# Calibrate vs Commit

The clearest difference is in-app purchases: Commit at none against Calibrate's 1. Commit also leads on iOS requirement (15.1 vs 17.6). On price, ads and device support there is nothing between them.

Both are free to download. Calibrate sells 1 one-off in-app purchase. Commit asks for nothing beyond the download.
