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.
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.
