Level Lock is a smart lock that lets you control your door with your iPhone, Apple Watch, or voice. It is designed to be invisible, fitting inside your existing deadbolt and keeping your exterior hardware unchanged. Level Lock works with Apple HomeKit, which means you can use the Home app or Siri to lock and unlock your door, create automation, and share access with others. You can also use the Level app to manage your lock settings, view activity history, and use key cards or regular keys as backup options.
