This app doesn't work. The GPS does not work. Disabling battery optimization will not solve the gps issue. I want my money back. If you want an app that works, download trailforks. I will be blasting them with emails until I get my money returned. I feel like I've been ripped off. This app has only gotten me lost and caused me total frustration. After googling and trying fixes for 2 weeks, I downloaded trailforks and it worked great with no issues. Do not pay for this app. It does not work.
