# 作业批改 vs Tutor

The clearest difference is device support: 作业批改 at 3 against Tutor's 1. 作业批改 also leads on iOS requirement (9.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 作业批改 sells 4 in-app purchases, starting at $1.99 per 7 days and Tutor sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
