Key Features
Three Steps to the Right Phrase
Genre (business, travel, daily life) → 21 categories → 510 phrases. Three taps take you to the situation you are actually in.
Formality at a Glance
Every phrase is marked as honorific or polite. Pick the register that fits the person and the moment.
When to Use It — and When Not To
Every phrase carries a usage note in your own language.
Readings and Pronunciation
Furigana and Hepburn romaji for Japanese; katakana and romaji for Korean, with liaison and nasalization rules applied. Every phrase has a play button, using the device's built-in voice — no extra download, no network.
Turn It Around and Show It
When words are not getting through, put the sentence full-screen and hand the phone over. Any phrase can also go out as a shareable card image.
One Search, Every Script
Find phrases by typing osewa — no need to read kana or Hangul. A single search sweeps the spellings and readings of all three languages, and exact matches come first.
Learn in Both Directions
Each phrase holds every language as an equal, not as a translation of one original. Swap "my language" and "the language I'm learning" and the same data teaches the other direction — the app's own interface follows (Korean, Japanese, English).
Two Ways to Review
Quick Review (5 questions) and the timed Speed Drop (10 questions) check what has stuck. Anything you miss links straight to its phrase from the results.
Your Library
Favorites, recently viewed phrases, and a per-phrase learning state (new, learning, mastered) — all kept on your device.
Phrases in the app, records on your device
The phrase data ships inside the app, so everything works on a plane or abroad without roaming. Favorites and learning history never leave your device.
