Support the app
Presets for Chase Bliss is free, unofficial, and built in our own time. It has no ads and no subscription, and it never will. What it does have is a bill for hosting, for the developer accounts at Apple and Google, and for the evenings that go into every release.
If the app has earned a spot on your phone, a donation through Ko-fi keeps it going. Any amount helps, and none of it is expected.
