Attune: HRV & Breathing

Know your patterns. Find your calm.

Attune helps you understand your heart rate variability (HRV), notice patterns in your days, and make time for guided breathing. Built for iPhone, iPad, and Apple Watch, it keeps your personal records on your devices.

MAKE SENSE OF YOUR HRV
Explore readings from Apple Health, follow your personal baseline, and look at trends over weeks and months. Clear context helps you understand your own history without reducing your day to a readiness score.

NOTICE YOUR DAILY PATTERNS
Add simple tags and private notes. Compare your history across different routines and see observations as useful context, not proof of cause and effect.

TAKE A BREATHING BREAK
Choose a 5-, 10-, or 20-minute guided practice. Find a comfortable pace, choose your guide and cues, and pause when you need to. Practice on your phone or follow the rhythm on your wrist with Apple Watch.

YOUR HEALTH, YOUR CHOICE
Apple Health access is optional. You can practice breathing without connecting Health and separately choose to save completed practices as Mindfulness sessions. Attune does not take live HRV measurements or promise a reading after practice.

PRIVATE BY DESIGN
No account, ads, or tracking. Your history, notes, and preferences stay on your devices. Set a local reminder, export your records, or delete local app data from Settings.

Attune is for personal wellbeing and education. It does not diagnose conditions, provide treatment, or replace professional medical advice.
