Alternatum is a powerful applicaation Switcher in your Reachability View! It shows your available RAM, can close all apps and has some Settings Toggles, thanks to Flipswitch (more are coming soon)! It also has the same functionality as the Stock iOS Switcher, you can tap an app to switch to it and swipe it up to close it! It also has an Activator listener, so that you can invoke this Switcher in any way you like! This also means that it is compatible with devices that don't normally have a Reachability view, so this tweak works perfectly on all iPhone and iPad models!
