If you have super old Mac like 10.6.8 Snow Leopard use this version.
Iris mini is free and minimalistic version of Iris.
This is the entire Iris mini, no ui, no buttons, no many confusing options.
Iris mini has 3 modes which you can change by left clicking the icon (this blue icon above).
Automatic mode: During the day color temperature will be 6500K and 100% brightness and at night this will change to 3400K and 80% brightness.
Manual mode: Use 3400K and 80% brightness all the time.
Paused: Iris is paused and does not apply color changes.
What are this values?
The K values are color temperature. What this means is that the lower K means less blue light. Less blue light means you will get better sleep and less eye strain. How? Read the article about Color temperature.
The % values are brightness. This are luminance values, but innovative without PWM flicker. Basically this also helps your eyes hurt less. For more information check the Brightness article.
I want more values!
For most human beings the automatic presets and values are completely fine, but you know you and I are not normal, we want customization. Iris mini has option to get more values with its Pro version. You can get the Pro version for 2$. It’s one time payment like Iris for lifelong license including all new versions I make.
There are also hidden features in the Pro version if you need even more customization. For example there is a way to set Temperature to 200K or 9000K and brightness to 63% or as low as 20%.
I want Pro
You can buy Iris mini Pro from the Buy page.
