# Peptide Tracker vs Pepti

The clearest difference is review sentiment: Pepti at 98% against Peptide Tracker's 50%. Pepti also leads on update cadence (every 2 days vs weekly). Peptide Tracker's advantage is ratings volume (114 vs 2) and rating (4.8 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Peptide Tracker sells 12 in-app purchases, starting at $7.99 per 7 days and Pepti sells 3 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

Peptide Tracker holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Peptide Tracker has 114 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Peptide Tracker's written reviews are positive against 98% of Pepti's, so the app with the better star average is not the one people write more warmly about.

Peptide Tracker ships an update weekly, Pepti every 2 days. The most recent releases landed on October 19, 2026 and October 21, 2026 respectively.
