# FeynmanStudy vs Memzi

The clearest difference is iOS requirement: FeynmanStudy at 15.1 against Memzi's 17. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. FeynmanStudy sells 3 in-app purchases, starting at $10.00 per 7 days and Memzi sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
