Please note you will not be able to use the software until you are given a user name and password.

Before you can use the software, you must take a few measurements on your computer monitor, which requires a metric measuring tape.  A paper version, which you must print, cut-out, and taped together can be downloaded here.

Apple Rainbow   MacOS

  • This is built on macOS Sierra. It’s not guaranteed to run on anything older. If you’re unable to update, you would need to use a Windows or Linux machine if you have one available.
  • Click on this link to download the zip file.
  • Open the zip file. The app should extract itself. You can then drag the app to your desktop or applications folder if you like.
  • Right click or Ctrl + click on the app, and select “open.”  If you left click, it may not allow you to run it for the first time.
  • You will see a message that says “Tritheia is from an unidentified developer.  Are you sure you want to open it?,” don’t worry, it’s safe to proceed.  Go here to learn more about this.

Linux  Linux

  • Click here to download a 64 bit binary.
  • Unzip the file in whatever directory you want.  This will create a new folder called “Tritheia 64 Linux.”
  • Enter the folder and run the executable file named “Tritheia.”
  • Tritheia is developed on GNU Linux.  If you need a 32 bit binary or it doesn’t work with your distro, please let me know.


Will it run on Android or iOS?

  • The short answer is “no.”  It may run on Android devices with larger screens in the future, but there are no immediate plans to port it at this time.  It will likely never run on iOS due to Apple’s strict app store rules.
