Smart Lock Lite gives you access to one app at a time without unlocking your phone.
Great for changing songs while running or driving. It runs in the background and works with every app.
Smart Lock Lite uses the built in lock screens so you know its secure.
Smart Lock Lite requires internet permissions to display ads. If you don't trust me, or you won't want ads, then buy the full version of Smart Lock.
Full version adds parental controls, more lock types, widget, no internet permission.
Does not work on the Xoom yet.
