# 时间流 vs 课伴

The clearest difference is update cadence: 时间流 at every 3 days against 课伴's fortnightly. 时间流 also leads on device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. 时间流 sells 3 in-app purchases, starting at $0.99 per month and 课伴 sells 1 in-app purchase, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

时间流 ships an update every 3 days, 课伴 fortnightly. The most recent releases landed on October 17, 2026 and October 24, 2026 respectively.
