What is Umwelt?

Umwelt locks your computer when you are away from it and unlocks when you come back, automatically or tapping the fingerprint reader. By measuring the strength of the Bluetooth signal from your phone, it "senses" when you are close or away.

See more details in the tutorial: How to install and use Umwelt on Windows.
