Adobe Comp CC is a lightweight composition app for iPad. It lets you quickly wireframe ideas for print, web, and mobile.
Fonts synced from Typekit are available in Adobe Comp CC, the same as in the Creative Cloud desktop application. All the fonts you’ve selected on your Typekit account will be listed in the Comp CC font menu under “Typekit." Tap the download icon to use them in Adobe Comp CC as well.
You can browse and sync fonts right within the app. Any fonts synced within Adobe Comp CC will also be synced to the Creative Cloud app and available on your desktop.
