# 九斗 vs RainClassroom

The clearest difference is rating: 九斗 at 4.0 against RainClassroom's 1.2. 九斗 also leads on update cadence (every 3 days vs every 2 months). RainClassroom's advantage is in-app purchases (none vs 10) and review sentiment (38% vs 10%). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. 九斗 sells 10 one-off in-app purchases. RainClassroom asks for nothing beyond the download.

九斗 holds the better App Store score, 4.0 against 1.2. Both are backed by a comparable volume of ratings — 8 and 17 respectively. Written reviews complicate that: 10% of 九斗's written reviews are positive against 38% of RainClassroom's, so the app with the better star average is not the one people write more warmly about.

九斗 ships an update every 3 days, RainClassroom every 2 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
