CoPilot Basic

I am interested in this app but its 40 bucks and has only two reviews, both one star? Any other viewpoints on here. Prolly just stick to AutoPilot which is AWESOME.
 
Don't like the word "basic" going to bring out a pro for more money? Plus it does not work with firmware from the dji site, you need developers version, where do you get that?. Dji will bring some more updates and will be like this, will save my money.
