# PepTracker vs Pept Colony

The clearest difference is update cadence: PepTracker at every 3 weeks against Pept Colony's every 7 months. PepTracker also leads on ratings volume (468 vs 8) and rating (4.7 vs 4.5). Pept Colony's advantage is review sentiment (100% vs 78%) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PepTracker sells 8 in-app purchases, starting at $7.99 per month 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.

PepTracker holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: PepTracker has 468 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 78% of PepTracker'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.

PepTracker ships an update every 3 weeks, Pept Colony every 7 months. The most recent releases landed on October 25, 2026 and October 8, 2026 respectively.
