## What is Tranquil?

Tranquil turns your iPhone into a bedside sound machine. It looks and works like the real thing: turn the dial to pick a sound, press the big button in the middle to play, and use the large buttons on the front for volume and the sleep timer.

No menus to learn, no accounts to create, and no ads. Just press play and rest.

SIMPLE TO USE
• One big button to start and stop the sound
• Large Quieter and Louder buttons
• Clear, easy-to-read text
• Remembers your favorite sound and volume for next time

TEN SOOTHING SOUNDS
• White Noise
• Brown Noise
• Pink Noise
• Light Rain
• Heavy Rain
• Rain on Window
• Ocean Waves
• Box Fan
• Ceiling Fan
• Womb Sounds, to help settle babies

Swipe sideways to turn the dial, or tap any sound to play it. The light ring glows in a different color for each kind of sound.

Every sound plays at the same volume, and changing sounds fades gently from one to the next, so switching won't startle a sleeping baby.

SLEEP TIMER
Press the Timer button to choose 30 minutes, 1 hour, 2 hours or 8 hours. A light on the front shows which one is on. When time is up, the sound fades out gently instead of stopping suddenly.

PLAYS ALL NIGHT
• Sounds play continuously until you stop them or the timer ends
• Keeps playing when your screen is locked
• Start and stop from the Lock Screen or Control Center
• Works without an internet connection

PRIVATE BY DESIGN
Tranquil doesn't collect any information about you. There's nothing to sign up for and nothing to buy.

GOOD FOR
• Falling asleep and staying asleep
• Masking snoring, traffic and noisy neighbors
• Helping babies and children settle
• Naps, reading and quiet time
