Your verdict before you unlock
Fits every athlete
Adapted to the way you train.
For the runner chasing a time.
Readiness before you lace up, pace and zones from your own thresholds, and age-graded PBs from the official WMA tables — so a 10k at 44 means something.
For the rider stacking long weekends.
Training load beside recovery, every climb and every hour in one place, and a week that can absorb a big Sunday without the Monday surprise.
For the swimmer who counts every set.
Distance, pace per 100 m and every set in context with the night before it — because the water only gives back what you absorbed.
For the lifter who trains by feel — and wants proof.
An honest verdict before you load the bar, heart-rate zones that tell a circuit from a commute, and a long-term picture of the work behind the numbers.
For the skier whose season never really ends.
Classic, skate or roller skis — the picture carries across the year. Zones from your own thresholds, load that remembers last summer, and a verdict that knows −12 °C costs you something.
For the yogi who recovers on purpose.
Keho reads the night, not the mat: HRV, sleeping heart rate and breathing against your own baseline, so a slow flow lands on the day your body actually asks for it.
Keho Coach coming soon
A coach that adapts to how you actually recover.
Keho learns your baselines and shapes the week around them — a verdict every morning, sessions that move when a night goes wrong, and a build that peaks when it matters.

Recovery, decoded
Recovery is part of the work.
Deep, core and REM — not just “asleep”. HRV against your own normal. A score you can trust. And a warning when your vitals drift together, often a day before you feel it.
- Sleep debt and regularity, understood across months, not just one morning.
- An overnight vitals check: resting heart rate, breathing, temperature and SpO2.
- Streaks that make room for rest. Consistency, measured honestly.

Integrations
Works with the watch on your wrist.
Keho is built on Apple Health. Whatever records your training, Keho reads it, keeps it on your iPhone and turns it into something you can act on every morning.
Apple Health.
Where it all comes together.
Every signal Keho uses lives in Apple Health — on your iPhone, under permissions you grant type by type, and take back just as easily.
- Sleep stages NIGHT
- 24/7 heart rate BPM
- HRV (RMSSD) MS

- Blood oxygen SPO2
Full Polar Flow sync

Sleep stages, 24/7 heart rate, breathing, SpO2, temperature — the data Polar Flow keeps to itself now arrives in Apple Health, automatically, every night.
Polar Flow → Apple Health
- Sleep stages — deep, core, REM
- 24/7 heart rate, not just workouts
- Breathing, SpO2 and temperature
- Sleep score · Nightly Recharge · cardio load

Private by architecture
Your health data stays yours.
Keho processes your biometrics on your iPhone, not on our servers. No profile to build. No health-data cloud to breach. Just the insight you asked for, from the data you choose to share.
- No account. Ever. Nothing to sign up for, because there is no server keeping a profile of you.
- Built on-device. Sync, statistics, readiness and every briefing are computed on the phone in your hand.
- Yours in Apple Health. Your data lives in Apple Health under permissions you grant — and can revoke — per type.
- Unreadable by design. Not a promise that could quietly change. There is no pipe from your health data to us.
A closer look
How athletes use Keho every day.
“The morning verdict is the first thing I look at. It has been right about my legs more often than I have.”
“Finally my Polar sleep stages and 24/7 heart rate are in Apple Health. Everything in one place, nothing in a cloud.”
“Imported six years of Polar history in one evening. The trends suddenly mean something.”
“Load against recovery, every day, without a subscription to a wristband. That is the whole pitch and it delivers.”
“The overnight vitals warning caught a cold two days before I felt it. I skipped the session and was fine by the weekend.”
“Calm, honest, no streak guilt. It tells me when not to train, which no other app has had the nerve to do.”
Common questions
Frequently Asked Questions
The details that matter before you download. Can’t find yours? A person reads every message.
Contact usWhat exactly does Keho do?
Keho turns the health and training data already on your iPhone into a clear morning readiness verdict and deeper statistics for every sport you do. With a Polar watch, it also brings key data Polar Flow does not send to Apple Health. Keho Coach, with adaptive plans and guidance, is coming soon.
Do I need a Polar watch?
No. Polar Sync is a major advantage for Polar owners, but Keho also reads the Apple Health data you choose to share. That can include Apple Watch, Garmin, Suunto, COROS, Oura and more. Coach will work from that same foundation when it arrives.
Which Polar devices work?
Any device that syncs to a Polar account: the Vantage, Pacer, Grit X and Ignite families, Verity Sense, and the H10 and H9 straps. Keho connects through Polar’s official API. No pairing. No Bluetooth setup.
Does my health data leave my phone?
No health data leaves your iPhone. Keho computes its statistics and readiness on-device, and your data remains in Apple Health and local app storage. There is no Keho account or server holding your biometrics.
Will Keho import my old history?
Yes. Polar’s live connection only reaches back about four weeks — but your Polar account can export everything it ever recorded, and Keho imports that export: workouts with heart rate and routes, sleep with stages, 24/7 heart rate, Nightly Recharge, years back. The import runs entirely on your iPhone and is part of Polar Sync. You don’t even need to connect — an export alone is enough.
How is this different from WHOOP or Oura?
Keho works with the watch you already own and processes your data on your phone rather than in our cloud. It gives you readiness and long-term trends now, then will add adaptive Coach features without requiring another device.
Do I have to take out a subscription?
No. Core statistics are free forever. Polar Sync starts with a free month and then renews yearly unless you cancel — or you can pay once instead, which never becomes a subscription. Prices are shown clearly in the app before you buy, and data already in Apple Health remains yours whether or not you continue with a paid feature.
How does the sync keep running?
Connect once. Keho syncs quietly in the background when iOS allows, overnight and whenever you open the app. It is designed to re-sync safely without creating duplicate entries in Apple Health.
Is there an Android version?
Not today. Keho is built around Apple Health and on-device processing, so it is available for iPhone only.
Is the coaching medical advice?
No. Keho is advisory and grounded in your own data. It is not a medical device and never a substitute for a clinician. When there isn’t enough data to be confident, it says so.
