# Peptide Vault vs Protocol

The clearest difference is monetization model: Protocol at free against Peptide Vault's subscription. Protocol also leads on update cadence (every 2 days vs weekly). Peptide Vault's advantage is ratings volume (9 vs 1) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Peptide Vault sells 11 in-app purchases, starting at $9.99 per month 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 Vault against 5.0 for Protocol. That said, the two scores are not equally well evidenced: Peptide Vault has 9 ratings behind it against 1, so its average is the more settled of the two.

Peptide Vault ships an update weekly, Protocol every 2 days. The most recent releases landed on October 12, 2026 and October 2, 2026 respectively.
