Last time this app was free was in May 2019.
Yomiwa is a dictionary, translator and optical recognizer designed to help you read, write and learn Japanese.
Yomiwa's powerful offline Optical Character Recognition (OCR) engine can recognize more than 4000 Japanese characters in your pictures or with your device camera. Yomiwa will help you read newspapers, books, menus, signs or your favorite mangas.
Yomiwa's dictionary is extensive, intuitive, fast, and delivers Japanese word details into more than 20 target languages. You can input words in any language, alphabet, or even by drawing.
It's also on android but it's always been free. The best japanese dictionary I've used.
