Questions about Heza, answered.

Heza is a fitness and nutrition tracker. It puts what you eat, how you lift, how you run and how you recover in one place, and lets your own AI assistant act as your coach.

Yes. Heza is in early access and free to use. Sign up at my.heza.app and start right away.

No. Everything works in the app on its own: food search and barcode scanning, live workout logging, runs, plans and progress. Connecting an AI is the fast way to log and ask questions, not a requirement.

Claude, ChatGPT and any other AI assistant that supports MCP connectors. Add Heza once with a link and sign in (in ChatGPT, turn on developer mode first).

No. Heza uses the AI plan you already have. There is no extra AI fee from Heza.

By voice or text, it can log meals (even from a photo), workouts and runs, plan your week and review your progress against your goal. It also writes coach notes in the app, and it only sees your own data.

Garmin and COROS. Heza syncs every hour: activities, calories burned, steps, sleep (optional), HRV, resting heart rate, VO2 max, training load and recovery. Planned runs are sent to your watch as structured workouts.

Yes. Type your daily numbers in by hand, or import runs from FIT, GPX or TCX files.

You, the AI assistant you connect (only your own data), and the small Heza team that runs the server. There are no ads, your data is never sold, and you can export it or delete your account in Settings at any time.

Heza is new and still changing. Features are added often and some things may move around. Your feedback shapes what comes next.

Food search uses the USDA FoodData Central database and Open Food Facts, plus a shared food database that Heza users build together. Foods whose numbers come from a barcode or a label, or that the Heza team verified, are marked Checked.

Yes. The in-app scanner reads barcodes with your phone camera. If you send your AI a photo of a package, it reads the barcode digits in the picture and looks the food up.

From your history and effort. If last time you did 3 sets of 10 at 25 kg with 2 reps in reserve, Heza suggests trying 27.5 kg. You can log effort as RPE or reps in reserve.

Yes. Lifting calories come from your watch when it recorded the session, or Heza estimates them. You choose whether they count toward what you burned.

Planned runs as structured workouts, plus weigh-ins and water you log in Heza. It is on by default and you can turn each one off in Settings. Garmin does not accept meal logs from other apps, so food stays in Heza.

Yes. Download everything from Settings as one JSON file or as spreadsheets (CSV).

In Settings, choose Delete my account. It happens right away and your data is removed from backups within 14 days.
