# PepTracker vs PeptideLab

The clearest difference is update cadence: PeptideLab at daily against PepTracker's every 2 weeks. PeptideLab also leads on review sentiment (93% vs 77%) and iOS requirement (15.1 vs 18). PepTracker's advantage is ratings volume (413 vs 20). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. PepTracker sells 2 in-app purchases, starting at $4.99 per month and PeptideLab sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for PepTracker against 4.8 for PeptideLab. That said, the two scores are not equally well evidenced: PepTracker has 413 ratings behind it against 20, so its average is the more settled of the two. Written reviews are what separate them: 77% of PepTracker's written reviews are positive against 93% of PeptideLab's.

PepTracker ships an update every 2 weeks, PeptideLab daily. The most recent releases landed on September 11, 2026 and September 23, 2026 respectively.
