I am using this application since I started using smartphones and it works like a charm. This is by far the simplest and most effective app to reduce the screen brightness so that you can check Facebook notification, read news and watch your favourite series when the lights are off.
The free to use app will only take 304Kb space on your Android handset and applies a shade that acts as a dimmer to ensure your eyes don’t hurt. Just tap the screen widget and the screen brightness gets reduced by the pre-set level that you can customise as per your comfort.
Verdict: The most effective and simple to use app to reduce the display brightness.
The app features five filters: Natural, Yellow, Brown, Purple and Light Dark, which can filter 0-80% of blue light emitting from the Android devices.
Verdict: Blue light Filter features a good number of filters to change the display colour tone to offer a comfortable viewing experience.
The overlay filter acts as a dimmer to darken the screen that helps to avoid headache and eye strain at night. The app comes with auto-enable & disable feature and one-click widget to activate.
Verdict: A nifty app with one-tap widget to reduce the brightness level.
Its algorithm filters the flux of blue light after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity can be adjusted to the sun cycle so you don’t need to manually activate the app.
The app even has a preview button to check how the display colours will look upon activating the filter.
Verdict: The application features a preview feature and automatic controls to change the screen’s colour tone.
Besides, the app comes with a launcher widget with on/off button, profile select button and a brightness graph.
Verdict: The app offers a slew of features and works as a replacement for system provided auto-brightness control.
