So far so good – Sprezz - Custom Keyboard Themes and Fonts Review
I've downloaded a couple font apps, and typically they're confusing or they lack pretty basic features.
This app is pretty simple, and I have yet to encounter an issue when using it. However, I haven't used this app for more than 5 minutes, so I don't know if I can give it above 3 stars just yet (the app offers you locked fonts in exchange for a review, not too long after you first open it).
