# Peptide Ninja vs PepsLab

The clearest difference is monetization model: Peptide Ninja at free with in-app purchases against PepsLab's subscription. PepsLab's advantage is update cadence (every 4 days vs fortnightly) and iOS requirement (15.1 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Peptide Ninja sells 1 in-app purchase, starting at $5.99 per month and PepsLab sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Peptide Ninja ships an update fortnightly, PepsLab every 4 days. Both last shipped on October 31, 2026.
