Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
