Requirements for mountain nav app have not changed in last 10 yrs: offline map, stable, see route on map, see alternate user routes or points at same time if desired, heavy battery use only when referred to, easily create a waypoint at current location, personal preference on orient north or rotate/landscape/portrait. I would not use the app for tracking due battery drain but many want this. This fails on 3: not stable, no waypoints, no way to show alt routes or points. Get it working
