# COMPOUND vs PeptideLab

The clearest difference is update cadence: PeptideLab at daily against COMPOUND's every 9 days. PeptideLab also leads on ratings volume (27 vs 4). COMPOUND's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. COMPOUND sells 5 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 4.8. That said, the two scores are not equally well evidenced: PeptideLab has 27 ratings behind it against 4, so its average is the more settled of the two.

COMPOUND ships an update every 9 days, PeptideLab daily. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
