Halo

Your health made simple

Halo turns what your band already measures into three clear scores, each measured against your own last 30 days. No AI coach, no noise: just how you're doing.

Coming soon to iPhone

Works with Fitbit · Apple Watch · Whoop

The Sleep tab: sleep stages through the night and heart rate by stage The Today tab: Recovery, Effort and Sleep rings, key numbers and the Balance chart The Health tab: every vital against your normal range

Three scores

Everything you need, at a glance.

Each score is measured against your own normal, not anyone else's, so a good day means good for you.

72

Recovery

How ready you are

Each morning, your heart rate variability and resting heart rate against your own last 30 days, with a quarter from last night’s sleep.

  • HRV
  • Resting heart rate
  • Last night
30

Effort

How much you’ve moved

Fills up from midnight: half your steps against your target, half your time in heart-rate zones, where harder minutes count for more.

  • Active minutes
  • Zones
88

Sleep

How well you slept

Time asleep against the sleep you want, with your deep and REM sleep, how calm the night was and how steady your bedtime is.

  • Deep & REM
  • Bedtime

Insights

Your workouts, read against everything else.

Halo sets your activity beside your sleep, recovery and steps over the same weeks, to show what actually moves the needle: your big days, what hard sessions cost you the next morning, and how you sleep after training.

Fitness insights: workouts this month, favourite activity, big days, and sleep and steps on workout days

Made for you

Simple on the surface. Deep when you want it.

Every vital against your normal

HRV, resting heart rate, breathing, blood oxygen and skin temperature, flagged only when they move the wrong way.

A sleep bank, not just a score

The sleep you owe or have in hand over the week, against the amount you choose.

Workouts that mean something

Each session against your others, how you slept after it and how much it moved your week.

Yours to arrange

Move and hide cards, pick a colour set, light or dark, and an app icon to match.

Private by design

Your data stays on your iPhone.

No account, no cloud, no analytics, no ads. Halo reads your band with read-only access and works everything out on your phone.
