Gravity Ballistics

I know I have to dial up 9 MOA at 500 yards. This app says 45. Assuming that’s 45 inches of drop. Ok great. Now if I shoot at 750yards, what’s the MOA? I have to do the math? Is there an app for that?

I need 50 yard zero for 22lr and 25 yard increments rather than 100 yard. Great concept but not usable for my use case until it gets that.

I have had this for a bit. Haven’t had any issues with the app and the trueing process is easy and accurate I am curious to see about the app adding some variations for different temperatures and angle values ( cosine / high angle shooting ) as per zero vs zero change due to factors mentioned Almost would like to a primary zero and a secondary zero for one profile pending the changes noted; angle of fire, temperature etc
