# 一课 vs StudyRank

The clearest difference is in-app purchases: StudyRank at none against 一课's 3. 一课's advantage is review sentiment (88% vs 62%) and update cadence (every 3 weeks vs every 6 weeks). On price, ads and device support there is nothing between them.

Both are free to download. 一课 sells 3 one-off in-app purchases. StudyRank asks for nothing beyond the download.

一课 ships an update every 3 weeks, StudyRank every 6 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
