I have an iPhone 6, and I wanted to download Zedge. I can't find it in the AppStore and when I went to the Zedge site directly, I couldn't download to my iPhone. Am I doing something wrong or is Zedge no longer available for iOS?

I'm on iOS 9.02 on an iPhone 5s, using a Windows 10 computer. Latest version of iTunes. I have the Zedge app installed on my phone and the Zedge Tonesync on the computer. In the past I've been able to download and sync ringtones from Zedge to iTunes with no problem, although it's been a while...
