01 · Understand
Your history, in perspective.
See how your heart rate variability compares with your own recent baseline. Explore trends over days, rather than treating one reading as a score.
Attune · iPhone, iPad & Apple Watch
Know your patterns.
Find your calm.
Make sense of your Apple Watch HRV, notice patterns in your days, and take a guided breathing break.
App Store release in preparation
A small daily ritual.
02 · Notice
Put your day in context.
Add tags and notes about sleep, movement, stress, and more. Explore what shows up alongside changes in your readings, without assuming a cause.
03 · Breathe
A break at your pace.
Follow a visual breathing guide for 5, 10, or 20 minutes. Choose your pace, sound, and taps, or practice from your Apple Watch.
No account. No analytics.
Attune processes your HRV and personal history on your devices. Health access is optional, and breathing practice works without it. You control exports and deletion.
A personal reference, not a diagnosis.
Apple Watch records HRV from time to time. Attune uses available Health readings; it does not measure HRV live, guarantee a new reading after practice, or provide medical advice.
