There are other threads about it, but I quickly tried to connect with my bird, but it didn't connect for some reason. Even if it did work just as good or better than Litchi, I probably wouldn't use it because I only plan missions on Mission Hub due to ease. A mouse and a larger screen help a lot while planning my 7 mile + missions.
I hope this app or another from DJI is more user friendly so it can compete with Autopilot and Litchi.
