# 快乐学 vs 派效学

The clearest difference is update cadence: 派效学 at monthly against 快乐学's every 4 months. 快乐学's advantage is iOS requirement (9.0 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 快乐学 sells 10 one-off in-app purchases and 派效学 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

快乐学 ships an update every 4 months, 派效学 monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
