# Peptide Log vs Peptide Tracker

The clearest difference is rating: Peptide Tracker at 4.8 against Peptide Log's 4.2. Peptide Tracker also leads on monetization model (free with in-app purchases vs subscription). Peptide Log's advantage is ads (none vs shown) and review sentiment (75% vs 50%). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Peptide Log sells 2 in-app purchases, starting at $8.99 per month and Peptide Tracker sells 12 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Peptide Tracker holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 35 and 102 respectively. Written reviews complicate that: 75% of Peptide Log's written reviews are positive against 50% of Peptide Tracker's, so the app with the better star average is not the one people write more warmly about.

Peptide Log ships an update every 8 days, Peptide Tracker weekly. The most recent releases landed on October 2, 2026 and October 15, 2026 respectively.
