Great resource for learning Japanese.

Спасибо вам за ваши труды

Это прекрасно исполненный русско-японский словарь. Использую его каждый день, пользоваться им одно удовольствие. Видно, что вдохновлён красным англо-японским словарём “Japanese”, но при этом ориентируется на Ру-сегмент.
Из замечаний, могу выделить только то, что при поиске некоторых слов, в маленькой карточке слова показывается только доп. информация, но не перевод. Но это мелочь, по сравнению с тем, какой труд и любовь были вложены в данный проект.
心より感謝申し上げます❤️

Response from developer

Thanks so much for the kind words about the app! I'm not sure I totally understand the issue you're describing. I wonder if it's something specific to the Russian translation that I haven't noticed because I don't speak Russian? I would love to dig into this and figure out how to fix it for you. Would you mind reaching out to me at support@nihongo-app.com with a screenshot of the issue? Thanks!

Un outil incontournable pour tous ceux qui veulent apprendre le japonais.

Avec ses multiples fonctionnalités, cette application qui est bien plus qu’un dictionnaire est mon compagnon de tous les jours dans l’apprentissage du japonais. Bravo!

Is Nihongo free to use?

The app offers a freemium model. While some core dictionary and search functionalities are available for free, advanced features like audio pronunciations, photo lookup, the reading assistant, and enhanced flashcard capabilities require a 'Nihongo Pro' subscription.
