For Apple Watch owners
Your Apple Watch ECGs, turned into a heart-health timeline.
Every ECG you record captures your heart's rhythm beat by beat. Apple Health shows them one at a time. Daibeats measures your heart rate and heart rate variability in every recording, checks its quality, and shows how they change over time.
- Analysed on your device. Nothing is uploaded.

All your ECGs in one view
Heart rate and heart rate variability (HRV) for every recording, on a timeline and by time of day.
Only trustworthy recordings count
Each ECG is graded. Recordings spoiled by movement or loose contact are shown but kept out of your trends.
A summary in plain language
Claude, Anthropic's AI model, explains what your numbers show and what can affect them. Coming soon
Why heart rate variability?
Your heart doesn't beat like a metronome. The small changes in time between beats, called heart rate variability, reflect how your nervous system regulates your heart. HRV tends to drop with stress, poor sleep and illness, and rise with fitness and rest. It's most useful compared against your own baseline, which is why a timeline matters.
For people living with diabetes, long periods of high blood glucose can affect the nerves that regulate the heart, and HRV is one of the measures doctors and researchers use to look at this. Daibeats doesn't diagnose anything; it helps you keep a clear record to discuss with your doctor.
Import your ECGs from Apple Health
- On your iPhone, open the Health app and tap your profile picture (top right).
- Tap "Export All Health Data", then Export. It can take a few minutes.
- Get
export.ziphere. AirDrop or save it to your computer, or open this page in Safari on your iPhone and choose it from Files. - Choose the file below. Daibeats reads only the ECG recordings inside it.

Private by design. Your export is read inside this browser tab. Your ECGs, your health data and the name and date of birth Apple includes in each file never leave your device. Closing the tab clears everything.
Your ECG timeline
These labels come from the ECG app on your Apple Watch, not from Daibeats.

Glucose insights from your ECG
Daibeats is researching how ECG signals can be used to estimate blood glucose without a finger-prick. It isn't available yet and will only be offered after clinical validation and regulatory approval.
Join the waitlist to hear when it's ready →Not a medical device. Daibeats ECG Insights is for information only. It does not detect heart conditions and must not be used for diagnosis or treatment decisions. If you have symptoms or a concern about your heart, contact your doctor.
Tested against expert-annotated heartbeats
Daibeats' beat detector found 100% of 1,140 heartbeats marked by experts in three five-minute recordings from PhysioNet's MIT-BIH Normal Sinus Rhythm Database, and 99.7–100% of its detections matched an expert's beat. Heart rate variability computed from our beats matched the same calculation on the experts' beats within a few percent. Each recording is then graded for quality, because a wrist ECG is easily disturbed by movement.
