How it works

Most trackers only count what goes in. Balanz counts both sides of the equation.

Connect Apple Health

Balanz reads resting energy, steps, workouts, weight and any food your other apps already write to Health.

Get an honest daily target

Your target is built from Mifflin-St Jeor, Harris-Benedict or Katch-McArdle, with a safe deficit already included โ€” so you just eat up to it.

Balanz learns your real metabolism

After a few weeks of logging and weigh-ins, adaptive targets replace the formula estimate with what your body actually does.

What you get

Built around Apple Health, not a food database.

Your health data stays yours

Balanz was built so that the sensitive part never leaves your iPhone.

  • โœ“Health data never leaves your device. Calories, weight, steps and workouts are read from Apple Health and stored locally โ€” they are never uploaded to our servers.
  • โœ“No account, no sign-up. Balanz uses an anonymous ID so nothing is tied to your name or email.
  • โœ“No ads, no data selling. We do not sell or share your information, and we never use health data for marketing.
  • โœ“AI features are opt-in. The weekly insight only sends anonymous weekly totals, and only after you agree. You can turn it off anytime.
