# 易课时 vs TimeFlow

The clearest difference is update cadence: TimeFlow at every 2 days against 易课时's every 2 months. 易课时's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 易课时 sells 5 in-app purchases, starting at $69.99 per year and TimeFlow sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

易课时 ships an update every 2 months, TimeFlow every 2 days. Both last shipped on October 25, 2026.
