# Pocket Universe vs Mass.Shift

The clearest difference is iOS requirement: Mass.Shift at 13.0 against Pocket Universe's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Pocket Universe sells 3 in-app purchases, starting at $0.99 per month and Mass.Shift sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
