Iris Mini is the minimalistic version of Iris. It doesn’t have a user interface, just a taskbar icon on which you can right-click and see the menu.
In the free version, you’ll see the three preset modes – Automatic, Manual and Paused (read more about them in the Modes and Types section).
In the Pro version, you can see additional settings for brightness and color temperature.
