Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
