Highly recommend!

I love this app so much because it covers everything you need to master japanese! It has lessons for vocabulary in different scenarios, and lessons for hiragana, katakana, and kanji!! For me, the app has never crashed! Yeah sometimes the audio processing lags a bit, but what app doesn’t have glitches every once in a while? Also, the customer service is great!!! I had a question, so i emailed it and someone replies within the hour! And an actual person! Not done programmed response. Sometimes having only 3 free lessons a day is slightly annoying, because whereas I understand that you can’t give unlimited lessons for free, it would be nice to have the flash cards unlimited or the lessons you’ve already completed. Overall very great for anyone starting to learn japanese.

It's Okay- Needs a Support Option

I use this app in addition to several others, Kaizen is probably my least favorite. You have to pay to really do anything in the app which is fine if you're serious about learning, but the further you get in the lessons the more I've seen typos from incorrect words, genders, spellings & even the app marking things as incorrect that are not.
It would be better if there was a way to "report" such as Duolingo has when you come across errors within the app. I can only imagine how many people have seen these errors and taken them to be true. One lesson I saw どけい being translated as clock when it is in fact とけい. When using the word "father" the speakers constantly referred to father as "she" among other errors. Lastly, the hints/suggestions it gives you for responses are very restrictive and leave little room for you to practice outside of exactly what they want you to write. The app is definitely helpful for learning but I wouldn't use it as my only method for learning Japanese. Bunpo is great for people looking for something other than Kaizen to learn.

Too many flaws!

Correct answers, including sentences from the suggestions, are frequently randomly marked as wrong, often causing loops that make lessons unfinishable. Lessons sometimes hang, forcing you to restart them. While some activities give you some word choices (such as different colours and names), others only allow you to say a very specific sentence (e.g. 'I hate dancing' or 'I don't like singing') which may be very different than how you actually feel about the topic. In some activities, the app marks gramatically correct first-person Spanish sentences as wrong when you omit 'Yo.' The English translations of both Spanish and Japanese phrases also have several misspellings and sometimes wrong grammar. The streak randomly goes down to 0 even when you meet your daily goal the previous day. The customer service takes too long to respond, sometimes forgetting to do so altogether. I have sent feedback regarding the streak problems and the team has kindly but unsuccessfully attempted to fix my streak three times. I do not recommend this app for learning Spanish and/or Japanese.
