Calorie-Counter by Cronometer

Master your nutrition with precise calorie and micronutrient tracking

Calorie-Counter by Cronometer stands out as a serious tool for anyone who wants more than a basic food diary. Instead of just tallying calories and macros, it digs deep into your nutrition, tracking an impressive 84 micronutrients so you can see exactly which vitamins and minerals you’re getting enough of – and where you’re falling short.

The app’s database is one of its biggest strengths. With over a million verified foods drawn from lab-tested sources, entries feel far more reliable than the user-generated lists you see elsewhere. Logging is smooth and flexible: you can search, use the built-in barcode scanner, or save custom recipes and favorite meals to speed up repeat entries.

Cronometer also works well as a central hub for your overall health data. It syncs with popular wearables and services like Fitbit, Garmin, and Dexcom, pulling in activity, heart rate, and blood glucose data. Add in water tracking, sleep logging, and customizable charts, and you get a detailed, data-rich overview of how your habits interact.

For weight loss or muscle gain, the goal-based tools are genuinely helpful. You can set calorie and macro targets, then watch your daily diary and progress charts update in real time. The nutritional target wizard makes initial setup straightforward, even if you’re not an expert.

That said, this depth comes with a learning curve. The interface can feel busy at first, and casual users who just want a quick calorie total may find the level of detail overwhelming. Some of the more advanced analysis and customization is locked behind the paid Gold tier as well.

If you’re serious about evidence-based nutrition tracking and want lab-level detail in your pocket, Calorie-Counter by Cronometer is one of the most robust options available.
