Just browse through the library and you will see numerous fonts with their respective font names in order to reference within your apps or designs.
I came across this idea while I myself was working on a few applications and saw the need for a Font library for reference.
You can even write a few lines of text to see how it will look in different fonts immediately.
Since all of the free versions I saw contained adds, I decided to make one completely free with no strings attached.
