# Peptide Log vs PepTracker

The clearest difference is monetization model: PepTracker at freemium against Peptide Log's subscription. PepTracker also leads on rating (4.7 vs 4.2) and ratings volume (413 vs 35). Peptide Log's advantage is update cadence (every 8 days vs every 2 weeks). On price, review sentiment, ads 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 PepTracker sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

PepTracker holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: PepTracker has 413 ratings behind it against 35, so its average is the more settled of the two. Written reviews point the same way: 75% of Peptide Log's written reviews are positive against 77% of PepTracker's.

Peptide Log ships an update every 8 days, PepTracker every 2 weeks. The most recent releases landed on August 1, 2026 and September 11, 2026 respectively.
