# Peptide Protocol vs Strand

The clearest difference is monetization model: Strand at freemium against Peptide Protocol's subscription. Strand also leads on ads (none vs shown) and iOS requirement (15.1 vs 18.0). Peptide Protocol's advantage is ratings volume (14 vs 1) and update cadence (every 5 days vs every 11 days). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Peptide Protocol sells 11 in-app purchases, starting at $4.99 per 7 days and Strand sells 6 in-app purchases, starting at $6.99 per month. 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 Strand. 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, Strand every 11 days. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
