Aplicación en catalán. Aquesta aplicació permet estudiar Kanji seguint el pla d'estudis de l'Escola Oficial d'Idiomes de Barcelona Drassanes. Es poden seguir 3 mètodes diferents per estudiar: - Kanji: Veus el Kanji i has de pensar el seu significat i pronuncia. A continuació veuràs el vocabulari relacionat i hauràs de pensar els significats. - Vocabulari: Apareix la paraula i has de pensar la pronunciar i el significat. - Yomi: Es mostra el significat i pronuncia d'un Kanji. Has de dibuixar-lo i després podràs comparar-lo i veure com es dibuixa. Finalment es repassa vocabulari. Funcionalitats: - Cada mètode permet seleccionar quina o quines lliçons es volen estudiar. - Es pot marcar un kanji o una paraula i després estudiar només les marcades. - L'ordre de repàs pot ser consecutiu o aleatori - Si no tens temps d'acabar de repassar una lliçó, no et preocupis, l'app recorda per on anaves i després podràs continuar.

Kanji Adventure walks you from N5 to N1, at your own pace. A COMPLETE, FREE DICTIONARY Thousands of kanji sorted by JLPT level. Pick the ones you want to work on, and for each one find its readings, its meanings and an example word with its translation. LEARN, REVIEW, REMEMBER Learn mode earns you points kanji by kanji. Quick Revision slides through a whole level with no scoring, just practice. Then SRS brings back what you already know at growing intervals, so it does not fade away. 190 KANJI TESTS The 試 button opens exam mode: ten questions taken from the kanji part of a JLPT-style test, entirely in Japanese. No feedback while you work — your answers are marked at the end, with the correct answer for each question. The first test of every level is free. THE RIVER 278 steps to sail up across Japan, boss fights along the way, and 200 real places to discover: temples, festivals, gardens, hot springs. Each step you clear reveals an illustration and a real location you can open in Maps. OTTERS TO COLLECT They show up when you work well. SIX LANGUAGES English, French, Spanish, Vietnamese, Thai and Indonesian. FREE AND PREMIUM The dictionary, the river, the boss fights and SRS review are never limited. Learn mode and Quick Revision share a quota that refills every 5 hours; when one runs out you can watch a short video to get half of it back straight away. Premium removes both limits and opens all 190 tests: 1 month, 3 months or 1 year, each with a free week, or lifetime access as a one-time payment.
