## What is Stilla?

Stilla — Swedish for "calm" — is resonance breathing, simplified.

Most breathing apps make you follow a fixed rhythm. Stilla finds YOURS.
Everyone has a resonance rate — the breathing pace, somewhere between 4.5
and 6.5 breaths per minute, where heart and breath fall into step and the
body's relaxation response engages most deeply. Connect a heart-rate sensor
and Stilla discovers your rate session by session, then keeps you there.

BREATHE
• A calm, luminous guide — a blooming flower, drifting stars, a tidal pool,
  or lakeside reeds swaying with your breath
• Resonance, Box (4-4-4-4), and 4-7-8 patterns — at their classic tempo or
  yours, with per-pattern presets and fully custom timings
• Adaptive pace: in resonance sessions, Stilla can retune the rhythm live,
  epoch by epoch, toward the rate your heart follows most strongly
• Any session length from 1 to 60 minutes
• Gentle haptics — holds get their own distinct cue — and an adaptive
  soundscape that follows your breath
• Sessions continue on your Lock Screen and Dynamic Island
• Apple Watch taps guide each breath from your wrist

UNDERSTAND
• Heart-breath sync, measured — spectral coherence between your heart
  rhythm and your breathing
• Every pattern read on its own physiological terms: sync and heart-rhythm
  swing for Resonance, heart settling for Box and 4-7-8
• Post-session HRV insight: RMSSD, heart-rate swing, and signal quality
• Trends over weeks: every session charted, any metrics overlaid
• One honest finding at a time — like "your sync runs higher after 19:00"
• Practice rhythm, pattern comparison, milestones, and streaks

PRIVATE BY DESIGN
• No account. No analytics. No network access at all.
• Your data lives on your device and, with your permission, in Apple Health
• Sessions log as Mindful Minutes

WORKS WITH
• Apple Watch (heartbeat intervals during sessions)
• Bluetooth heart-rate straps (Polar, Garmin, Wahoo, and any standard
  BLE heart-rate monitor)
• Works fully without any sensor — guidance, patterns, and streaks
