# Peptide Log vs Dosebook

The clearest difference is rating: Dosebook at 5.0 against Peptide Log's 4.2. Dosebook also leads on monetization model (freemium vs subscription) and update cadence (daily vs every 8 days). Peptide Log's advantage is ratings volume (35 vs 6). On price, ads, in-app purchases and device support there is nothing between them.

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

Dosebook holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Peptide Log has 35 ratings behind it against 6, 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 100% of Dosebook's.

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