About this app

Potto is one account for learning Japanese and living in Japan: thirteen apps that share your level, your progress and your language, on iPhone, iPad, Mac, Android and the web, in 95 interface languages.

LEARN JAPANESE, N5 TO N1
20,873 learnables cover vocabulary, grammar and kanji across every JLPT level. Each entry carries readings, senses, pitch accent, etymology and keigo registers, cross-checked against reference dictionaries with citations. Kanji show radicals, stroke counts and the readings that actually appear in words. 1,376 lessons and 97 journeys turn those entries into a path: take the placement test, get a level, and follow the next lesson the app puts in front of you. Flashcards, questions and 564 counters fill the gaps a textbook skips, like which word to use at the register.

PLAY YOUR WAY TO FLUENCY
Shiritori against the app in Japanese or English, with a fifteen-second clock and every word you play scored. Crosswords, quizzes and a counter game that runs with no account at all.

COOK FROM THE SOURCE
Recipes painted in mineral pigment on washi, each with the numbers a cook needs: servings, prep and cook time, difficulty, metric, US and Japanese measures. Cooking mode reads one step at a time with timers running and voice control for messy hands. A growing calendar shows what to sow and harvest in your climate zone this month, and a shopping list and pantry follow your recipes.

PLAY THE MUSIC
Sheet music engraved in the app with the kana under every note, playback, score and part views.

UNDERSTAND THE COUNTRY
6,945 history entities, from eras and people to the dishes and words that came with them, linked back to the learnables they explain. Places, geography and the stories behind them.

GET REAL HELP
The Legal app explains Japan's five legal licences and what each may do for you, so you know who to ask. Counselors and interpreters are a message away for the moments a dictionary cannot handle, from city hall paperwork to a doctor's visit. Examinations give you JLPT-style practice and school entrance preparation.

MADE FOR LIFE IN JAPAN
Every screen is available in 95 languages, downloaded once and kept on your device. Switch accounts for family members. Your progress, level and language follow you across devices.

Potto is built in Etajima, Hiroshima, by people who live here. Start free, take the placement test, and keep whichever apps you use.
