# Cogni vs Todait

The clearest difference is ratings volume: Cogni at 1.7K against Todait's 1. Cogni also leads on update cadence (every 9 days vs every 3 weeks) and iOS requirement (16.4 vs 26.0). Todait's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cogni sells 9 in-app purchases, starting at $4.99 per month and Todait sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Todait holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Cogni has 1.7K ratings behind it against 1, so its average is the more settled of the two.

Cogni ships an update every 9 days, Todait every 3 weeks. The most recent releases landed on October 30, 2026 and October 20, 2026 respectively.
