About this app
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 No subscription required to use the core mixer.
