You must have this app
If your an east asian, the iOS devices have only one font for your mother tongue. Just one, not two! Thus if you make a Pages document, it would be a monotonous work. Apple says it considers various fonts are the crucial part of its identity, but not for us, the east asians.
Anyfont is a solution. You can implement almost every font on your iphone and iPad. This app makes your devices more valuable.
Of course it isnt perfect. If you have large font files which is covering numerous languages cant be added. Your font file must be smaller then 10MB or less.
Overall,Im very satisfied with this app.
