UK Map App


Frequently Asked Questions

Is there an Android version of this app?

No, not currently. Maybe eventually.

Some footpaths seem to be missing.

Because Ordnance Survey have not released any of their footpath data as part of the OpenData scheme, this app instead uses footpath data from This data has been collected by volunteers and the quality and coverage is generally excellent, especially in popular walking areas - but it is not yet entirely complete.

The GPS works in urban areas but not in the countryside.

If you have an iPod touch or a WiFi-only iPad, your device does not have a GPS. It is able to find your approximate location using nearby WiFi base stations, but this will only work in built-up areas.

I only see names for a few major roads.

You're probably only seeing the 1:25,000 maps, not the 1:10,000 maps.

First, check if you downloaded the 1:10,000 maps. If you view the "Map Management" screen, areas with 1:25,000 will be highlighted in green and those with 1:10,000 in yellow or beige, or stripes including those colours.

If that is OK, check the "Scales" section of the settings screen. Check that the slider between 1:25,000 and 1:10,000 is not at the extreme right; if necessary, move it to the left.

The app is not working properly, should I delete it and re-install it?


If you delete and re-install the app, you will lose all of your waypoints, recorded tracks, and downloaded maps. So that should be an absolute last resort.

The first thing to try is the "Start In Safe Mode" switch. This is in the main settings app, under "UK Map". Turn this on and try to restart the app. If necessary do this a couple of times. This will cause the app to re-index your downloaded maps and reset your settings. This may be enough to resolve your problem.

Note that "safe mode" will hide all of your GPX files. They are not deleted, just hidden. Unhide them from the Files screen.

If you have a problem of this sort, and especially if it is reproducible, do please get in touch so that it can be investigated.

What do the different path styles indicate?

Legends describing most map features can be found in the help screen, but these do not include paths and tracks because those have been overlaid separately. The styles used are similar to those used on Explorer maps:

Note, however, that these categories are only approximations. The OpenStreetMap categorisation of paths and tracks does not correspond exactly to the Ordnance Survey conventions, and may not be perfectly accurate in the first place. Walkers will generally find that these paths are all open to them; cyclists and horse riders should be more cautious.

How can I print maps?

Currently the best you can do is to take a screenshot (press the home and power buttons at the same time) and print that from the Photos app.

I have an iPhone and an iPad; do I need to purchase the app twice? Do I have to pay again if I delete and re-install the app? What about "Family Sharing"?

You can install and re-install the app on all your devices as many times as you like without paying again, as long as those devices are all associated with the same owner's "Apple ID".

The situation with "family sharing" is more complicated; I have tried not to enable this but Apple seem to have enabled it anyway, at least for some users. You may need to talk to Apple if you have difficulties related to this.

Why haven't you answered my email?

It's possible that my reply was categorised as junk by your email system. Check your junk email folder. I don't know exactly why this is, but presumably I am on someone's block list.
