I bought this application under the impression that its an add-on keyboard like Emoji.
However this app requires you to type your entry on its "clipboard" and copy/paste it to whichever application you are using, which is extremely inconvenient.
In addition, I cannot find the Zhuyin input method, resulting in my one-star review.
If these problems were resolved I would definitely give a 5 star review since the keyboard really seems easy to use.
