# PeptideFox vs PeptideLab

The clearest difference is monetization model: PeptideFox at free against PeptideLab's freemium. PeptideLab's advantage is update cadence (daily vs weekly) and ratings volume (26 vs 3). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. PeptideFox sells 2 in-app purchases, starting at $2.99 per month 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.

PeptideFox holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PeptideLab has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of PeptideFox's written reviews are positive against 95% of PeptideLab's.

PeptideFox ships an update weekly, PeptideLab daily. The most recent releases landed on October 12, 2026 and October 20, 2026 respectively.
