KillBackground10 lets you force quit all apps from the App Switcher
Many people leave their apps alone in the App Switcher until they start to have problems with them, and will use it to force quit those apps so they can be restarted again. Even though iOS handles its very limited allocation of memory automatically, it's not always as efficient at it as you'd like it to be. This can impact your device's animations and performance, and it's why iOS developer ichitaso released KillBackground10, a jailbreak tweak you can use to force quit all apps on iOS at once.
