# Peptide Tracker vs Pep AI

Peptide Tracker and Pep AI both sit at 4.7 stars, but that hides the real split: 77% of Peptide Tracker's written reviews are positive against 35% of Pep AI's. Peptide Tracker also leads on ads (none vs shown). Pep AI's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (4K vs 310). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Peptide Tracker sells 7 in-app purchases, starting at $3.99 per 7 days and Pep AI sells 8 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Peptide Tracker against 4.7 for Pep AI. That said, the two scores are not equally well evidenced: Pep AI has 4K ratings behind it against 310, so its average is the more settled of the two. Written reviews are what separate them: 77% of Peptide Tracker's written reviews are positive against 35% of Pep AI's.

Peptide Tracker ships an update weekly, Pep AI every 6 days. The most recent releases landed on November 8, 2026 and November 9, 2026 respectively.
