# ME2Go vs Engineering Formulas

The clearest difference is iOS requirement: ME2Go at 10.0 against Engineering Formulas's 15.1. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ME2Go sells 10 one-off in-app purchases and Engineering Formulas sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
