Eclipse works on most of the native iOS apps and even some third party apps. It darkens the UIViews to various shades of gray for easier night viewing. For third party apps that already feature a night mode, Eclipse does not affect those apps.
Eclipse can be configured via the Settings app. Options include the ability to enable or disable the tweak, darken wallpapers, and change the color of some OS text and highlighting from blue to orange.
While iPad support is not included in the initial release, Morán promises it will be coming soon. In addition, there are plans to make the tweak automatically change to night mode based on the time of day (think f.lux style automatic dimming). There will also be a scheduler so you can customize exactly when night mode turns on or off, and the ability to disable Eclipse in certain apps.
The tweak costs just $0.99 and should be available soon via the Cydia Store. It works on iOS 7 and ARM64 devices including the iPhone 5s.

Update: The tweak is now available for download! Go check it out!
