk, switch the screen off (usually by pressing the power button) during long stretches between directions. The iWalk app will continue to run in the background, even when your screen is turned off, so will still beep/vibrate when there's a new direction to follow. You can use a free screen lock disabling app during the walk so you don't have to unlock your screen each time you press the power button.
- Dim your screen as much as possible since this is the main drain on the battery, although for viewing outside you'll need it brighter than for inside.
If the lifetime of your phone battery has substantially degraded since you first had the phone, you can get replacement batteries for a few quid on ebay (I replaced mine for £3 including postage). Often the replacement batteries have a longer lifetime than the original one did when it was new because technology has moved on. You'll need the exact phone model to make sure you get the right battery. Replacing it should simply be a matter of taking the back off your phone and pulling the old one out.
- If you stop for a swim or a picnic during the walk, use the "Pause GPS" button to pause location tracking. This will temporarily stop tracking your position via GPS, which will save battery power. It can be found by pressing the extended menu button "...". But don't forget to press it again to re-enable location tracking before you resume the walk!
- The app will monitor how fast your battery is draining during the walk and if it looks like it's going to run out before you finish the walk, it will offer you some options to conserve battery power.
If this happens and you had the iWalk app running at the time, it will remember what direction you got to when you restart your phone and run the app again, so you can continue from where you were. We strongly recommend investing in an external battery and ensuring it's fully charged before you set out, so you don't get stuck half way around a walk with no app to guide you back.
Can I use the app to do the walk in the opposite direction?
This is not possible for two main reasons:
- For many walks there is an "optimal" direction with the best views, least steep gradients etc.
- The direction wording/landmarks and geolocation are all predicated on doing the walk in a particular direction. This information is triple-tested in the field which already requires a substantial amount of effort. An alternative set of directions for the reverse route would require the same level of testing which would nearly double the production and maintenance costs of the route navigation information. Currently there are not enough people using the app to justify these costs. If this changes in the future, it's something we'd like to be able to offer, particularly for walks where the merits of the forward vs reverse routes are more equal.
As well as the obvious lack of directions, this is not recommended:
- All other paths you're likely to notice are shown on the map within the app to help you find your bearings when you are on the route. Not all of these have public rights of way. Their presence on the map does not imply a right of way. You should consult an OS map or the Cornwall Council mapping service if you want to determine if there is a public or permissive right of way along a footpath not on the walk route.
- Paths which are not on the route have not been checked for positional accuracy to the level that the paths forming the route have.
How do I leave an app review?
From the Home page, press "More options" > "Review the app", or when you complete a walk using the app, press the "Review the app" button that appears on the walk summary page. This opens the App Store page for the app, where you can leave a review. Alternatively, follow the instructions below:
Open the App Store, press the "Purchased" button at the bottom of the screen and tap the iWalk Cornwall entry in the list. Tap the Reviews tab and then "Write a Review".
Open the Play Store app, press the menu icon (3 lines in the top-left corner of the screen), then select "My apps". Scroll down and tap on the iWalk Cornwall entry in the list. Scroll down to find "Rate this app" with 5 star icons below it. Tap the number of stars you want to rate the app with, fill out a title and description for the review, then tap Submit.
On Android is there a way to include walks previously purchased as single apps within "My walks"?
We'd very much like to be able offer this but due to the way Google handles apps and in-app purchases, walks you bought as individual apps before we moved to the single app model will not be restored under the "My walks" section of the new single app. This is because Google doesn't provide any mechanism for the "new" app to know if you'd previously bought a walk which used the old model (1 walk per app). Even if you told us which walks you'd previously bought, we couldn't make those available to you in the new app because the ownership data is held by Google via Google Play and there is currently no way for us to feed into that.
The single walk apps you have already purchased will remain permanently available to download again in the Play Store, so long as the Google account set up on your phone/tablet is the same one you used to buy them in the first place. There is no charge for this and you can re-download them as many times as you like and uninstall them when you are not using them. To re-download, open the Play Store app, go to My apps, click the ALL tab, and all apps previously purchased under your Google Account will be listed here - this allows you to re-install those you have previously bought but are not currently installed on the device. Although these will not appear under the "My walks" section of the "new" iWalk Cornwall app, they can be launched as individual apps via the Android start menu.
While this sign is displayed, the app cannot track your position to give you relevant direction information.
If the app is denied access to the device location, this sign will appear. The first time you enter navigation mode, you will be asked if you wish to allow the app access to your location. You must answer "OK" to enable the app to navigate. If you tapped "Don't Allow" by accident, go to the Settings app, select Privacy, then Location and turn on location services for this app.
This sign may also appear if your device does not have a GPS receiver or it is not accessible. Note that while the iPhone and iPad-Mini have built-in GPS receivers, WiFi-only iPads (those that do not have a 3G sim card) do not. If you wish to use this app with an iPad that doesn't have an internal GPS receiver, you will need to purchase an external GPS receiver.
This sign will be displayed if your GPS receiver is turned off or the app can't access it for some reason. While this message is displayed, don't attempt to start the walk as the app cannot track your location to know that you've started.
If you've forgotten to turn your GPS receiver on, simple exit/switch out of the app, turn it on and switch back again. The app will detect the change when you switch back to it and begin seeking a GPS location fix.
