# Caffeine App vs CaffeineLog

The clearest difference is update cadence: CaffeineLog at every 2 days against Caffeine App's monthly. CaffeineLog also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 74%). Caffeine App's advantage is ratings volume (341 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Caffeine App sells 1 one-off in-app purchase and CaffeineLog sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

CaffeineLog holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Caffeine App has 341 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 74% of Caffeine App's written reviews are positive against 100% of CaffeineLog's.

Caffeine App ships an update monthly, CaffeineLog every 2 days. Both last shipped on October 24, 2026.
