BT Watcher software automatically locks your PC as soon as you leave its vicinity by assigning your mobile device. No need to worry about locking your PC anymore.

BT Watcher works by connecting with your Bluetooth-enabled mobile phone. Immediately after installation, you can assign your mobile device to BT Watcher. From that point forward, you won't have to worry about locking your screen manually. Instead, BT Watcher will do it every time you leave your computer's vicinity.
For added security, you can password-protect BT Watcher. Only those with the correct password will be able to deactivate the program. BT Watcher is designed to be unobtrusive in your work. It displays only a small icon in the system tray and balloons about important events.
You can define the timing for BT Watcher to show warning messages and separately the timing for BT Watcher to lock your screen. Additionally, you can define a custom command to execute. This command can be executed separately from locking your screen.
BT Watcher is best suited for business persons or professionals who travel frequently with their notebooks. The program can also shut down your computer or start other tasks defined by you. If you're looking for a way to keep your computer secure without having to remember to lock your screen every time you leave your desk, then BT Watcher is an excellent option.
