ComputerTime is available for the Windows platform only.
We wish we had all the time and experience to create versions of ComputerTime for all of the platforms that are available today, but we don’t have all the knowledge and we keep busy enough with the work that’s on our plates.
Some of these other platforms may have built in parental controls, and they might not be as flexible and full of options the way that ComputerTime is, but they may be effective for basic control.
I noticed that the Kindle Fire has a way to set limits on what kinds of apps can be used and for how long. I’ve heard that the OS X (Macs) have basic time limits.
So, basically, no, ComputerTime only works on Windows and we have no plans to go to any other platforms in the foreseeable future.
