AB Mobile and Ballistic AE both work well.
If you're using an MOA scope, make sure you confirm whether its True MOA or Shooter MOA (IPHY - Inch Per Hundred Yards). Many MOA scopes are really IPHY. It makes a BIG difference and is probably the #1 reason why some people's app never matches their real life trajectory.
Ex: if you want to put on 40 MOA for 1000 yards:
SMOA (IPHY): 40 x 1" x 10 = 400"
TMOA: 40 x 1.047" x 10 = 418.8"
18.8" is pretty far off. The 0.047" seems small... until you multiply it 400x
