# 极简速记 vs AI分身术

The clearest difference is update cadence: AI分身术 at every 2 months against 极简速记's every 15 months. 极简速记's advantage is iOS requirement (11.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

极简速记 ships an update every 15 months, AI分身术 every 2 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
