CleverPin cydia tweak allows you to make your iPhone ask for passcode intelligently: you can choose to automatically disable it while you’re connected to your home network (more than one network supported, add the network you’re connected to with only 1 tap), listening music or charging battery. You will never need to waste time again to disable the passcode (even decreasing your own protection), because you’re iPhone will ask you for it only when it’s actually needed. You can also choose to automatically re-activate the passcode after a certain time of inactivity.
No new icons will be added to your homescreen. Configure CleverPin options from your Settings.app
