Bunpro vs Renshuu (2026): Which One Do You Need?
Short answer: Renshuu is the wider tool, and you can study on its free tier for years. Bunpro is narrower and deeper: it drills grammar by making you type the form into a blank. Pick Renshuu if you want vocabulary, kanji and grammar on one schedule, or if budget is tight. Pick Bunpro if grammar is the thing you keep failing. Neither one reads a sentence you wrote yourself, which is where most N3 learners get stuck.
We build a JLPT practice app, so we are not neutral. We checked Bunpro's pricing page and Renshuu's public pages in October 2026, and we say below where we could not read something. We also list what each app does better than we do.
What each app actually is
Renshuu is a general study system. Its own front page promises to adjust what you see "down to each individual kanji", so a word can show furigana only on the characters you do not know yet. It mixes question types (multiple choice, writing, drag-and-drop, listening) instead of "flipping a card over repeatedly". Lessons come as curated packs or as the thousands of staff-made and user-made lists. There is a gamified layer, with a mascot who fights monsters as you study, and the page says all of it can be switched off. Vocabulary, kanji, grammar and sentences share one dictionary that tracks what you know, and there are iOS and Android apps.
Bunpro is a grammar course driven by spaced repetition. The pricing page lists write-ups for over 900 grammar points, over 10,000 example sentences that build on earlier grammar, native audio on every example sentence, references to textbook page numbers, 120+ graded reading passages and a Cram mode for exam week. It also now bundles vocabulary decks, with 100,000+ context sentences. It syncs with WaniKani: it can mark your burned WaniKani items as known. There are iOS and Android apps here too.
What a review actually feels like
This is the difference that decides the question for most people.
A Bunpro review shows an English sentence and a Japanese sentence with a gap. You type the grammar form that fills it, conjugated correctly. Suppose the gap needs 〜によって and you type 〜に対して. The two look interchangeable in a flashcard, and typing is where you find out you cannot pick between them. A "ghost" feature re-shows items you missed, and the answer list accepts alternate correct forms, so a valid sentence is not marked wrong.
A Renshuu quiz is varied by design. One session can ask you to choose a meaning, type a reading, drag pieces into a sentence and answer a listening question. That variety builds recognition across many words quickly. It is less targeted at the moment where you have to produce one specific grammar form with nothing to pick from.
Neither is better in the abstract. Recognition across a large vocabulary and production on a small grammar list are different jobs, and the JLPT tests both.
Side by side
| Renshuu | Bunpro | |
|---|---|---|
| Main job | Vocabulary, kanji, grammar and sentences in one system | Grammar first, with vocabulary and reading added |
| Grammar review | Mixed question types | Type the form into a sentence blank |
| Free tier | Permanent; users report the free tier covers the study content | "Free Forever" at $0; exact free limits are not itemised on the pricing page |
| Paid | Pro, monthly or lifetime; logged out we could not read the price, so check it on the site | $5 per month or $150 one-time (read from bunpro.jp/pricing, October 2026) |
| Trial | Users report a free Pro trial emailed after you have studied for a while | 30-day Premium trial on every new account, no card |
| Textbooks | Lesson lists keyed to common textbooks | Page references to textbooks inside each grammar write-up |
| Audio | Listening question types | Native audio on example sentences |
| Reading | Sentence-level inside quizzes | 120+ graded passages |
| Feel | Colorful, customizable, lots of surface | Plain, dense, one job |
What Renshuu is better at
- Cost for a learner with no budget. You can run it as your whole routine on the free tier. Users on its forums say Pro mostly adds ways to study the same material, such as listening questions and extra kanji question styles, and not new content.
- One queue instead of three apps. A study routine usually dies from fragmentation. One schedule for words, kanji and grammar is easier to keep.
- Tuning to your level. Showing furigana only on kanji you have not learned means reading practice never turns into a wall.
- Staying fun. If you will open a slightly silly app daily and not open a strict one, the silly one wins.
What Bunpro is better at
- Forcing production. Typing the form, not choosing it, is the closest either app gets to the JLPT's grammar section, and it is the main reason to pay.
- Explaining near-synonyms. Each write-up shows how a form is built and links related grammar, so confusable pairs stop blurring.
- Reading beside the grammar. Graded passages sit next to what you just drilled.
- Cramming on purpose. Cram mode is built for the final week, which most SRS apps ignore.
Which to pick
- No budget: Renshuu. It is not a compromise pick.
- Vocabulary and kanji are the wall: Renshuu.
- Grammar is the wall, N4 to N2: Bunpro.
- Studying with Genki or Tobira: either works. Renshuu follows your lessons by list; Bunpro tells you which page to open.
- Not sure: use the Bunpro 30-day trial and the Renshuu free tier side by side for a month, then keep whichever you actually opened. Many learners end up running both, Renshuu for words and Bunpro for grammar.
If you are also comparing against flashcards or a kanji tool, we wrote the same kind of comparison for Bunpro vs WaniKani, Renshuu vs Anki and Bunpro vs MaruMori.
What neither app does
Both are recall engines. They build raw material well. Neither one asks you to write a free sentence, and neither one tells you what is wrong with a sentence you wrote. Plenty of learners finish a Renshuu queue or a Bunpro path, sit the exam, and find that picking or filling in a form is easier than producing one from scratch.
Where BetterLingo fits
We build BetterLingo, a JLPT practice app that marks written answers. You type a full Japanese sentence and it explains what is wrong, in English. You can also paste any sentence into our free Japanese grammar checker, no account needed, or take the free JLPT level test to see where you stand.
We are not a replacement for either app. We are small and new. We have no mature SRS deck library, no textbook lesson lists, no kanji curriculum, no handwriting practice and no years of community threads. If you want a scheduler that drills you for years, use Renshuu or Bunpro. We exist for the step after: writing Japanese and getting it checked.
Next steps
If you are choosing between the two, start both free options this week and track which one you open. If you are already using one and still cannot write sentences, check a sentence you wrote and see what comes back. More comparisons are in the Learn hub, including Bunpro alternatives.
