Another handy feature of iOS 7 is Automatic Updates for your apps. No longer do you have to launch the App Store app and check for updates manually. If you enable this feature, updates are pushed automatically to your device and installed behind the scenes.
Why you should turn this feature on:
You like to keep things up to date but hate constantly checking the App Store for updates.
Why you should turn this feature off:
If you prefer to control everything that is installed on your device, turn this off. If you don’t have frequent access to WiFi or have a small data plan, you won’t want your data getting eaten up by app updates. If that’s the case, then simply turn off “Cellular Data” so the App Store will only push updates when a WiFi connection is detected. Finally, sometimes developers push out updates that have bugs so you may want to keep using the current working version until it’s fixed.
