Sleep sounds that fade with you
ONDA Sleep is a dark, slow ambient soundscape composed live on your phone for bedtime. A low, sustained harmony with almost no events thins and darkens over the first half hour, optionally with ocean, rain or wind underneath. Set the timer and it fades out on its own, even with the screen off. It never loops, so there is no seam to notice in the night.
What do ONDA sleep sounds sound like?
Deep, unhurried chords in a soft room, with very few notes and nothing that rises suddenly. Over the first thirty minutes the music gets darker and quieter, so it asks less and less of you. Night Current, Midnight Drift and Lunar Nocturne are the three soundscapes in the Sleep space.
Sleep sounds without a loop
Many sleep sounds are short recordings played on repeat. ONDA composes as it plays, so there is no recording to restart and no gap or click when it would have looped. The sound keeps its character all night while the details keep changing.
Built for the bedroom
- A timer that fades out over a minute instead of stopping abruptly.
- Lock-screen controls and playback with the screen off.
- No ads, no notifications, nothing that lights up in the night.
- Works offline, so it plays in flight mode.
- Optional nature beds: ocean, rain, wind, air or hearth.
Tips
Keep the volume low, set the timer and put the phone face down. If you wake in the night, start it again: it is a new composition every time.
Not a treatment for sleep problems. If you often struggle to sleep, talk to a healthcare professional.
Questions
Can I fall asleep with it playing?
Yes. Set the timer for 30, 60 or 120 minutes and ONDA fades out on its own, even with the screen locked. Or leave it running; it never repeats.
Do I need headphones for sleep sounds?
No. Everything is designed for an ordinary phone speaker. Headphones are only required for the optional binaural mode.
Does ONDA work offline?
Yes. ONDA composes the music on your device instead of streaming it, so after the first visit it keeps working without a connection. You can add it to your home screen and it plays with the screen locked.
Is ONDA free?
Yes, during the preview. You can listen for 10 minutes straight away with no sign-up, then create a free account with just an email address to keep listening.
Is ONDA a medical product?
ONDA is music for wellbeing, not a medical device. It does not treat any condition, and everyone experiences sound differently.
