ダークモード非対応・文字サイズ変更不可 This app does not support accessibility. For example, even if you set the font size large in the accessibility of the settings app, it has no effect on the characters displayed in this app. I've known this app since around 2010 when I was using an iPhone 4. Since then, iOS has also been updated several times. Similarly, I expected that this app would be updated to support accessibility someday, but there is still no improvement in it.
