Someone showed me OSMAnd recently while we were hiking. I installed it as soon as I got home. Great for hiking.
Then last week I used it for navigation (on a phone with no SIM card).
Absolutely. Terrible.
Worst navigation app I've seen. Told me to make a turn at an intersection that did not allow turns. Then at another intersection, it told me to "Turn left", but the display clearly showed it going straight. I'm guessing that the straight road probably is angled 1 degree or something at the intersection and the app was viewing that as a turn.
I get similar navigation issues with Google maps. I still use Google maps for driving because the live traffic is important to me, but other posts on here mention other apps with live traffic so I'll give them a try.
For an open source Android app for OpenStreetMap data, I like Organic Maps, and it normally works great with locally-cached maps. I've had better luck with it than with Google Maps or Apple Maps on phones.
(Though, I should mention that twice in the last year I've had Organic Maps become hopelessly confused about where I was, and where I should go. Both times, it had gotten a good GPS location, but then got confused while being out for an extended period of time, like maybe it was dead-reckoning only after that initial lock.)
+1 for organic maps. Have used it hiking and travelling all over the world. Never had any issues with it.
Not had any GPS problems other than that time I was in an area where it was being jammed. Bloody Russians.
