Verdict
The clearest difference is monetization model: PeptideFox at free against MyPep's free with in-app purchases. PeptideFox also leads on rating (5.0 vs 4.7) and iOS requirement (17.0 vs 26.0). MyPep's advantage is update cadence (every 2 days vs weekly) and ratings volume (20 vs 4). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PeptideFox sells 2 in-app purchases, starting at $2.99 per month and MyPep sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
PeptideFox holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: MyPep has 20 ratings behind it against 4, so its average is the more settled of the two.
PeptideFox ships an update weekly, MyPep every 2 days. Both last shipped on October 25, 2026.
