BIONNY, how does it work?
Wear it 24/7
Bionny is always ready, on your wrist day and night. Lightweight, screen-free and with 30 days of battery life, you never lose a second of data.
Analyses your body data
In the background, Bionny tracks your blood pressure, heart rate, HRV, sleep, stress and blood oxygen — turning every moment into clear health data, no screen required.
Understand your body
Open the app to see your health trends laid out simply: what's steady, what's shifting, and how your sleep, stress and recovery connect.
Change your habits
With a clear picture of your body over time, you can see what actually moves the needle — and build the habits that help you feel and age better.
A health tracker with no screen, no distractions
No screen means no pings, no notifications, no reason to glance at your wrist. Bionny tracks your heart, sleep, stress and blood pressure quietly in the background — so you get a full picture of your health without the noise of a smartwatch.
More ways to understand your body.
Track more. Charge less.
Most health trackers need charging every few nights. Bionny runs for up to 30 days on a single charge — so your blood pressure, sleep and heart rate data never has a gap.
Blood pressure tracking, right from your wrist
Picture checking in on your blood pressure as easily as the time — no cuff, no clinic, no second-guessing. Bionny quietly follows your trends day and night, so instead of a single reading at the doctor's, you see the full story: how your mornings, your meals and your stress really affect you.
Bionny provides blood pressure trend data for general wellness and is not a medical device.
Take a closer look.
Zero distractions
No screen, no pings, no notifications — just quiet health tracking that stays out of your way.

Up to 30 days of use on a full charge, and up to 3 days from just a 10-minute top-up.
All-day comfort
Skin-safe woven nylon, light enough to forget you're wearing it — day and night.
Water & dust resistant
Rated 1ATM and IP68: safe in the pool or ocean down to 10 metres, and fully sealed against dust.
Four colours to choose from
Pick your band in black, blue, orange or pink to match how you move.
Own your Bionny journey
From the moment you put Bionny on, it starts tracking your key metrics — sleep, heart rate, HRV and stress. Calibrate once against a baseline reading, and your blood pressure trends start building, day and night.
Two weeks in, your sleep score and heart rate have a baseline to compare against. The patterns start to show — how meals, stress and rest move your blood pressure, and what helps you sleep more deeply.
Your HRV trend now reflects how well your body recovers, so you know when to push and when to ease off. Your daily stress averages reveal what triggers your spikes and how long they last.
A full month of continuous data — all on a single charge. Your baseline is set, your trends are clear, and Bionny can even estimate your biological age, so you see exactly how your habits are paying off.
