SONAGI - Customizable Wordbook is a free Android application developed by sonagigureum under the Education & Reference category. This app is a customizable wordbook that allows users to add, edit, and delete individual vocabularies within the app. You may upload your wordbook created by various programs, including Microsoft Excel or Google Spreadsheets. The app allows you to classify vocabularies into four categories, which allows repeated learning in an effective manner. Suitable for learning all foreign languages, you can listen to the pronunciation of words in all languages of the world supported by Google TTS.

The app remembers where you left off, so there is no need to waste time in finding the word you last left off. You may remotely turn to the next word using the Bluetooth shutter. The app also allows syncing between the list view and the expanded view. The invisible functions make the app more user-friendly, including moving to the first/last item in the list, creating add, modify, and delete buttons, editing vocabularies in the expanded view, and more. However, if you did not purchase it, you will have a limited 30-day free trial playback, and the ads are included.
