I suddenly found out that the iOS and Android app of Twitter now has a night mode, which when enabled will change the color theme of the twitter account to dark. I personally like the night mode, since its easy to the eyes and you can easily focus on tweets with photos or video.

You can turn on the Twitter Night Mode by going to the SETTINGS section of the App then tap “Turn On night mode”, if you do not see the option on your phone, you will need to upgrade your twitter app. You can download the free update from the App Store and Google Play.
Here are some screenshot of the Twitter night mode.
The Twitter Night mode was introduced last August.
