From the developer:
Lock It Up is a cloud based tool for locking your computer. That means it works anywhere. You don't have to be on the same wifi network or even be on the same continent, since it all works through the cloud. The app runs in the background of your computer and uses barely any RAM or CPU.
You may want to check out more software for Mac, such as Ettercap, SecuriSSH or Tattletale, which might be similar to LockItUp.
