About this app

SonoLune is a complete calm environment for your phone: sleep sounds and white noise, ambient focus music, a warm night light, and a quieter screen, all in one continuous system, not a single-trick app.

Not just a timer. Not just a white noise app. Not just a blue light filter. Everything is optional and off until you choose it.

No ads. No account. No third-party trackers built in. Core use works offline.

FOCUS SESSION
• A calm ritual, not a bare timer: name what you sit down to do and it is read back at the close
• Choose a room (Violet Field, Warm Study, Deep Harbor, Paper Dawn, Clear Glass) that recolours the screen and matches your light and sound
• Optional settling breath, companion light, and soft start and end chimes
• Carry your Ambient Field into Focus; finishing is a slow dawn with no streak to chase

PRESENCE FIELD
• A visual detox, a field not a fence, the calm answer to app blockers
• As your atmosphere deepens, a warm quiet draws over the screen and the apps that pull at you fade toward hardly-visible
• Choose the few apps it is for; always tap-through, always one tap to lift

LUNAR ARC

ONE CALM SYSTEM
Use one app instead of a separate sleep-sound app, white noise app, focus timer, night filter, blue light filter, and relaxation tool.

PRIVACY-FIRST
• No ads
• No account required
• No streak pressure or gamified loops
• No third-party trackers built in
• Core use works offline

ACCESSIBILITY SERVICE USE
Optional. If you turn on full-system Light coverage, SonoLune uses Android AccessibilityService only to extend the light tint onto the lock screen and notification shade. It never reads screen content, notifications, text, passwords, or personal data, and is never used for tracking or ads. You can use SonoLune fully without it and turn it off anytime.

Built slowly. Shaped with restraint. Guided by calm.
Enter the environment.

Ratings and reviews

NOTE: As of 1.7.0 my gripe does NOT exist! it was updated for smoother listening. Original review: I really like SonoLune. I use it for work, my alarm, and pretty much anything for focus. My only gripe is when the sound reaches the end, it resets and there is a noticeable shift/restart of the sound instead of a gradual crossover so to speak. Otherwise, absolutely love. 5/5.

Sonolune is a... different beast than the usual white noise or calm/sleeping relaxation apps. Its developer called it a 'shaped environment combining light, sound and the quiet in a field.' There is quite a bit to explore right off the bat and there are plentiful features to unwrap. There is a nifty timer that helps you to focus on a specific task for a set period. You can also control the lighting of your device to assist in setting moods. It is a big suite of mood-shaping tools.

I enjoy using SonoLune as it is ad-free which helps me focus on the sound without distractions. I also like that it works offline ensuring reliability even without Wi‑Fi. The soundscapes are truly calming and I can combine them to suit my mood. Overall this app provides a calm, distraction-free and user-friendly experience.

What’s new

SonoLune 2.0, the biggest step since launch.

Meet the Presence Field: a new room where your screen and sound settle as one. A gentle visual detox that quiets the apps pulling at you. A field, not a fence.

Focus is now a calm ritual with rooms you match to your light and sound. Light gains a Kindle-paper finish and can follow your own sun. Night arrives on your timing. A new Help and Guides hub meets you in every suite.

Optional and off until you choose it. The calm core stays free.
