OS maps are the British standard and are a must for any outdoor person using navigation. I have used paper maps for years and it's easy to use the app alongside these with the benefit of GPS (always take a paper map as well though). Dropped a star because the route creating does some very strange things when you let it follow tracks, which should be the intuitive way to use it. Very frustrating. But app is good overall

I pay for premium membership to use the extra features of this app, like downloading routes to my device, but it is almost useless as it constantly shuts in the background and you only realise when you go back to it to check the next waypoint. Features like downloading a route and recording your trip are useless if you need to keep restarting every 10 minutes. On a hike right now and in what I think is 2 miles (hard to tell as the tracking has stopped twice) it's restarted 5 times already.

A GREAT APP WHEN IT WORKS. But it can go wrong at any moment - the phone battery can die; and the magic pink triangle can appear on the map literally miles from where you in fact are. This seems to happen most in misty weather when you need it most. Fixes are delete & reinstall, & recalibrate the phone compass (google it). The map on the phone is still there but it's much harder to use than a paper map, & the inbuilt compass is often wrong. Don't go anywhere wild without a paper map & compass.
