Switching Apps on Android is generally accomplished using Android’s native card-style multitasking solution. We’ve seen some apps that provide quick access to favorite programs with a swipe from the side of the screen with the original Sidebar, Sidebar plus, and Appsi Sidebar.
However, when you are in a program and want to switch to another running, you always had to go to the multitasking button. Depending on your device, that might be pressing and holding the home button for 2 seconds, double tapping home, or pressing the dedicated softkey. Switchr by XDA Senior Member Mohammad_Adib makes going back to a previous app as simple as swiping your finger. Mohammad_Adib, the same developer who gave us Sidebar and Floating Stickies, brings us a new way to switch between running apps that makes you wonder why this isn’t standard in the OS.
Switchr is a well designed and well polished app with a simple, yet practical function that allows users to access their running apps quickly and conveniently. The app is backed by an active and committed developer. It works with Android versions 4.0 and newer, but the dev intends on bringing support to Gingerbread devices as well. The beta will end on October 20, and will be followed by official release.
