# COMPOUND vs PeptideLab

The clearest difference is monetization model: PeptideLab at free with in-app purchases against COMPOUND's subscription. PeptideLab also leads on ads (none vs shown) and update cadence (every 2 days vs every 9 days). COMPOUND's advantage is rating (5.0 vs 4.7). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. COMPOUND sells 6 in-app purchases, starting at $6.99 per 7 days and PeptideLab sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

COMPOUND holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PeptideLab has 29 ratings behind it against 4, so its average is the more settled of the two.

COMPOUND ships an update every 9 days, PeptideLab every 2 days. Both last shipped on November 5, 2026.
