SOS PANIC BUTTON

━━━━━━━━━━━━━━━━━━━━━━━━━━━

One tap on the home screen launches an immediate calming session.

No mood check-in. No setup. No tutorial. For panic attacks at the

airport, anxiety before a presentation, or any moment your nervous

system needs help right now. Always free.

━━━━━━━━━━━━━━━━━━━━━━━━━━━

SEE YOUR HEART RATE CALM DOWN

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Place your finger on the rear camera before and after a session.

Coheran measures your heart rate using PPG — the same tech as an

Apple Watch or Fitbit, no extra hardware required — and shows you

the exact drop. Honest biofeedback, not vibes.

━━━━━━━━━━━━━━━━━━━━━━━━━━━

GUIDED VOICE OR FULLY SILENT

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Three voice options — Calm, Warm, Bright — guide your inhale, hold,

and exhale. Prefer silence? Switch to haptic-only mode and Coheran

guides you with gentle vibrations. No background music, no sleep

stories, no wellness coach lectures.

━━━━━━━━━━━━━━━━━━━━━━━━━━━

STREAKS THAT FORGIVE

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Build a daily breathing habit with streaks that don't punish you for

one bad day. Earn a streak freeze each week (capped at three) that

auto-applies when you miss. Habit-forming, guilt-free.

━━━━━━━━━━━━━━━━━━━━━━━━━━━
