# AI教师助手 vs 极简

The clearest difference is device support: AI教师助手 at 3 against 极简's 1. AI教师助手 also leads on iOS requirement (12.0 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AI教师助手 sells 1 one-off in-app purchase and 极简 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

AI教师助手 ships an update every 3 weeks, 极简 fortnightly. The most recent releases landed on October 27, 2026 and October 29, 2026 respectively.
