# PepLog vs ThePeptideList

The clearest difference is review sentiment: ThePeptideList at 100% against PepLog's 50%. ThePeptideList also leads on in-app purchases (none vs 1) and update cadence (daily vs every 3 months). PepLog's advantage is rating (4.0 vs 3.7) and iOS requirement (15.1 vs 17.0). On price, ratings volume, ads and monetization model there is nothing between them.

Both are free to download. PepLog sells 1 one-off in-app purchase. ThePeptideList asks for nothing beyond the download.

PepLog holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 2 and 3 respectively. Written reviews complicate that: 50% of PepLog's written reviews are positive against 100% of ThePeptideList's, so the app with the better star average is not the one people write more warmly about.

PepLog ships an update every 3 months, ThePeptideList daily. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
