Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
