# 小象脑力 vs 印章

The clearest difference is update cadence: 印章 at every 10 days against 小象脑力's every 2 months. 小象脑力's advantage is iOS requirement (9.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 小象脑力 sells 18 in-app purchases, starting at $10.49 per 7 days and 印章 sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

小象脑力 ships an update every 2 months, 印章 every 10 days. The most recent releases landed on September 29, 2026 and October 7, 2026 respectively.
