Works perfectly. Just installed a dozen fonts from DropBox onto my iPad Pro running iOS 9. The installation process is complicated involving many steps in two different programs. First you have to put the font onto Dropbox (or email it to yourself, or add it to the application via iTunes). if you’re using Dropbox, you have to pick the file, then tell dropbox to “send link,” which gets you into a dialog that lets you pick AnyFont. As I said, complicated. If you’re using iTunes, the process is simpler. Once you’re in anyFont, you just click on the font name and it walks you through the installation process. There’s no sort of batch load, so you need to import the fonts one at a time, but how often do you do this? Anyway, the imported fonts are now happily working inside Keynote. I’m happy.
