# Peptide Log vs Peptide Tracker

The clearest difference is monetization model: Peptide Tracker at free against Peptide Log's subscription. Peptide Log's advantage is rating (4.2 vs 3.7) and review sentiment (75% vs 60%). On price, update cadence, 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 Peptide Tracker sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Peptide Log holds the better App Store score, 4.2 against 3.7. That said, the two scores are not equally well evidenced: Peptide Log has 35 ratings behind it against 3, 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 60% of Peptide Tracker's.

Peptide Log ships an update every 8 days, Peptide Tracker every 4 days. The most recent releases landed on August 1, 2026 and September 24, 2026 respectively.
