# Prep vs Todaii

Prep and Todaii both sit at 4.6 stars, but that hides the real split: 86% of Prep's written reviews are positive against 67% of Todaii's. Prep also leads on update cadence (every 5 days vs fortnightly) and ratings volume (123 vs 28). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Prep sells 10 one-off in-app purchases and Todaii sells 10 in-app purchases, starting at $13.00 per 3 months. Whichever you choose, the download price is not the number that matters.

Todaii holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 123 and 28 respectively. Written reviews complicate that: 86% of Prep's written reviews are positive against 67% of Todaii's, so the app with the better star average is not the one people write more warmly about.

Prep ships an update every 5 days, Todaii fortnightly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
