Android: Jumping between apps in Android usually requires you to either go back to your home screen or swipe sideways between open apps. Swapps! is a new utility that lets you pull up a list of open and recently used apps on the side of the screen at any time.
Swapps! reminds us of previously mentioned HomeFlip, in that it makes it quick to jump from app to app without going back to the home screen. Just swipe from the left side of the screen to the centre to bring up the Swapps! menu, which is packed with "starred apps" or apps you've listed as favourites, apps you've used recently and your complete app list.
The developer specifically built the app so it could run in the background without seriously draining your battery, and you can toggle the notification bar icon so it's transparent. The app is free, and a $2.50 in-app purchase removes the ads. Hit the link below to give it a try.
