Gister is set in three open typefaces, all released under the SIL Open Font License 1.1. The licence lets us bundle and use them freely; it does not let anyone sell the fonts on their own.
- Syne — by Bonjour Monde. Copyright 2017 The Syne Project Authors. Display and headlines.
- Karla — by Jonny Pinhorn. Copyright 2012 The Karla Project Authors. Body text.
- DM Mono — by Colophon Foundry for Google. Copyright 2020 The DM Mono Project Authors. Counters and captions.
The full licence text for each face ships inside the app bundle (OFL-Syne.txt, OFL-Karla.txt, OFL-DMMono.txt).
