# 导学号 vs 红逗号

The clearest difference is in-app purchases: 导学号 at none against 红逗号's 10. 红逗号's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. 红逗号 sells 8 one-off in-app purchases. 导学号 asks for nothing beyond the download.

导学号 ships an update every 2 months, 红逗号 every 3 weeks. The most recent releases landed on October 4, 2026 and October 16, 2026 respectively.
