Get freedom from your phone’s obvious limitations. Use CF.lumen, made by Chainfire, a Tools app on your PC or Mac with BlueStacks, and level up your experience.
About the App
Ever feel like your screen is just a bit too harsh on your eyes at night? CF.lumen, crafted by Chainfire, gives you control over your device’s display colors in a really clever way. It changes your screen’s tint based on the setting sun—or whatever schedule you prefer—so whether you’re up late reading or just want eye comfort through the day, things feel a lot easier on your vision. It’s straightforward, but the amount of fine-tuning is impressive. You can even use CF.lumen on your PC with BlueStacks for that same comfy experience on a bigger screen.
App Features
-
Automatic Color Adjustments
Let CF.lumen automatically tweak your screen’s colors depending on the time of day—think warmer hues when evening hits, or set your own custom times to match your routine. -
Sleep-Friendly Filters
There’s a special red filter that pops on by default during your sleep hours. That’s the color that does the least to mess with your eyes—and it helps keep night vision sharp if you need to get up in the dark. -
Sensor-Based Adaptation
Got a light sensor? CF.lumen can use it to figure out if you’re in bright sunlight or complete darkness, and then pick the right display filter automatically. Calibration settings help if your sensor’s a little unpredictable. -
Color and Grayscale Filters
You’re not locked to one look—play with options like grayscale, invert colors, or adjust temperature to make things cozy. Fancy a pure red or blue effect? Those modes switch your display to nuanced versions, not just flat colors. -
Support for Colorblind Users
Tweak the app’s filters for different types of colorblindness, with enhancements named for protanopia, deuteranopia, and tritanopia. Useful if you want to see finer color details. -
Pro Features for Power Users
Go Pro to get rid of reminders, unlock auto-start, use advanced notification controls, and hook up to Tasker for automations. Handy if you want more control and fewer pop-ups. -
Low Performance Impact
Worried about lag? Filters generally run smooth, and you can even turn on a special performance mode if things ever feel sluggish on your device. -
Customizable Notifications
Quick control from the notification shade: it’s easy to disable filters or switch to sleep mode with just a tap (Pro mode adds even more flexibility). -
Respectful Privacy
The permissions are mostly there for useful extras like using your location for sun tracking. No sneaky data-sharing with anyone except the built-in Google services.
CF.lumen grows with Android, but keep in mind that, as the system changes, a future update might require tweaks. For now, though, it’s all about giving your eyes—day or night—a break.
Big screen. Bigger performance. Use BlueStacks on your PC or Mac to run your favorite apps.
