These programs filter the blue light which keeps you awake when using your phone display at night. Is there any alternative to these programs for windows phone available?
Still nothing on this?
stuff like this should already be in the system.
There's plenty of things that need to be done.
Heck, iOS has only just added this feature and Android has not had an official implementation.
(Sure, there are some apps that do a crude overlay and CM has a nice version of it...)
