Huh? Did I lock the door? So that you don't have to worry about "what's going on", this app starts the app when you lock the door and records it. The time is recorded, so you can check when you turned it on or not. It also resets automatically at the specified time, and you can turn everything off so you don't have to turn it off. Other than at home, I think that it can be used for offices and stores, etc., to check the lockdown. [Basic Features] Location registration (name, photo, with or without automatic reset, with or without logging) Reordering Places Once registered, it's designed to be simple enough to use every day with a tap when you lock the door.
