# Peptide Tracker vs Pept Colony

The clearest difference is update cadence: Peptide Tracker at fortnightly against Pept Colony's every 7 months. Peptide Tracker also leads on ratings volume (442 vs 8) and rating (4.8 vs 4.5). Pept Colony's advantage is review sentiment (100% vs 77%) and iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Peptide Tracker sells 7 in-app purchases, starting at $0.99 per 7 days and Pept Colony sells 2 in-app purchases, starting at $19.99 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 442 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 77% of Peptide Tracker's written reviews are positive against 100% of Pept Colony's, so the app with the better star average is not the one people write more warmly about.

Peptide Tracker ships an update fortnightly, Pept Colony every 7 months. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
