I have been back and forth trying to learn Japanese, and although there is a lot of resources, it is difficult to keep material with you, and it is much more difficult to create a comfortable, N+1 progression.
Furthermore, a lot of learning apps simply present you information, and make you do a lot of the work, like quizzing yourself and learning grammar/vocabulary manually.
Monday has a promising system similar to Duolingo, a slick web and native app interface, and offers three levels of mastery when most apps dont take you past beginner. For example, you get to switch between romaji and kana. Most apps dont even give you a choice to use kana!
I bought the complete language pack at their insane discount, and with just the little time I spent, it has been worth every cent.
Currently, the app has no way to connect to your online account, which is not necessarily a deal breaker, even if you bought the package in the online store. I am assured this will be fixed in the next, or next few updates, a promise that has completely won me over.
Learning a language can be difficult, but teaching one is an even harder task. I love to see what Mondly is doing to move the needle in language learning!
