She peeks out
Every few minutes Mia drops down from the notch for a quick check-in. She skips it while you're on a call, in a Focus, or away from your desk.
Coming soon for Mac
A little friend who lives in your notch.
Every few minutes Mia peeks out of your MacBook's notch, looks at you for 30 seconds while you keep working, and tells you what your heart rate, HRV and stress score read, against your own usual.

How it works

A check-in you barely notice

30 seconds, you keep working
Each heartbeat changes the colour of your skin, ever so slightly. Mia reads it through your camera with Nervotec's camera heart sensing while you carry on typing.

She tells you what she read
Heart rate and HRV, each with a confidence band. After 10 clean scans over 5 days she knows your usual and adds a stress score.
What she reads
Your numbers, against your usual
Heart rate
Beats per minute, with a band that shows how sure the reading is.
Heart rate variability
The tiny variation between beats. Mia only shows it when the pulse is steady enough to trust.
Stress score
0 to 100 against your own usual: 50 is your usual and 32–68 your usual range. It arrives once your baseline is ready.
Still learning? From your third scan Mia shows today versus yesterday. No comparisons with other people, ever.
Higher than usualjust now
Your HRV dropped
Your HRV reads lower than usual, and your stress score reads higher than usual. A short break is a reasonable call.

A 30-second snapshot, not a verdict.
One suggestion a day at most, and only outside your usual range.
She mirrors you
Smile, and she smiles back
Look a little down, and she notices. It's how Mia stays good company on long days. She notices your expression only during a check-in, and nothing about your face is kept.
She helps
Small breaks, at the right moments
Breathe
One slow minute at six breaths a minute, with Mia breathing along.
Stretch
After 50 minutes of sitting, Mia stretches and invites you to do the same.
Walk
After a couple of hours at the desk, a short walk. Five minutes is a nice reset.
Pomodoro
Focus rounds with breaks built in. Mia naps in the notch while you focus, and nothing interrupts a round.
Never in your way
Quiet by design
Mia lives in space your Mac already gives up to the camera: no Dock icon, no windows to manage. When she has nothing to say, the notch is just the notch.
- Skips check-ins while another app is using the camera, like a call
- Stays quiet in Focus and Do Not Disturb
- Waits while you're away or your screen is locked
- Hidden from screen sharing and recordings
- At most one suggestion a day from your readings
- Pause her for an hour, or until tomorrow, from the menu bar
Privacy
Your readings stay yours
Video is never recorded
The camera is on only during a check-in, and the light is on while it is.
Stored on your Mac, encrypted
Your readings are stored on your Mac, encrypted with a key kept in your Mac's Keychain.

No face template and no expressions. Only the numbers from each check-in.