If your device doesn't have a built-in GPS receiver, you'll need an external GPS receiver. These can be purchased on Amazon, for example, and can connect to your device via Bluetooth or USB. If you have an external GPS device and are seeing this sign, make sure the external receiver is switched on, your device has Bluetooth is switched on and that the external GPS receiver has been correctly "paired" with your device.
While this sign is displayed, the app cannot track your position to give you relevant direction information.
It is displayed when the GPS receiver your device is using is activated but a GPS fix has yet to be acquired. In order to track your position, the receiver must locate a minimum of 3 GPS satellites. When the walk navigation is started, this can take anywhere from a couple of seconds to a few minutes. You may also see this sign appear if your GPS receiver loses its location fix. This can occur when objects are obscuring the sky such as when you are under trees or between or inside building. The sign will disappear once a fix has been reacquired. If for some reason this sign doesn't disappear, try restarting your device.
The compass calibration screen keeps being shown
This is a "feature" of Apple devices when an app uses the compass and is triggered by the iOS operating system, not the app. You can reduce the chances of this happening by keeping your iPhone away from metallic objects in your pockets as these disturb the compass. Follow the on-screen instructions in order to dismiss this. If it becomes unbearably irritating, then in the iWalk App settings you can switch off the compass (although, obviously, you'll lose the benefit of knowing which way you are facing on the map).
Walks disappear from "My walks"
If an Apple device is running out of storage space, the operating system will delete application local storage data in a last-ditch attempt to free up space. If this causes your purchased walks to disappear, you can resurrect them after clearing some space on your device by using the "Restore purchases" button on the home screen. If possible, avoid setting out for a walk with a nearly full device as iOS may decide to delete your downloaded walks at an inopportune moment, such as in a location where you don't have a 3G signal to re-download them.
When you press the Camera button inside the app and use the camera to take a photo, you are then presented with a preview of the photo. You need to press the "OK" (or "tick") button to save the photo. Pressing any other button (or the hardware back button) will not save your photo.
Like any computer operating system, Android has its share of bugs. In this section we’ve documented any bugs we've seen affect the app which are beyond our control. They are all rare, so it’s quite likely you will never encounter any of them, but if you do, we’ve listed the symptoms and what to do to get the app up and running again so you can carry on with your walk.
The minimum supported version of Android is 4.1 (Jelly Bean). We do not support Android 4.0 (Ice Cream Sandwich) or below because these versions contain significant bugs which seriously impair the functioning of the app. While you may attempt to use the app on unsupported versions, we highly recommend you use the app on Android 4.4 or above.
Android 4.2 and 4.3 contain some bugs which affect the graphical user interface of the app. Whilst we've done our best to work around these bugs, it's possible symptoms will still occur causing the app to display incorrectly. If you are running Android 4.2 or 4.3, we recommend upgrading to at least Android 4.4, where these issues with the graphics engine have been fixed.
Android 5.0 has some memory leaks, performance and app stability issues which impacts running apps including ours. We strongly recommend upgrading to 5.1 or later, as soon as an update is available for your device.
Android 6.0 introduces "run-time permissions". This means, the first time the app needs access to some functionality on the device, a box pops up to ask for your permission to use it. It is imperative that you "Allow" the app to use the requested permissions, otherwise it will not be able to function correctly. If you accidentally press "Deny", the best thing to do is to exit the app and start it again - this will cause it to re-request the permission, popping up the authorisation box again.
After pressing "Deny" the first time a permission is requested, the second time the popup box is displayed, there's also a checkbox that says "Never Ask Again". If you accidentally check this and then press "Deny", the app is never allowed to ask for that permission again. To remedy this, you must do the following: start the Settings app, go to Apps -> iWalk Cornwall -> Permissions, and ensure all the permission switches are on.
This is one of the symptoms of the graphics bugs in Android 4.2 and 4.3. This should only happen the first time the map is displayed and can be fixed by either scrolling or zooming the map, which will happen automatically during a walk if the "Autoscroll map" box is ticked on the Settings page.
This is another symptom of the 4.2 and 4.3 graphics bugs. If you do see this happen, pinch zoom the map and the problem should fix itself.
This is a bug in Android affecting Android versions up to and including 7. A workaround is as follows:
- Uninstall the app on the device(s).
- Go to the Play Store app on your device and select the account you want to use.
- Sign in to the Google Play website from a computer with the same correct account.
- Install the app through the Play website by clicking on "Install" button and choosing desirable device from the list.
- Wait a minute for silent install of the app on your device.
- Restore your purchases
You can double-check which walks have been purchased with which Google Account by reviewing your order history.
So long as the iWalk app is selected as the current app (in the "foreground") during a walk, the app will keep running and track your progress, even if the screen is switched off. However, if you switch to use another app during a walk while the iWalk app is running (putting it in the "background"), Android may decide to close the iWalk app to save system resources. If this happens, the iWalk app will no longer be able to track your route progress, so you won't get alerted when you reach a direction point or go off-route. If this happens, when you switch back to the iWalk app, it will restart (displaying the iWalk "boot" logo) and then will automatically resume your current walk and start route tracking again. If you have passed a number of direction points before noticing the app wasn't tracking your progress, the app may not be up-to-date with your current progression through the walk. To remedy this, on the directions screen you can tap on the direction marker before your position shown on the map and select navigate from the current direction, to tell the app where to resume the walk from.
