About this app

Umeboshi makes learning new vocabulary faster and easier. Using the power of AI, Umeboshi can quickly turn words and text into fully formatted flashcards across a variety of languages.

Once your flashcards are created, Umeboshi’s built-in spaced repetition system helps you review vocabulary at the right time, reinforcing what you’re learning and helping you retain new words for the long term.

Spend less time making flashcards and more time learning.

Data safety

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.

What’s new

Added spaced repetition review system to the app itself. Cards can now be added to a deck and be reviewed in the umeboshi app itself without requiring AnkiDroid app to interface with. Anki functionality is still present and can be toggled on in settings.

Also added support for other languages besides Japanese. Settings are saved on a per language basis allowing different review structures for different languages.
