From overwhelmed to exhale
Exhale turns heart data and your calendar into a calm you can actually act on.
Connect your watch
Exhale reads heart rate, HRV and sleep from Apple Health — one tap, no account needed.
See your stress score
A live 0–100 ring shows how your body is really doing right now, from calm to high.
Learn your triggers
Exhale links your calendar to your stress peaks so you can see what's quietly draining you.
Breathe it back down
Start a haptic breathing session and watch the number fall — calm you can actually feel.
Frequently asked questions
Does my health data ever leave my phone?
No. Your heart data and calendar are processed entirely on your device — nothing biometric is ever uploaded to a server.
Do I need an Apple Watch?
A watch gives the most accurate score, but Exhale works with any device that syncs to Apple Health — and it demos fully without one.
How does it know what stresses me?
It compares your stress peaks against your calendar. Recurring meetings, long days and packed afternoons rise to the top as your triggers.
What is haptic breathing?
Your phone gently vibrates in rhythm with each breath, so you can follow a calming pattern by feel — eyes open or closed.

Your stress, understood — and softened — right on your phone.
