This app has earned zero- no, a negative 5 stars. Every recording zeros when I press "finish and save". I have repeatedly messaged alltrails with zero issues being resolved. They need a new coding team. Alltrails told me it was my phone's error, not their problem. Strava works pertectly on my android. Gai works perfectly on my phone. Alltrails IS the problem. I understand why 99% of runners choose Strava!
