# Mechanical Formula vs VibSolutions

The clearest difference is iOS requirement: Mechanical Formula at 13.0 against VibSolutions's 15.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Mechanical Formula sells 1 one-off in-app purchase and VibSolutions sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
