辞書アプリ コトバンク is an educational and reference application available on Android. Developed by DIGITALIO, this free app allows users to easily search through multiple dictionaries simultaneously. However, it is important to note that currently, only the Progressive English-Japanese and Progressive Japanese-English dictionaries are available for use within the app.

In addition to providing text-based explanations, 辞書アプリ コトバンク also offers explanations through photos and illustrations. Users can manage their search history and save their favorite terms for future reference. The app also features a "Keyword of the Day" section, where users can easily look up frequently mentioned words or commonly confused terms.

Please note that there may be display issues on Android 4.4 devices. If this occurs, simply close and reopen the app to resolve the problem.
