Do you want to know how much vitamin C you’ve gotten today? Or your omega 6 to 3 ratio? Or do you want to track a slight increase in protein consumption while reducing carbs? For anyone seeking a nutritional solution to any health issue or change, Cronometer is an essential tool. On top of that it works seamlessly across your devices with a clean interface that’s actually pleasant to use.

Cycling into and out of a state of nutritional ketosis can bring impactful benefits to almost everyone (consult your physician if you have any significant health challenges). And quantifying your daily ‘energy balance’ (food intake, exercise output) can be critical to your success. Over your day, Cronometer gives you live, on-the-go snapshots of not just calories in and carbs, protein and fat intake but vitamin and mineral levels and much, much more.

The free version is much more user-friendly than many free apps and may well be all you need. The monthly and annual costs are very reasonable if you find yourself wanting a deep dive into your nutritional performance.
