# Pics21 vs Class Notes

The clearest difference is update cadence: Pics21 at every 2 days against Class Notes's every 5 days. Pics21 also leads on ratings volume (6 vs 1) and iOS requirement (12.0 vs 18.1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Pics21 sells 1 one-off in-app purchase and Class Notes sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
