Installing fonts on iPadOS
Fontcase is a free iOS app that lets you install custom fonts on iOS and iPadOS. You can quickly import fonts from your iCloud Drive or Dropbox and they'll be available in other apps, including Figurative.
Fontcase is completely open source, so your privacy is insured. The app only adds fonts to your settings and does not modify them at all in the process. For more information on why this is important, see the app's Help tab.
