# Caffeine Clock vs CaffeineLog

The clearest difference is monetization model: Caffeine Clock at free against CaffeineLog's freemium. Caffeine Clock also leads on ratings volume (24 vs 3). CaffeineLog's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 80%). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Caffeine Clock sells 2 one-off in-app purchases 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 4.7. That said, the two scores are not equally well evidenced: Caffeine Clock has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 80% of Caffeine Clock's written reviews are positive against 100% of CaffeineLog's.

Caffeine Clock ships an update weekly, CaffeineLog every 2 days. The most recent releases landed on September 16, 2026 and July 21, 2026 respectively.
