# The Peptide App vs Dosebook

The clearest difference is update cadence: Dosebook at daily against The Peptide App's every 5 days. Dosebook also leads on rating (5.0 vs 4.7). The Peptide App's advantage is monetization model (free vs freemium) and ratings volume (114 vs 7). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. The Peptide App sells 4 in-app purchases, starting at $4.99 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 4.7. That said, the two scores are not equally well evidenced: The Peptide App has 114 ratings behind it against 7, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

The Peptide App ships an update every 5 days, Dosebook daily. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
