Followed directions on download, pushed the install button, nothing happened. Checked my fonts folders, but the fonts not there either. Sent message to developer couple days ago asking for help, but developer never responded. However, this gave me the idea to search "Harry Potter fonts" online which brought up a Harry Potter fan club which has these fonts and many other Harry Potter inspired fonts (29 in total) for free download. Clicking for the developer website said this app is for iPhone not Mac, and the iPhone version did work on my iPhone. Since I would never have thought to look for and then found all those fonts online at the fan club is why I gave 3 stars instead of 1.
