A clear summary to take to your doctor.

Onni Health will turn your own check-ins, HRV and symptom history into a one to two page summary you can take to your GP or specialist, so the appointment starts from what you have actually recorded.

Choose the dates it covers
Say who it is for: your GP, a specialist or another clinician
Give your reason for the appointment, in your own words
Review it first and untick anything you would rather leave out
Your data and trends, reported as facts. It never recommends tests or treatments

This summary is generated from patient-reported and wearable data and is not a clinical diagnosis.

HRV with your phone camera

Measure your HRV with just a fingertip.

No wearable, no chest strap. Rest a fingertip over your phone's rear camera and flash for one minute, watch your pulse wave appear live, and get your heart rate variability and heart rate.

    Cover the camera

    Rest the pad of your fingertip gently over the rear camera and the flash. The app shows you exactly where.

  2. The Onni Health app measuring, with a live pulse wave, a heart rate of 73 and a one minute timer

    Watch your pulse live

    Your pulse wave draws in real time with your heart rate beside it, while a one minute timer counts down. Just breathe naturally.

  3. The Onni Health app result screen: HRV of 48 milliseconds, 72 beats per minute and good signal quality

    See your result

    Your HRV (RMSSD, in milliseconds), heart rate and signal quality. A reading that is not clear enough is never saved.

HRV measurement is part of the Onni Health mobile app for iPhone and Android.

HRV biofeedback
Coming soon

Slow your breathing. Settle your body.

HRV biofeedback is slow, paced breathing at around six breaths a minute, guided by the app. Breathing at this steady pace can help your body shift towards its rest and recover state.

Good questions

The things people ask first.

Is Onni Health a medical device?+

No. The Onni Health app is a wellness tool only. It does not diagnose, treat or give medical advice; it helps you track and understand your own data. Mend Clinical Care is a separate UK service, and our clinicians only see your data if you choose to share it.

Can I cancel whenever I want?+

Anytime, in one tap, no questions asked. Your membership runs to the end of the month you've paid for.

Is my journal really private?+

Yes. It's encrypted, never stored in plain text, never shown to admins, and never used to train models. Not even we can read it.

Will my doctor understand the AI summary?+

Yes. It's plain English describing your own trends, with nothing clinical to decode, so it is easy to show at an appointment.

Do I need a wearable?+

No. Onni Health measures HRV through your phone camera during the programme, so there's nothing extra to buy.

Ready when you are

One gentle check-in at a time.

Onni Health meets you where you are and helps you move forward with clarity and compassion, never pressure.
