SonoLune: Calm Environment

Most apps on your phone are built to hold your attention. SonoLune is built to hand it back.

It is one environment, not a folder of features. The light warms and dims below what Android allows. The sound becomes an atmosphere you layer yourself. The apps that pull at you go quiet. And nothing switches itself on.

THE LIGHT
• A screen dimmer that goes below your phone's own minimum, for reading in the dark
• Warm Light on a true colour-temperature curve, down to candlelight
• Blue light filter and a warm night light for the evening
• Quiet Veil softens glare, Colour Veil tints, Living Field adds motion
• Paper Matte gives the screen an e-paper grain, like a Kindle
• The screen dimmer and the blue light filter can carry across the whole phone

THE SOUND
• Layer rain, wind, forest, ocean and room tone into a soundscape of your own
• Curated fields: Library Rain, Tide Lantern, Low Storm, Deep Rest
• Sleep sounds and white noise for bedtime, ambient focus for study and work
• NeuroLayers add binaural tones and stereo width
• Atmosphere Depth shapes warmth, room space and presence from one dial
• Compose, name and save soundscapes

THE NIGHT
• A deeper night space with its own intensity and presets
• Auto-deepen through the evening at the pace you set
• A screen that follows your own sun: local sunset and sunrise, offline, no GPS

THE QUIET
• Presence Field is a visual detox — a field, not a fence
• As your atmosphere deepens, a warm quiet draws over them
• Choose the few it is for. Always tap-through, one tap to lift
• Uses Usage Access only to know which app is in front, never to read it

THE FOCUS
• Name what you sit down to do. At the close it is read back to you
• Five rooms: Warm Study, Deep Harbor, Paper Dawn, Clear Glass, Violet Field, each recolouring session, light and sound
• Carry your Ambient Field in with you
• Optional: a held breath before it begins, a lamp beside the timer
• Pause and it waits, breathing. At the end nothing is owed — no streak, no next session

THE QUIETER CORNERS
• Living Moments save a light and atmosphere together
• Lune Guard: 20-20-20 breaks, blink and far-focus cues, anywhere
• Lune Field, a living Night wallpaper: shape the sky, moon, horizon, stars
• Lunar Arc schedules Night, Sound, Light and Focus around your day

ONE APP, NOT SEVEN
In place of a separate screen dimmer, blue light filter, night light, sleep sounds app, white noise app, focus timer and app blocker.

WHAT SONOLUNE REFUSES
• No ads. Not now, not later.
• No account. It never asks who you are.
• No third-party trackers built in.
• No streaks, no badges, no notifications asking you to come back.
• Nothing switches itself on. Every part stays off until you choose it.
• Core use works offline.

HOW IT IS PAID FOR
SonoLune is made by one person, and there is no advertising to sell — so nothing in it needs to hold your attention.

Free: the screen dimmer, the blue light filter, dimming below minimum, Quiet Veil, Colour Veil, the core sound layers, focus sessions, Night and the Presence Field.

An optional one-time supporter purchase opens Paper Matte, the Living Field, saved soundscapes, Atmosphere Depth, NeuroLayers and deeper Presence. A monthly patronage covers the Lab sessions and packs that keep arriving.

Neither is required. Nothing expires, nags, or degrades if you never pay.

WHO THIS IS NOT FOR
If you want one slider and nothing else, there are simpler apps and some are very good. SonoLune takes a few minutes to set up before it becomes yours. That is the trade, and the point.

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 carefully. Shaped with restraint. Yours to make quiet.
