About this app

A cute, ad-free, and enjoyable learning experience is waiting for you in the Renshuu community! The free version is unlimited: there’s no timer before you are forced to pay!

★ A path for every learning style and every goal ★
Whether you are getting started with the alphabets or have been studying for years, jump in exactly where you belong! Don’t waste time going through what you already know.

Renshuu maintains learning paths for most textbooks, the JLPT, Kanji Kentei, and for those who just want to learn. You can also carve out your own path! Our community has over 10,000 user-made lessons for even more focused learning.

★ Cute, relaxing, and fun ★
Our mascot Kao-chan is here to let you enjoy learning Japanese, whether it’s through collectible coins every time you quiz, a character that evolves as you learn, manga pages that you unlock, or hundreds of hand-made illustrations.

Additionally, we have both single and multiplayer games to help you keep your learning and reviewing fresh!

★ Personal service ★
We are just a two-person company - and we don’t use chat bots. That means that every question you have gets an answer directly from us.

★ Rich, in-depth materials ★
■ Vocabulary: over 15,000 native-recorded audio files, 17,000 hand-picked images, and 160,000 example sentences make understanding vocabulary a breeze. Our growing library of accent/pitch data can even help you with accent reduction.
■ Kanji: 12,000+ kanji, with no limits on what you can study! Over 2,000 colorful mnemonics help you to understand and retain the meanings.
■ Grammar: Over 800 different expressions, each complete with native-written model sentences, construction diagrams, audio, and over 7,500 hand-made quiz questions.
■ Sentences: Thousands of sentences complete with audio, divided by theme and difficulty levels.

★ A superior quiz system designed around Japanese ★
Our SRS-for-Japanese system doesn’t treat Japanese materials like flashcards to be memorized, and breaks every item down into individual components so you can understand, and not just memorize. Mastery schedules keep you studying only what you need to, pushing weaker materials to the front for you to focus on.

Dozens of different question styles keep things fresh, while a flexible input system (multiple choice, typing, or writing) lets you answer the way that you want to.

★ Customizable down to the last character ★
Renshuu doesn’t believe that there is a single way of studying that everyone should adhere to. Our expansive settings and customizations let you adjust the learning environment to what works best for you.

Would highly recommend this. A free(with premium, sure) language learning app that doesn't constantly ask you to pay, has a nice community, and has learning games to help supplement the lessons and quizzes? Literally exactly what I was looking for! Thanks, devs, and amazing work. To be completely honest, this is probably closer to a 4.5 than a 5.0, but that's still saying a lot when it comes to a learning app.

Thanks for your kind words! Indeed, we do have some premium tools, but they are 100% optional - you'll never run into a wall preventing you from studying more unless you pay. Should you have any ideas on how to make renshuu even better for you, do let me know! I'm always here at, or the ? button at the top of the app.

I have tried several language learning platforms over the years, both for Japanese and for other languages. Renshuu is the most comprehensive in presentation and rigorous in its practice schedules of any I have encountered. I appreciate that I can separately choose to focus on grammar, vocabulary, and writing tasks, and choose when/how I learn or review each lesson. The embedded dictionary has also been invaluable for reference when exploring the language outside the app.

Thank you so much for the detailed review! What we lack in a simple UI, we more than make up for with a crazy depth of features, customization, and content. As a long-time IRL teacher, I know that everyone has their own way of learning, so renshuu wants to help you realize that :) Reach me at if you need anything in the future!

this is by far the best app for learning japanese, I've seen on the app store. like 90% of the app is completely free and you dont feel like youre forced to buy a subscription if you dont want to. there are little to no adds, notifications are optional and even when you choose to recieve them, you get to pick what time you get them. the only thing is the interface was a little confusing to me at first because of the simplistic color scheme. overall 10/10 app. use this! not duolingo!

So glad you're enjoying it! We designed it specifically for a low-pressure, no-paid-requirements experience. We want you to enjoy it :) And sorry about the interface issues! If there was anything specific you wanted to point out, do let me know :) I'm always here at, or the ? button at the top of the app.
