# Calorie Tracker vs NutriOn

The clearest difference is rating: NutriOn at 5.0 against Calorie Tracker's 4.7. NutriOn also leads on update cadence (every 3 days vs weekly) and device support (3 vs 1). Calorie Tracker's advantage is ratings volume (15 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calorie Tracker sells 2 in-app purchases, starting at $2.99 per 7 days and NutriOn sells 5 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

NutriOn holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Calorie Tracker has 15 ratings behind it against 1, so its average is the more settled of the two.

Calorie Tracker ships an update weekly, NutriOn every 3 days. The most recent releases landed on November 5, 2026 and October 30, 2026 respectively.
