About this app

Create your calm and drift into sleep with Nimbest.

Mix rain, distant thunder, fireplaces, forests, rivers, ocean waves, train ambience, airplane cabins, and more into a world that feels right for tonight. Start instantly with a relaxing built-in world, or describe a new soundscape and let Nimbest create it on your phone.

Designed for comfortable, uninterrupted sleep:

• Natural, sleep-safe soundscapes with softened harsh treble
• Independent volume controls for every sound
• Smart variation that reduces obvious repetition without changing your world
• One-off sounds such as thunder return at natural, adjustable intervals
• Sleep timer with a gentle fade-out
• Background playback and lock-screen controls
• Saved worlds remain available offline
• Rename, edit, remove sounds, or delete a world at any time

Private by design:

• No account required
• Your prompts and generated audio stay on your device
• On-device sound generation is downloaded only when you choose to create
• Existing and built-in worlds keep working without the generation model

Nimbest includes two complimentary creations. When those are used, you can choose to watch one short rewarded ad for another creation. Ads never interrupt sleep audio. A one-time Unlimited Worlds purchase removes the need for rewarded ads and unlocks unlimited creation.

Create your calm. Drift into sleep.
