Opinions on Geoballistics app?

I have a few different ballistics calculator apps that I have been playing with but the one that I am finding by far the easiest and most intuitive to use is the Geoballistics app, plus that is the only one I can get to pair with my Weatherflow meter. I’d love a Kestrel, but just can’t justify spending an extra $700 just for app pairing.

Anyway, what are your opinions on the app? How does it compare accuracy wise to Applied Ballistics quantum app and Hornady 4dof? Am I at any real disadvantage using the Geoballistics app?

AB Quantum, or an AB Kestrel, or anything AB really, allows use of AB CDMs (custom drag models) of many popular bullets , along with Personal Drag Models of the same bullets. That is the sauce that makes the dish. All the apps are using relatively basic math that is not difficult for geeks to calculate and write. Some are more user friendly, or have better features. The biggest hurdle is users who get lazy and religiously committed to some very basic app because they believe some self appointed guru, usually parroting buzz words from 2 decades ago, who is quietly sponsored by one of the big industry players. My young son calls it “fudd lore”.
