Fontismo, my iOS-based utility which provides completely free and account-less access to 50 great open licence typefaces, now works on iPhones as well as iPads. It’s also fully compatible with iOS 14 and features improved font previewing, including pinch-to-zoom scaling.

You can download Fontismo 1.1.0 from the App Store and read all about how to use it here.
You can learn why I wrote Fontismo by checking out this blog post. In a nutshell, I wanted the same open licence fonts on my iPad as I used on my Mac, and I wanted them without having to create an Adobe account or use some other third-party app that really just wanted to sell me things.
