I never (NEVER) review apps and least a ringtone app (because I dont have much use for it). But this app allowed me within minutes to recover an old recording of my kids that used to be my ringtone in an ancient clamshell phone, and make it a ringtone in my iPhone. Wow! So simple.
It looks spooky with all the Chinese writing, but its simply genius.
