About this app

Struggling with a blindingly bright screen during night driving?

Many Android devices and aftermarket Chinese Android Head Units (AHUs) have a high minimum hardware brightness level that remains too bright for dark cabin environments. DashDim solves this by creating a highly-customizable, system-level software overlay that dims your display beyond normal system limits.

Drive safer and reduce eye strain with fully automated, context-aware dimming!

✨ CORE FEATURES:

• Context-Aware Dimming Modes:
1. Headlight Sync (For Car Head Units): Instantly dims the screen when you turn on your headlights, listening directly to your car MCU's backlight broadcast signals.
2. Smart GPS Sunset/Sunrise Auto-Dim: Uses an offline, math-based astronomical algorithm to calculate your local sunset and sunrise times. Dimming starts automatically at dusk and ends at dawn.
3. Manual Time Scheduling: Set a custom window (e.g., 20:00 to 07:00) with interactive pickers to schedule screen dimming. Supports crossing midnight.
4. Constant Manual Overlay: Disable automatic triggers and use DashDim as a constant manual screen filter set to your exact opacity preference.

• Physical Backlight Dimming (Optional Root required):
Directly dims the physical LED backlight of the screen by writing to kernel sysfs nodes. True hardware dimming reduces actual screen power consumption and provides a perfect dark cabin environment without glowing black software pixels. Features a built-in 3% safety floor to prevent completely blacked-out screens.

• Reverse Camera Safety Bypass:
Safety comes first. DashDim monitors when your vehicle is shifted into reverse and instantly removes the dimming overlay, ensuring your backup camera is 100% bright and visible. The overlay reappears once you shift out of reverse.

• Touch-Through Window Technology:
The overlay is fully non-interactive and "touch-through," meaning you can interact with all underlying apps (Google Maps, Waze, YouTube, Spotify) without any touch delays or blocking.

• Advanced Full-Screen Layouts:
Force the overlay to stretch across physical screen dimensions, ignoring system safe margins, covering camera notches, status bars, and navigation bars on compatible setups.

• Ultra Battery-Efficient:
Designed with automotive battery safety in mind. The GPS auto-dim mode queries coordinates only once when activated and uses lightweight timers to check the clock, ensuring zero background GPS or CPU drain while driving.

• 100% Private & Offline:
No account required. DashDim does not access the internet, send telemetries, or track your data. All sunset math and triggers are calculated locally on your device.
