Lots of fonts, but many live behind a 1-time $2 in-app purchase (that’s $2 total, not per font!). I think the cost is quite worth it. I’m quite happy with the ease of use. It’s too bad the app can’t also remove installed fonts (that you must do manually from settings) but that’s a minor shortcoming.
