I need an app that will entirely disable the phone while it's in motion. It doesn't matter about being a passenger or not; if the phone's in motion at driving speeds I want it to be disabled. Do Not Disturb While Driving is not good enough because it can be overridden by the push of a button. I want the phone to not function at all until the vehicle is stopped.
Added (1). This is not an issue of myself not using my phone; I want to disable my son's phone while he's driving.
