全半チェンジ - 全角半角ひらがなカタカナ変換アプリ

It is an application that performs the conversion of a string of double-byte / byte / hiragana / katakana.

I tried to create because when I had double-byte string phone number, could not be registered as it is.
You can also specify the text before conversion in the share from the other application.

Please try to convert again replace the text before and after conversion text in the "↕" button when the inflexible way to convert.
