# 氢课 vs COE教练

The clearest difference is update cadence: 氢课 at every 3 weeks against COE教练's every 2 months. COE教练'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. Neither carries in-app purchases, so what you see is what you pay.

氢课 ships an update every 3 weeks, COE教练 every 2 months. Both last shipped on October 26, 2026.
