Barcode scanner

Scan it, check it, log it.

Point your camera at a barcode and the food comes up with its label values. Foods whose numbers come from a barcode or label, or that the Heza team verified, carry a Checked badge.

  • Big food search USDA FoodData Central and Open Food Facts.
  • Community foods A shared database Heza users build together.
  • Your foods Add your own foods, private or shared.
  • Saved meals Log your usual breakfast in one tap.
Scanning a barcode finds Greek yogurt, plain, 0% fat. 150 g is 86 kcal with 15 g protein, 5 g carbs and 0 g fat. It is marked Checked.

Eaten vs burned

See the whole week, not just today.

Heza compares what you ate with what you burned, every day. Pick a fixed calorie target or a dynamic one that grows with your active calories, and track protein, carbs, fat, fiber and water against your goals.

Log by voice

Or just tell your AI what you ate.

Tell Claude, ChatGPT or another AI assistant what you ate. It logs the right foods and portions, and reads the barcode in a photo.

How the AI coach works
You say "Two eggs and toast for breakfast" to your AI assistant. It logs 2 eggs and a slice of toast, 253 kcal and 17 g protein, and the meal appears in Heza's Fuel screen.

FAQ

Calorie tracker questions.

Is the calorie tracker free?

Yes. Heza is free during early access, including food search, the barcode scanner and saved meals.

How does eaten vs burned work?

Heza puts the calories you logged next to the calories your watch says you burned today, resting plus active. It updates as your watch syncs, so you always see where you stand.

What is a dynamic calorie target?

In dynamic mode your daily target is your base target plus the active calories you burn. Train more and you can eat more.

Can I track macros and water?

Yes. Protein, carbs, fat and fiber against your targets, plus water with a quick tap.
