About this app

Focus deeply, soften your screen at night, and shape a quieter digital space.

SonoLune brings night light, white noise, and focus into one continuous system — designed for deep work, evening wind-down, and intentional screen time. Use focus sessions with calm light and ambient sound, reduce screen glare at night, and let the environment adapt as your day moves toward evening.

Nothing starts automatically. You decide when your environment changes. No ads. No tracking. No pressure.


Focus Timer Sessions for Deep Work

Time-bound focus sessions designed for deep work, study, or evening routines. Sessions remain stable even when switching apps. When a session ends, your previous environment restores cleanly.

No ghost resumes. No unexpected playback.


Ambient Sound, White Noise & Sleep Sounds

Layer ambient sound and white noise for a steady background:

• Rain
• Wind
• Forest
• Ocean
• Fire

Sleep sounds and focus sounds designed to layer without clashing. Up to three layers at once. Sound evolves gradually and never resumes automatically after interruption.


Night Light & Blue Light Reduction

Designed for evening use and long screen hours:

• Warm night light overlay
• Blue light reduction
• Screen dimming below standard limits

Each adjustment shapes the entire visual environment without altering your device's brightness controls. Ideal for bedtime routines, late study sessions, and relaxation before sleep.


Predictable by Design

Light, sound, night mode, and focus work as one system. After interruptions or restarts, the environment restores safely — sound never resumes automatically.

Built for consistency across sessions.


Digital Wellness Without Pressure

No ads.
No data collection.
No streaks.
No gamification.

Independent. Calm-first. System-level.

Designed for people who value focus, rest, and intentional digital use.
