# Protocol vs Peptide Manager

The clearest difference is device support: Peptide Manager at 4 against Protocol's 2. Peptide Manager also leads on iOS requirement (15.5 vs 26.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Protocol sells 2 in-app purchases, starting at $2.99 per month and Peptide Manager sells 16 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
