文字入れくん is a free multimedia app available on iPhone that allows users to add vertical or horizontal captions to their photos. With this app, users can easily add captions to their images and customize the font style from a wide range of options.

One of the key features of this app is the ability to add ruby text. For Kanji characters, users can simply add "《furigana》" after the Kanji to add ruby text. For non-Kanji characters, users can use the "|" symbol to indicate the starting point of the ruby text, followed by the desired text.

文字入れくん offers a variety of fonts to choose from, including popular options like ヒラギノ明朝, ヒラギノ角ゴ, ヒラギノ丸ゴ, and 游ゴシック体. Additionally, the app includes fonts from Typing Art and Google Font, all licensed accordingly.

Please note that this app is specifically designed for adding captions to photos and is not suitable for creating LINE stamps.
