## What is Murrona?

Fall asleep to a purr you can feel.

Murrona turns your iPhone's Taptic Engine into slow, body-like rhythms: a cat's purr, a resting heartbeat, a long breath, a train on the rails, ocean waves. No sound needed. No bright screen. No headphones.

Pick a rhythm, set a timer, tap "Start and dim the screen". The display goes black and the rhythm carries on. Hold your phone, or rest it on the bed beside you: the mattress carries the rhythm to your body.

Slow rhythms may stimulate the vagus nerve, which can help lower cortisol. Murrona is for comfort and relaxation; it is not a medical device.

FIVE RHYTHMS YOU CAN FEEL
• Purr — a warm, organic purr that breathes and varies like the real thing. Not a mechanical buzz.
• Heartbeat — a soft lub-dub at 40–100 BPM. "Settle" slowly eases the tempo over 15 minutes.
• Breathing — intensity rises and falls like a breath. Presets: Slow (4/6), Even (5/5) and 4-7-8.
• Train — a soft ta-dam on the rails at a pace you choose, with a gentle accent now and then.
• Ocean Waves — slow swells that never repeat exactly. Slide between calm and stormy.

MADE FOR THE DARK
• Always dark, built for dim rooms
• Dim mode: the screen goes fully black; one tap lights it up gently to show the time and controls, then it darkens again
• Sleep timer from 5 to 180 minutes with a soft fade-out
• Strength and speed set separately for every rhythm, and remembered
• Optional ultra-quiet sound layer that follows the haptics; mixes with your podcast or music
• Pauses when you leave the app and continues when you come back

GOOD TO KNOW
• iPhones vibrate only for the app in front, so keep the phone unlocked, ideally charging. Dim mode is made for exactly that.
• Needs an iPhone with a Taptic Engine (iPhone 8 or later). iPad has no haptic motor.
• Murrona is for comfort and relaxation. It is not a medical device and does not diagnose, treat or cure any condition.

SAFE BY DESIGN
• Heat guard: halves the strength when your iPhone gets warm, stops if it gets hot
• Battery guard: fades out below 10% unless charging
• The phone lies on top of the bed, uncovered. Never put it under a pillow, blanket or bedding, and never in a crib

FAIR AND PRIVATE
• Try it free: 10 minutes a day on 3 days
• One purchase unlocks everything. No subscription, no ads, no account
• Family Sharing included
• No tracking, no analytics. Nothing leaves your device
