# Geek Math vs 记密码

The clearest difference is ads: 记密码 at none against Geek Math's shown. 记密码 also leads on update cadence (every 3 weeks vs every 10 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Geek Math sells 1 one-off in-app purchase and 记密码 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Geek Math ships an update every 10 months, 记密码 every 3 weeks. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
