Themer, one of the most innovative launchers for Android devices recently, has been available in a closed invite-only beta since the past few weeks. That changes from today though, as the launcher has entered into an open beta.  This means that interested users can get the Themer code by simply entering their email ID on the website of the app. For the unknown, Themer allows users to apply absolutely stunning themes on their Android device in a matter of a few seconds. The themes have all been very well done, and can completely transform the look of your device. The current list of themes, while not very vast, includes everything from a GTA V to Breaking Bad inspired theme. I took Themer for a spin earlier this month, and found it pretty impressive. However, the launcher is strictly meant for novice Android users who just want the look of their device in a matter of few seconds. Power users will find the launcher lacking quite a few must have features like gestures and icon pack support.
