Range calculating with Siii MOA-2 in mil-radians?

[Troymn]

I could not find any phone APP's to range calculate with MOA. I have mil-dot scopes and a "Mil-Dot" app. I was hoping to use my Sightron S111 8-32 with a mil-dot range estimation apt.
At 24x the scope has 2MOA=2.094" intervals, at 28.5x =1.6875 MOA =.5mil intervals. So if I set my scope at 28.5 it should be set to use as a mildot with 1/2 mil measurements.
Do you see anything wrong with my math or theory?

Using "Mil-dot ballistics" on my iphone, I was able to find a reticle in MOA rather than milradians. Hope it helps.
