# Protocol vs Peptide Tracker

The clearest difference is monetization model: Protocol at free against Peptide Tracker's free with in-app purchases. Protocol also leads on rating (5.0 vs 4.7) and update cadence (every 2 days vs every 5 days). Peptide Tracker's advantage is ratings volume (52 vs 1) and iOS requirement (15.1 vs 17.5). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Protocol sells 2 in-app purchases, starting at $1.99 per 7 days and Peptide Tracker sells 10 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Protocol holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Peptide Tracker has 52 ratings behind it against 1, so its average is the more settled of the two.

Protocol ships an update every 2 days, Peptide Tracker every 5 days. The most recent releases landed on October 2, 2026 and October 14, 2026 respectively.
