Tired of Lock Screen widgets that show you your battery (which is already right there) or the weather (you just looked outside)? LSST is the app that dares to do what others didn't: let you display mildly useful text on your Lock Screen. Add a phone number, some information, whatever — in not one, but two distinct text slots (because we still can't just span the entire screen). Features: - Displays static text. - On your Lock Screen. - Nothing strange.
