The Fonts tab has a row per kind of text, such as normal text and headings. Each row shows its font, or Default.

Changing a Font

1. Open Design, then Fonts

   In the Unbound section of Discord's settings.

2. Tap a row, then a font

   Your own files list first. Search to narrow the list.

3. Relaunch Discord

   Close it from the app switcher, then open it.

To undo, tap the row, then Reset, and relaunch. A font Discord can't find falls back to Discord's.

Adding Font Files

Copy the file straight into Unbound's Fonts folder, not a subfolder, then relaunch Discord. Every row then lists it. To remove one, delete it and relaunch.
