I have used it to test waypoints on my mini. I believe it is Android only.
Quoted from Red Waypoint website: Red Waypoint APP "Mission Modes Waypoint, Orbit, GPS Tracking, Virtual Stick, Tripod, Cinematic, Follow Terrain, Manual"
"* Note: Mavic Mini is not compatible with all features of RedWaypoint. It does not support Orbit Missions, Follow Me Missions and Active Track Missions."
