# Peptide AI vs PepLog

The clearest difference is monetization model: PepLog at free against Peptide AI's freemium. PepLog also leads on review sentiment (100% vs 76%). Peptide AI's advantage is update cadence (weekly vs fortnightly) and ratings volume (75 vs 25). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Peptide AI sells 4 in-app purchases, starting at $6.99 per 7 days and PepLog sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Peptide AI against 4.4 for PepLog. Both are backed by a comparable volume of ratings — 75 and 25 respectively. Written reviews are what separate them: 76% of Peptide AI's written reviews are positive against 100% of PepLog's.
