Notes on stress, sleep & calm
HRV vs Heart Rate: Which One Better Reflects Stress?
Heart rate measures beats per minute; HRV measures variation between beats. Both can respond to stress, but trends and context are more useful than isolated readings.
How to Lower Your Heart Rate When Stressed: A Gentle Reset
Slow breathing, reduced stimulation, and a few quiet minutes may help a stress-related heart-rate rise settle. Know when symptoms require urgent care.
How to Calm Down Fast: A 5-Minute Stress Reset

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.
