# Cere vs Study Ducky

The clearest difference is update cadence: Cere at every 10 days against Study Ducky's every 4 weeks. Cere also leads on iOS requirement (12.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cere sells 5 in-app purchases, starting at $4.99 per month and Study Ducky sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

Cere ships an update every 10 days, Study Ducky every 4 weeks. The most recent releases landed on October 16, 2026 and October 12, 2026 respectively.
