Hi @John Hennebry3, thank you for reaching out!
Match is a Web App. It is not something that you can download. A Web App is software that runs completely in your web browser (Chrome, Firefox, Safari) that can optionally be installed as a fullscreen app on iOS (iPad, iPhone)
When you are signed in with your color.io account3 you will automatically benefit from all the Match Pro Features you purchased.
Let me know if you have any questions!
