# COMPOUND vs Peptide Tracker

The clearest difference is monetization model: Peptide Tracker at free with in-app purchases against COMPOUND's subscription. Peptide Tracker also leads on ratings volume (86 vs 4). COMPOUND's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. COMPOUND sells 6 in-app purchases, starting at $6.99 per 7 days and Peptide Tracker sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

COMPOUND holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Peptide Tracker has 86 ratings behind it against 4, so its average is the more settled of the two.

COMPOUND ships an update every 9 days, Peptide Tracker every 6 days. Both last shipped on November 5, 2026.
