Must have for hiking in the UK

If you’re going hiking in the UK and not taking this app on your smartphone then you are a fool.

Definitely worth the cost of the premium version to get access to the detailed maps and offline maps.

OS maps always had amazing accuracy and detail - now you can use gps on your phone to see exactly where you are among all that detail.

Great for planning free form hikes to get you off the beaten path.

Only thing the app can’t tell you is the condition of the trail or footpath you are going to hike on - huge clumps of stinging nettles are a real thing - but you can use the app to replay your hike on the fly to avoid whatever you encounter that you don’t want to deal with.

All this for less than the cost of a single paper map - it’s a bargain!

Doesn’t work when connected to the internet

Update. The app works great with no internet connection. Disable mobile data for the app and it works great.

Having purchased paper maps, I’ve used this app to download the off-line version. The app continually requires me to re-login, and I frequently have to re-download, or at least verify the download, before I can use the maps. Horribly flaky behaviour.

Developer Response ,

Thank you for your feedback, we're sorry to hear you've experienced issues with the app logging you out. We are aware of an issue affecting some users which causes them to be logged out while using both Android and iOS versions of OS Maps and we’re currently investigating. It appears to be affecting users who have lost their signal and cannot connect to the internet within a two-hour period. Until this is resolved please login as soon as you receive a network connection. We hope to resolve this soon with a future update.
