# First Flight Calculator vs Acceleration Calculator

The clearest difference is ads: Acceleration Calculator at none against First Flight Calculator's shown. Acceleration Calculator also leads on monetization model (free vs ad-supported) and iOS requirement (11.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
