Kotobaya ことばや
An offline-first Japanese dictionary and vocabulary trainer for iPhone and Android.
Kotobaya brings lookup, kanji composition, and review into one place. It is built to work on a train with no signal, and to keep working when you stop paying attention to it.
- Dictionary search with kanji composition analysis
- Spaced-repetition review that adapts to what you forget
- A reader for your own texts, with every word linked
- Fully offline, and no account to create
