For the stressed
Always tired? Your body knows why.
With an Apple Watch, ExaHealth monitors your stress in real time, all day — HRV, autonomic strain, sleep and recovery — showing exactly what’s draining you, moment by moment. No watch yet? Your phone camera gives an on-demand spot reading.
- “Your reports are normal” — but you don’t feel normal
- You crash by 4 PM and can’t explain why
- Every app tells you to “relax more”. None shows you the cause.
Built for exactly this moment
Priya’s reports kept coming back “normal”. Her mornings didn’t agree.
Her signals are checked against her own baseline — not a population average. When resting heart rate and HRV drift together for days, she has a concrete pattern to show her doctor instead of “I’m just tired.”
Her 7-day pattern
Resting HR+3 bpm vs her usual
HRV−4 ms vs her usual
Sleep debt1.2 h this week
A pattern worth a conversation — printed for her next visit. No wearable? The phone camera can read HRV too.
All-day, real-time stress monitoring
With an Apple Watch on your wrist, ExaHealth watches your stress continuously — not once a day. Heart rate is read by state across the whole day, so you can see the exact moment your body spiked (9:15 AM, 126 bpm) and when it finally settled back to baseline.
- Continuous heart-rate-by-state, all day (Apple Watch)
- Your biggest spike, pinpointed to the minute
- Stress vs recovery vs activity, colour-coded
Stress you can measure, not guess
Your stress score is built on the Baevsky Stress Index — a validated 0–100 measure of autonomic strain — drawn against your healthy range and overstrain threshold, with HRV (RMSSD) compared to your own baseline.
- Autonomic strain vs a healthy-range band
- HRV vs your personal baseline — not population averages
- “Load is building” alerts when HRV drops
What charges you, what drains you
Body Battery shows exactly what recharged you — deep sleep, calm periods — and what drained you — stress, hard activity — with an overnight-recovery score for how well you actually reset.
- “Charged you” vs “drained you”, ranked
- Overnight recovery scoring
- Peak and low energy for each day of the week
Where your day actually goes
A zone distribution splits every day into Sleep, Recovery, Neutral, Stress and Activity — so you can see, honestly, how much of your day is spent under strain versus genuinely recovering.
- Sleep · Recovery · Neutral · Stress · Activity split
- Daily breakdown and a 30-day average
- Spot the days you never truly recovered
Watch the trend over weeks
Stress Impact charts your daily stress percentage across 30 days — total stress time, recovery minutes and your calmest day — so you can tell whether life is getting lighter or heavier.
- Daily stress % across the last 30 days
- Stress time vs recovery time
- Your calmest and most stressful days flagged
Fix tonight, feel it tomorrow
Sleep guidance computes your sleep need and debt, then tells you tonight’s ideal bedtime and optimal wake time — small changes, compounding energy.
- Sleep need, debt and balance tracking
- Ideal bedtime and wake-time guidance
- Restfulness: tossing, turning and noise around you
A spot check, no watch needed
No Apple Watch? Place your fingertip on the camera and get a point-in-time HRV reading in about a minute — a quick stress and readiness snapshot from the phone already in your pocket. (Continuous, all-day tracking needs a watch.)
- On-demand camera HRV (PPG) — a single reading
- Signal-quality scoring so you can trust it
- Upgrades to continuous once you add an Apple Watch
What you’ll need
Works with Apple Watch
These live-tracking features — activity, stress and stress load, readiness, body battery and heart rate — sync continuously from an Apple Watch.
The bigger picture
Sometimes “tired” is stress. Sometimes it’s iron.
ExaHealth connects your energy data to your labs — thyroid, iron, vitamin D, blood sugar — in one Health Score. So you stop guessing which kind of tired you are.
