I just released version 3 of Off Remote.
The major new feature is that you can now send timed commands, so you can send a command telling your computer to turn off in 1 hour – or to go to sleep in 45 mins, or to log off, hibernate or restart.
I use it to turn off my media PC after playing video, and to set a timer on my computer when it is playing audio at night.
There are quite a few users who use it to check that their kids really have turned off their computers when they were supposed to!
You can get it at the app store now!
