# Study AI vs Tail Trainer

The clearest difference is update cadence: Tail Trainer at every 2 days against Study AI's every 2 weeks. Study AI's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Study AI sells 4 in-app purchases, starting at $6.99 per 7 days and Tail Trainer sells 3 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Study AI ships an update every 2 weeks, Tail Trainer every 2 days. The most recent releases landed on October 27, 2026 and October 25, 2026 respectively.
