App to manage screen brightness on Android. Eye strain can be a huge problem for anyone who spends a lot of time looking at screens, whether it's a desktop monitor, a TV, or even a smartphone.
Research has shown that exposure to blue light (the kind emitted by electronic screens) at night can disrupt the circadian rhythm, and the biological processes involved in sleep cycles. Wouldn't it be great if there was an Android brightness app that reduced or even eliminated this problem?
That's why you should start using one of the following Android screen brightness apps. You will be surprised at how useful they can be.

If there's one thing that puts CF.Lumen ahead of all other brightness apps and that adjusts colors by directly manipulating gamma values rather than using a colored transparent overlay (although an overlay option is available in the settings).
All automatic brightness adjustments are made based on your location and time of day. You can customize the adjustment and you can activate some options like “Force sleep mode in the dark” or “Force day mode in bright ambient light”. Useful when, for example, you are in a bright room at midnight.
And here's something very interesting from the developer: the Pro version of CF.Lumen adds new features such as quick activation buttons, notification options and removal of the few updates, but if you wish, you can simply activate the "Freeload" setting to get all Pro features without paying. Buy it if you can, but if you're short on cash, it's nice to know this option is there.

Lux is one of the best Android brightness apps available. It's simple and minimal, and walks you through setup with the Lux Wizard, meaning you won't be overwhelmed with confusing settings. It offers four different methods for automatic backlight adjustment:
- Ascending (adjusts how the ambient lighting changes)
- Dynamic (adjusts only with significant changes in ambient lighting)
- Periodic (adjusts according to a predetermined schedule)
- On Wake (adjusts when device wakes from sleep)
But if you want more granularity, you can dive into Lux's settings and manually adjust almost anything you want, including minimum and maximum brightness levels, when brightness changes, etc.
One thing I love about Lux is that it can set the brightness below zero. Sometimes Android's lowest brightness setting is still too bright, especially when you're in a dark room. It also comes with a widget that you can use for quick changes to the brightness controls.
There is also an optional Pro version with extra features: using the camera to read ambient light, advanced user advanced settings for precision control, astronomer mode for stargazers, automatic night mode for color temperature control based on time (i.e. reduction of blue light at night) and more.

Twilight is an app that does something similar to F.lux, the well-known blue light filtering app for PC: using sunrise and sunset times as indicators, Twilight automatically adjusts the screen (how much blue light is emitted) so to reduce the disruption of your circadian rhythms. After dark, Twilight dampens the screen temperature using the blue light filter and heat intensity.
Don't you care about the blue light? All right. Twilight also has a dimming factor, so you can override all temperature and heat controls and automatically adjust the screen brightness to match the same sunrise and sunset settings.
There is an optional Pro version with additional settings: custom sunrise time, custom sunset time, custom transition time (the time it takes to fade from non-dampening to full damping when touching sunrise or sunset times) and other.

Velis replaces Android's default auto brightness feature. It comes with an installation wizard that allows you to go ahead with the installation.
Velis gives you a graph (ambient light reading along the X axis, screen brightness along the Y axis) and lets you have full control over how the auto brightness graph should look at each point. At such an ambient lighting, it is possible to set the brightness for A; in ambient light so-and-so, B. Velis brightness fills in the gaps.
Other great features you'll find in Velis: superdimming (even darker than Android's default minimum brightness), excluded apps (Velis won't run when these apps are in focus), and multiple profiles for different auto brightness charts.
