Ratings and Reviews
Works in the Alps!
I saw the poor reviews but thought as it is free I'd give it a go. I live in Switzerland and have just taken this app on a long trek ranging over altitudes at lake level (480m) to a mountain pass (2300m). I got pretty accurate readings all the time - I compared with a map of the region. It works fine for me so far!
Works fine for me :)
I travel all around the UK in my job and this app seems to give pretty accurate readings where ever I am. 5 deserving stars from me, would give more if I could
Accurate to within 40m
My apologies to the developer. I said my phone was reading 0m instead of 100 metres by the Ordnance Survey map. I hadn't realised it wasn't seeing any satellites. A slightly different position on the same level gives it at 140 and 142 m rather than 100 m. Once again, my apologies.
Up to six family members will be able to use this app with Family Sharing enabled.
