When you learn a language, practice makes perfect and is the key to increase your fluency.

Just ok

I’m not particularly fond of the way the app functions, the lessons are the same each time but the Flashcards are totally different. It’s feels very rigid with the speaking because you can only respond with a certain set of answers. It’s a GREAT idea but for me it needs some buffing.

Hi Abianchetti,

Thank you for your review. There is greater variation in the lessons as you progress. We are also adding new topics all the time.

We would love to hear more from you at hello@kaizenlanguages.com

Great, when it works

Approachable, helpful lessons that generally are pretty cumulative and well designed. Unfortunately it’s extremely glitchy and crashes constantly, gets stuck in loops, the audio processing will say you’re wrong even if you pronounce things perfectly (I once recorded the set phrase being said by the app and played it back to it and it said it was wrong!), will give corrections and suggestions for other parts of other conversations or dialogue options, or won’t show the vocab word options so you have to use a separate app/program to look up or translate things ready.

I have been learning from it, but the level of technical dysfunction is crazy for a paid subscription service no matter how good the actual content is so I’ll likely be unsubscribing after this first month. The lessons are absolutely worth the $8 a month, but only if they work!

Needs fine tuning

I’ve been using this app (since I paid for it by accident and apple wont give me my money back) and it does need some work. In the Professions lesson, they ask you to reply “no or 家“ but when you reply with that, the answer is wrong and wants you to reply with yes. Also when adding -San to someone’s name like “Takahashi-San” it automatically replaces San with the number 3 making your answer automatically incorrect. It’s a cool idea, but the app needs some work...

Hi Justareview8299,

Thanks for your feedback! We’ll look into it and update the AI tutors to catch this for other learners :)

We’re dedicated to continuously improving the app and AI wherever possible to help Japanese learners like yourself.

With regards to the payment, have you reached out to Apple already? Unfortunately there’s nothing we can do from our side.

If you have any other feedback, please send us an email at hello@kaizenlanguages.com.
