Know how recovered you are, how you slept, and what today can take. From the wearable you already own, with nothing leaving your phone.

Early access for iPhone and Android.

Today: energy, stress and a one-sentence suggestion

Health: body metrics against your own usual

Sentences first. Numbers second.

Most health apps hand you a wall of figures. This one tells you how you slept and how ready you are in plain words, then shows the number behind it, always compared with your own normal and never a stranger's.

Your night, drawn as a dive.

Awake is the surface. The line sinks through REM and light sleep to deep, and comes back up. Drag across it to read any moment.

Train when your body says yes.

Start a workout on your phone and your strap's heart rate drives live zones, a satellite map of your route, and a share picture of your session made from your own photo. It stays with you unless you post it.

A live run: satellite map, distance, pace and heart rate zone

Sleep, properly.

Day, week, month and six months. Floating bars for every night, the vitals measured while you slept, and a bedtime for tonight worked out from what you owe.

Questions

Do I need an account?

No. There is no sign-up and no cloud. Your data lives on your phone and you can export or delete it any time.

Which devices work?

The Amazfit Helio Strap works today over Bluetooth. On iPhone you can also bring in sleep and heart rate from Apple Health, and on Android from Health Connect, so an Apple Watch or a Galaxy or Pixel watch can sit alongside the strap without mixing the two.

Will my scores match the Zepp app?

No. The scores use our own model, written out in plain words in the open source repository, compared with your own usual rather than a stranger's.

Is this medical advice?

No. Recovery, sleep and the other scores are estimates for personal insight. If a reading worries you, talk to a health professional.

What does it cost?

Early access is free while we test. A paid tier for long history and extra tools is planned; the basics and your own data export will stay free.

We are testing with a small group before the stores. Leave your details and we will send an invite.
