For the universal iOS application, each glyph has a file, starting with
icon-ios-, for the same color options as the Mac (though, regardless, it'll be paired with teal text, so that color tends to work best). There are also Retina display
To use these icons I recommend duplicating your perspectives, so you have one you use on the Mac, and one you use on iOS, each with the appropriate icon file.
Note that installing these icons requires OmniFocus 2 for Mac with the Professional upgrade. Using custom perspectives on iOS also requires the Professional upgrade.
- In the Menu, go to Perspectives > Show Perspectives
- Click on the Perspective you want to edit the icon for. (Note that Inbox, Projects, Contexts, Forecast, Flagged, and Review all cannot be changed).
- Select the icon you want to use. The
distfolder has all the usable icons. There’s a folder for each one which contains files for each of the 8 colors for the Mac version, each of the 8 colors for the iOS version, and the
@2xvariations. You should only use the
@2xversions if you have a Retina Display Mac or a Retina iOS device.
- Drag the icon you want to the icon well in the Perspectives window, or click the down arrow on the icon, and then Choose File, and navigate to the icon.
