Twilight Screen Filter App Review

Twilight is a screen tinting and contrast control app for Android that is designed to reduce the level of blue light emitted by your device to cut down on sleep issues. Blue light exposure in the evening has been linked with sleep disruption as well as linked to migraine as a trigger.  By default it looks at your local sunrise and sunset times and filters out more and more blue later in the evening, but it can also be set to a static level of filtering throughout the day.

It’s a free app with no restrictions that works well at no cost. If you find it very useful, there is the option to upgrade to pro for a few pounds, which ensures that the developers get paid for their hard work and adds extra features.

Twilight does exactly what it claims to do. It filters out blue spectrum light and softens the screen automatically as daylight fades. I have found it very helpful for general use, but as it changes colour, it doesn’t work well for video or games. It is excellent for anyone who regularly reads on their phone/tablet in the evenings, whether it’s a novel, browing the internet or social media. I find it useful during a migraine as I seem to be a lot more sensitive to blue light.

It is generally recommended not to use backlit devices for a couple of hours before going to sleep, but if you do, we definitely recommend using a blue light filtering app. Twilight has been my go-to app for the last 2 years and I have been very satisfied with its minimal effort performance.


The review is based on the Twilight App using a variety of Android phones, including Nexus, HTC and Samsung. Read more about Ergohacks’ ecoaccess and feature icons used in reviews. This article was first published on 18 September 2014 and last updated on 15 June 2016.
