I payed for the year to use the app. For some reason the quiz function doesn’t respond to to touch screen. When I try to select an answer (any answer) it does nothing and I can’t continue. The option to practice writing works fine. ### 4/5 — Corrections and keyboard issues mar interesting app *2022-08-03, version 3.4.8* Corrections often correct the wrong part of a wrong answer, telling you that you got something wrong that you didn’t and not noticing the actual error. Also, there way it handles submitting answers makes it impossible to use a hardware keyboard. There is no submit button unless you have the onscreen keyboard. ### 3/5 — It's Okay- Needs a Support Option *2022-03-21, version 3.4.6* 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. ### 3/5 — It’s okay but could’ve improved *2022-01-01, version 3.4.2* It’s good for a first time use, until you find out that you have to pay to learn a language. Right now I’m trying to learn Japanese bad Korean, but sadly Korean is not in the list of things you can learn on this app. It’s complicated to have to pay for something like educational things and to be honest it’s kinda upsetting that I need to pay to learn a new language. I’m not saying that you should download this app but just know that you have to pay 7.99 monthly just to learn something new. You most likely would be better off using Duolingo if you can’t afford to pay monthly ### 4/5 — Keeps crashing mid lesson *2021-12-27, version 3.4.0* I’ve bought the yearly pass. I was excited to reintroduce myself back into learning Japanese again. But it keeps crashing. I will make a written log soon. I really hope this can be fixed because I love the style this is done in. It is rejoicing my mind a lot and understands my dialect really well. Good luck programmers for our sake as much as yours. ### 4/5 — Plz fix *2021-11-05, version 3.3.8* App is great, just which the app mic can pick up exactly what I’m saying instead telling me too constantly repeat over and over and over again. ### 3/5 — Voice problems *2021-09-24, version 3.2.10* Not sure if it’s my phone or what but apparently this will not pick up my voice when I speak because it continually tells me to redo stuff because it will not pick up everything I say. ### 4/5 — Good *2021-09-13, version 3.2.10* So far I think this app can help a lot, but I don’t want to subscribe, at least not now. It would be better if I could do more stuff without paying, or at least get a better feel if I can learn a lot from this app ### 4/5 — Amazing app🤩 *2021-06-21, version 3.2.0* This is a very good app, it has amazingly surprised me how awesome this app is. This app is not like any other, and its nothing compared to Dalingo. That is because Kaizen some how makes things way more memorable, based off the voices. That may not make any sense, but I do highly recommend this app to learn different language. So far I have started Japanese and it’s starting off great!!😮‍💨 ### 3/5 — I finished the lessons now what? *2021-06-16, version 3.2.0* I finished all the lessons and I wanted to review the Flashcards. You only can do 10 at a time and often they repeat the same 10 over and over. Will you ever allow users to control how many flash cards they view at one time? That would definitely help with the longevity of the app. ### 3/5 — Great Lessons... but kind of disappointing *2021-05-02, version 2.2.98* I have been wanting to learn Japanese for a long time and this is the first app I have found that I actually like. The lessons are great and really improved my knowledge but it is disappointing you only have 1 lesson a day u less you pay. You shouldn’t have to pay to learn! ### 4/5 — So confused *2021-04-26, version 2.2.98* I feel like must be missing something obvious but in my flash cards it says I have 160 “learning”, 96 “ready”, and 0 “mastered”. I’ve done these flash cards dozens of times now, and the numbers don’t change. How do I get those other 96? How do I “master” them? Otherwise I love the app so far. Sometimes I feel like the speaking exercises get too complex too quickly though. It would be cool if the flash cards had a speaking component where you just say the one word/phrase and it grades your pronunciation. ### 4/5 — It’s ok but I need help understanding *2021-04-25, version 2.2.98* Hi!Im new to this app and I’m trying to do lessons because I did one yesterday and I tried to do it today but it says I have to subscribe to finish or wait again??So if you can respond and tell me if I need to subscribe to finish and I understand that you don’t give free lessons but I just need some help. ### 3/5 — Cool app *2021-04-01, version 2.2.92* I like this app but wish it gave a little