The basics

What is Heza?

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

How is Heza different from other fitness apps?

Heza puts food, lifting, runs and recovery in one free app, with no ads and no Premium tier. It works with the watch you choose: Garmin and COROS sync every hour and receive your planned runs, and other watches import files. And it works with the AI you already use: Claude, ChatGPT or any assistant with MCP connectors can log meals and workouts, plan your week and write coach notes, not only read your data. Heza adds no AI fee and no daily AI limit.

Is Heza free?

Yes. Heza is free: no subscription, no ads, and no extra fee for the AI. Sign up at my.heza.app and start right away.

Do I need an AI assistant to use Heza?

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.

Which AI assistants work with Heza?

Claude, ChatGPT and any other AI assistant that supports MCP connectors. Add Heza once with a link and sign in. In ChatGPT, this depends on your plan.

Do I need to pay for another AI subscription?

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

What can my AI do in 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.

Which watches does Heza support?

Heza is built to work with the watch you choose. Garmin and COROS connect directly and sync every hour: activities, calories burned, steps, sleep (optional), HRV, resting heart rate, VO2 max, training load and recovery, and planned runs are sent to the watch as structured workouts. With another watch, import your runs and workouts as FIT, GPX or TCX files. More brands are on the way, and Heza works without a watch too.

I don't have a watch. Can I still use Heza?

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

Is there an iPhone or Android app?

Heza is an installable web app. Add it to your home screen on iPhone or Android, or install it on your desktop. It opens full screen like any other app and can send reminders. How to install it.

How do I install Heza?

Open my.heza.app on your phone. On iPhone, tap Share in Safari, then Add to Home Screen. On Android, tap Install app when Chrome offers it, or open the menu and tap Add to Home screen. It takes under a minute. See the steps with pictures.

Who can see my data?

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

Food, training and your data

Where does the food data come from?

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.

Can I log food with a barcode?

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.

How does Heza suggest my next weight?

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.

Does Heza count the calories I burn lifting?

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.

What gets sent to my Garmin?

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.

Can I export my data?

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

How do I delete my account?

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

Is Heza medical advice?

No. Calories, targets, training loads and coach notes are estimates to help you. Check with a professional before big changes to your diet or training.
