Sonno - Sleep Sounds

Most sleep sound apps give you fixed tracks. Sonno gives you the mixer.
Layer crashing waves with quiet rain. Add a French garden at dusk over a deep brown noise base. Drop in a desert wind, lower the crickets, raise the thunder. Sonno is built around one idea: in under a minute, you should be able to design the exact ambience that calms your mind — not someone else's idea of relaxing.

START WITH A SOUNDSCAPE
Begin from one of our hand-crafted scenes — French Garden, Ocean Calm, Desert Wind, and more — each combining looping samples with layered noise for a rich, seamless wall of sound. Or start from silence and build your own.

ADD, ADJUST, SAVE
• Layer additional samples onto any soundscape with a tap
• Adjust each sample's volume independently
• Mix multiple sounds together until the balance feels right
• Save your custom mixes and return to them any night

DESIGNED FOR SLEEP
• Seamless, non-looping playback so you don't notice the transitions
• Sleep timer with gentle fade-out so the sound doesn't jolt you awake
• Plays in the background — keep your screen off, your battery untouched
• Works with AirPlay, headphones, and your favourite Bluetooth speaker

WHY PEOPLE USE SONNO
• Falling asleep faster, especially in noisy environments
• Blocking out traffic, neighbours, or a partner's snoring
• Calming racing thoughts at bedtime
• Focus and study sessions during the day
• Relief for tinnitus and light sleepers