more instruction on how to practice - should I be repeating the conversation drills? Also, I wish the audio for the flash cards would play automatically instead of having to manually hit the play button. ### 4/5 — Observations and suggestions *2021-03-29, version 2.2.92* This is a really great app. The best for language learning I’ve ever used. The only problem is that there is a bug/glitch where the app hears me correctly but doesn’t register what I said as being correct, even though it’s the exact thing it told me to say. They I have to close the app and leave it for a while then hope it works when I try again. It’s really random. **Developer response:** Hi there! Sorry to hear about your issue. Please can you email to hello@kaizenlanguages.com so we can look into this for you? ## Most critical reviews (10 lowest-rated) ### 1/5 — This thing speaks nonsense “Japanese” and can’t understand konnichiwa *2022-12-21, version 3.4.12* On the very first lesson, it wants me to say konnichiwa. I do I say it right. It doesn’t understand me. It asked me to repeat. So I gave the thing to my native Japanese speaking wife and it couldn’t understand her either. So we couldn’t get past that at all. I’m glad it was free. really the Japanese that it says or writes is complete babble. If the developers want to contact me or respond, so I know I’d be happy to entertain any suggestion and update my review and rating accordingly if necessary. Otherwise it’s getting deleted. **Developer response:** Hi! Thanks for your feedback. I would love to learn more about your experience and how we can prevent this from happening in future - please can you email us at hello@kaizenlanguages.com with more details? ### 1/5 — Too many flaws! *2021-11-02, version 3.3.6* 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. ### 1/5 — Worthless without payment *2021-10-20, version 3.3.2* The app advertises three free lessons a day but you actually only get two. In addition, the flash cards you “unlock” are also actually locked behind this restriction as well. The writing lessons also are locked. Basically all you can do for free is say 4 sentences a day, twice. If you want to make this a paid program, make it paid, but there’s no reason for it to be a subscription or for the free tier to be so limited - you may as well not have one. ### 1/5 — Not good for advanced learners *2021-09-26, version 3.2.10* So, I really wanted to test my speaking with this app, but whenever I communicated something more than what the AI was asking for it marked it as wrong! This might be good for beginners, but I wish that it could just place you at a certain level and let you speak to your heart’s content!! Also, I did not want to subscribe and the 2 lessons were kinda boring. ### 1/5 — Non functional product *2020-10-30, version 2.2.62* Worked wonderfully until I subscribed then suddenly even though it correctly types what I say in the text box as I say it the instructor never understands what I’m saying. I have taken years of classes I am positive this is the programs fault especially given it writes what I say correctly then fails me. Update mizuke inoue 10/12 says please ask to buy this item. When you answer it corrects you and says try asking how much the item is. When you answer it shows the original question about purchasing. What is the answer you’re looking for here? **Developer response:** Hi there! Thanks for letting us know about this issue! We’ve updated the AI based on your feedback so please have another go and let us know how you get on :) if you have any more feedback, please don’t hesitate to reach out to hello@kaizenlanguages.com ### 1/5 — Needs work... *2019-09-28, version 2.1.8* I made an account today, and after two lessons you have to pay to continue learning. I have tried to figure out how to delete my account, and it is not clear on how to do so. I checked their website and it says to “Navigate to the Settings/Account Page in the app. And scroll to the bottom and select delete.” I have tried to do this, but the problem is that there is no button to delete the account. So I’m wondering how to delete my account. ### 2/5 — Voice recognition is terrible *2022-09-07, version 3.4.8* Great promise, but the voice recognition doesn’t work very well at all- often you will say exactly the phrase it wants, but it’ll just say ‘repeat please.’ No matter what you do- I can’t read kanji yet so I’ll bet it’s not hearing what I’m saying correctly despite the fact that I know my pronunciation is good. ### 2/5 — Only useful thing is flash cards *2021-12-17, version 3.4.0* Trying to speak to this app is like trying to talk to a brick wall. It doesn’t even let you finish 99% of the time and tell you that you are wrong on a part you never even got to say. The 1% of the time it does let you finish it is so far off it isn’t helpful ### 2/5 — Very inconsistent and the lessons don’t work. *2021-10-09, version 3.3.0* Imma be straight to the point. I love the app, when it works it is the best app for learning Japanese out there. But…the lessons break a lot. I’m still working with Mizuki and the Nationalities lesson just won’t let me get past saying my own nationality. At first I thought I was spelling it wrong but it’s just not even accepting anything I put. Even when I put in the exact recommendation or when I type it in the romaji translation it still just asks me say it again. ### 2/5 — Good but there are some glitches *2021-02-13, version 2.2.82* I use this app and LingoDeer together since it’s hard getting proper language practice with just one app. This app teaches you written Japanese which is not how it’s spoken. I don’t know if maybe this is noted later or not. I also noticed some answers it would not take even though it was correct. For example, it wanted me to say “私は田中です。” and I did but I wrote the name in hiragana. It kept telling me that sentence was wrong. This has happened more than once and is a bit annoying. Anyone who has been forced to use an online math program knows this pain. There are also times where it asks you to make a sentence like “私の父は____さいです。” and then do another one for a different family member. It then immediately says you are wrong because it wanted the father sentence again. If it doesn’t get fixed I will most likely delete the app. **Developer response:** Hi Eliforte, Thanks for your feedback. This has been passed onto our Japanese language specialists to look into. If you have any more feedback, please let us know at hello@kaizenlanguages.com :) Any and all feedback is welcome ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2022-03-14, version 3.4.4* This is a great app, I’m stuck on the second tutorial and apparently it’s in a loop because I have a slight speech impediment. So saying “sayonara” is what gets me. Lol, I wish there was a way to do some kind of way to adjust speech recognition. ### 5/5 — Kaizen review *2022-01-21, version 3.4.4* I love this app so much!!! This app is really helpful with learning Japanese, it has made it way easier for me to mesmerize the katakana. I love how it can help you have normal conversations too!! ### 5/5 — Try it *2021-09-11, version 3.2.10* I love this so much you learn Japanese better and it’s fun writing you can learn Spanish but I wish you had more no just Japanese and Spanish I like doing Japanese so when I go to Tokyo or japan I will know how to speak the language ### 5/5 — Highly recommend! *2021-06-14, version 3.1.2* 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. ### 5/5 — Great app *2021-05-21, version 3.0.6* I like the fact that it reviews your speech and gives you suggestions on how you should say it ,it’s been really helpful and I feel like I’m learning quicker ### 5/5 — Really learn to speak and listen *2021-05-08, version 2.2.98* The beautiful thing about Kaizen is it forces you into conversation immediately but holds your hand the whole way. And self study blocks are built right into the app as well. ### 5/5 — Amazing *2021-03-18, version 2.2.92* This app is amazing for pronunciation and reading. But the captions should not only have what you have to say in Japanese, but also the sound you have to make in English letters. ### 5/5 — Great app but some things need to change *2021-02-27, version 2.2.84* The app is great with all the interactive chats and writing but the only 3 lessons a day is unreasonable. I understand that you can’t just give away free lessons but it would be great if you can at least make the flash cards and the lessons you already did unlimited. It makes sense to make new lessons and writings limited to 3 times a day unless you purchase premium, but the flashcards and the already completed lessons should be unlimited. Please consider doing that for people will be more likely to keep the app ### 5/5 — Path to Japanese *2021-02-21, version 2.2.84* I actually really like this app. It forces me to actually speak Japanese and I think that’s really cool and is an easier way to learning Japanese. Now all you have to do is stay consistent. ### 5/5 — Love it *2020-09-07, version 2.2.54* I am planning on being a transfer student in about two years and may I just say this app has already helped me so much in learning Japanese I have tried other apps and they just could not fit my learning style but this gets a 10/10 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
