# Zempy vs Calorie Tracker

The clearest difference is rating: Calorie Tracker at 4.7 against Zempy's 4.2. Calorie Tracker also leads on review sentiment (88% vs 63%) and ratings volume (1.5K vs 38). Zempy's advantage is update cadence (every 3 days vs every 6 days) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zempy sells 6 in-app purchases, starting at $9.99 per month and Calorie Tracker sells 10 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Calorie Tracker holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Calorie Tracker has 1.5K ratings behind it against 38, so its average is the more settled of the two. Written reviews point the same way: 63% of Zempy's written reviews are positive against 88% of Calorie Tracker's.

Zempy ships an update every 3 days, Calorie Tracker every 6 days. Both last shipped on October 30, 2026.
