# 1Shelf vs Oopi

The clearest difference is iOS requirement: Oopi at 15.1 against 1Shelf's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 1Shelf sells 4 in-app purchases, starting at $9.99 per month and Oopi sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
