# 洋葱学园 vs 思达伴学

The clearest difference is ads: 思达伴学 at none against 洋葱学园's shown. 洋葱学园's advantage is update cadence (fortnightly vs every 18 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 洋葱学园 sells 9 one-off in-app purchases and 思达伴学 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

洋葱学园 ships an update fortnightly, 思达伴学 every 18 months. The most recent releases landed on November 11, 2026 and November 8, 2026 respectively.
