# Zhi vs OnlyU+

The clearest difference is device support: Zhi at 4 against OnlyU+'s 1. Zhi also leads on iOS requirement (15.6 vs 17.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Zhi sells 2 in-app purchases, starting at $4.99 per month and OnlyU+ sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
