Night Time Mode
Night time mode that will be suitable for low-light environments. The app will know the time zone the user is in and will adjust when it starts getting dark outside. This feature should be implemented in the Mac App and also the future IOS App as well!

No need for some app-specific solution to this..
Why not just use F.lux system wide on MacOSX? (iOS 9.3 will have a similar system feature)
