# Caffeine Tracker vs Shift

The clearest difference is in-app purchases: Shift at none against Caffeine Tracker's 4. Shift also leads on review sentiment (100% vs 79%). Caffeine Tracker's advantage is rating (4.9 vs 4.5) and ratings volume (40 vs 4). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Caffeine Tracker sells 4 in-app purchases, starting at $1.99 per month. Shift asks for nothing beyond the download.

Caffeine Tracker holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Caffeine Tracker has 40 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 79% of Caffeine Tracker's written reviews are positive against 100% of Shift's, so the app with the better star average is not the one people write more warmly about.

Caffeine Tracker ships an update every 6 days, Shift every 3 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
