SonoLune: Sleep Sounds & Focus

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.

WHY PEOPLE INSTALL SONOLUNE
• Sleep sounds and white noise for calmer bedtimes
• Ambient focus music for study, reading, and deep work
• A warm night light and blue light filter for evenings
• Eye comfort and screen breaks for long phone use

SOUND ATMOSPHERE
• Layer rain, wind, forest, ocean, room tone, and soft textures into your own soundscape
• Curated fields: Forest Rain, Library Rain, Tide Lantern, Low Storm, Quiet Room, Deep Rest, and more
• NeuroLayers add binaural tones and stereo width for focus and rest
• Atmosphere Depth shapes warmth, room space, and layer presence from one calm control
• Compose, name, and save soundscapes to return to later

LIGHT SUITE
• Warm Light on a true colour-temperature curve, from warm-white to deep candlelight
• Blue light reduction and screen dimming for night and long reading
• Paper Matte with a tactile e-paper grain, like reading on a Kindle
• Colour Veil to tint the screen toward a softer mood, and Living Field for gentle motion
• One-tap Settle, saveable presets, and coverage to the very edges of the screen

NIGHT ENVIRONMENT
• A deeper night space with an intensity slider and calm depth presets
• Auto-deepen through the evening, and choose how gently Night arrives
• A screen that can follow your own sun: local sunset and sunrise, worked out offline with no GPS
• Schedule Night for a steady wind-down rhythm

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
• Uses Usage Access only to know which app is in front, never to read your screen

MIND SUITE
• Space and Living Moments for light and atmosphere you can return to
• Suggested Focus Moments for a soft start, with Moment Memory to keep your tuning
• Mind Programmer for quiet, gentle affirmations

LUNE CIRCLE
• Lune Guard, guided eye care: 20-20-20 breaks, blink and far-focus cues, with optional reminders outside the app
• Lune Field, a living Night wallpaper: shape the sky, moon, horizon, and stars

LUNAR ARC
• Let SonoLune meet you at the right time: schedule Night, Sound, Light, Mind, and Focus

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.
