# PepKit vs PepLog

The clearest difference is in-app purchases: PepLog at none against PepKit's 2. PepLog also leads on update cadence (every 2 weeks vs every 5 weeks) and review sentiment (100% vs 88%). PepKit's advantage is rating (4.9 vs 4.4) and ratings volume (158 vs 25). On price, ads and device support there is nothing between them.

Both are free to download. PepKit sells 2 in-app purchases, starting at $5.99 per 7 days. PepLog asks for nothing beyond the download.

PepKit holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: PepKit has 158 ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 88% of PepKit's written reviews are positive against 100% of PepLog's, so the app with the better star average is not the one people write more warmly about.

PepKit ships an update every 5 weeks, PepLog every 2 weeks. The most recent releases landed on October 22, 2026 and October 8, 2026 respectively.
