# PROOF + vs Proof

The clearest difference is device support: PROOF + at 3 against Proof's 1. PROOF + also leads on iOS requirement (15.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.

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