NinjaLock, developed by Linough Inc., is a lifestyle application designed for use with the NinjaLock smart lock device. With this app, users can conveniently operate and adjust the settings of their NinjaLock.

One of the key features of NinjaLock is the ability to use your smartphone as a key. By attaching the NinjaLock device to the inside of your door, your smartphone can replace the traditional key. This eliminates the need to carry around physical keys and provides a more convenient and secure way to access your home.

Another useful feature of NinjaLock is the ability to invite friends to have opening rights to your lock. By entering their telephone numbers in the app, you can transfer opening rights to them for specific time slots. This is perfect for allowing friends or family members access to your home when you're not available.

Additionally, NinjaLock offers various convenient features such as an auto-lock function that automatically locks the door after a specific time period. The app also keeps a history of the opening and closing of the lock, providing users with a useful record.

NinjaLock is available for free and requires a NinjaLock smart lock device by Linough Inc. to use. Please note that the app requires Internet access and devices must be equipped with Bluetooth 4.0 or higher. It's important to ensure a solid signal for proper functionality, and be aware that continued use of GPS running in the background may decrease battery life.
