Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
On the App Store both sit at effectively the same score — 5.0 for Pics21 against 5.0 for Class Notes. That said, the two scores are not equally well evidenced: Pics21 has 6 ratings behind it against 1, so its average is the more settled of the two.
Pics21 ships an update every 2 days, Class Notes every 5 days. The most recent releases landed on October 7, 2026 and September 6, 2026 respectively.
