# Peptide Protocol vs Protocol

The clearest difference is monetization model: Protocol at free against Peptide Protocol's subscription. Protocol also leads on ads (none vs shown) and update cadence (every 2 days vs every 5 days). Peptide Protocol's advantage is ratings volume (14 vs 1). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Peptide Protocol sells 9 in-app purchases, starting at $4.99 per 7 days and Protocol sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Peptide Protocol against 5.0 for Protocol. That said, the two scores are not equally well evidenced: Peptide Protocol has 14 ratings behind it against 1, so its average is the more settled of the two.

Peptide Protocol ships an update every 5 days, Protocol every 2 days. Both last shipped on November 5, 2026.
