To control those fonts or use your iPad as a creative workstation, you work directly through the app you’re using them with. You can install custom fonts and apply them to compatible apps on your Apple mobile devices. You still can’t change Apple’s system fonts, but updated font features significantly advance mobile workflows.
This feature lets you install custom fonts in TrueType Font (TTF), OpenType Font (OTF), or TrueType Collection (TTC) formats, making it easier for creators to put a unique display and text face on their leaflets, posters, and reports. Designers, teachers, artists, presenters, and creatives rejoiced when recent versions of iOS and iPadOS facilitated the use of custom fonts on Apple’s mobile devices.
