With Themer, installing and changing your Android themes becomes a one-click no worry solution. While still in the early stages, you can now sign up for the upcoming closed beta test that will be happening soon.
Putting their backing into Themer is MyColorScreen.com, a large community of designers that offer different theme selections that come complete with widgets, backgrounds, and icons. Because installing a theme in practice can be a pretty cumbersome ordeal, not everyone has been utilizing this option of Android as much as they could be.
Beforehand, you could follow some YouTube instruction videos put on by the people responsible for MyColorScreen.com that would lead you on a step-by-step process of how to get a theme installed on your device. Now, with Themer, it is a much easier and seamless process that is almost dummy proof.
Themer will be available for free when it is ready for the general public. As for right now, you can register to be a closed beta participant on their site.
