Snap Swipe Drawer is an app to quickly access all your widgets from any app. Just swipe down from the top right corner of the screen (the same as you would to open the notification bar, but from the right). From this drawer for widgets, you can see and conveniently use any app you've previously added.
From Snap Swipe Drawer's main menu you can add as many widgets as you want. In fact, you can see a complete list of all the widgets for the apps you have installed at the time. All you have to do is select them to add them to the list and access them with just a tap.
Snap Swipe Drawer is a really interesting app that helps make using your widgets as convenient as possible. From any app, you just have to slide down from the upper right corner, and there are your widgets!
