User Reviews

KanjiBox is a feature-rich, all-in-one Japanese study app that many users rely on for years, especially for kanji writing practice (KanjiDraw) and customizable study lists. Its strengths include multi-device syncing, an affordable price, and strong writing drills. Common complaints center on stability issues, UI/UX changes like large fonts, a limited in-app dictionary, and a desire for more grammar content.

Pros

All-in-one Japanese learning tool for kanji, vocab, readings, and drills with cross-device syncing, frequently praised as replacing other apps.
KanjiDraw (and KanaDraw) handwriting practice strengthens recall and is considered worth the price.
Easy creation and sharing of custom/public lists; quick to build study sets and use public lists.
Long-term effectiveness and reliability, with years of use across devices.
Good value at a one-time price with no heavy subscription.

Cons

Frequent crashes and stability issues, including launch crashes and long-running crashes.
UI/UX issues in recent updates, such as oversized reading fonts on smaller screens.
Limited in-app dictionary; not a comprehensive dictionary, prompting use of external resources.
Grammar content is lacking or hard; requests for more grammar practice sets.

I’ve graduated from college with the Japanese major, but I have still been using this app and the website to keep up with my language abilities and study higher level kanji for probably 15 years now. I just reopened the app on a whim because I was recommending it to someone else and there’s a surprise update?!?! It looks amazing now, thanks for all your hard work over the years!

I've been using this app for the better part of a decade to help study or refresh my knowledge on kanji and vocab. I really like the example sentences - you can click on any word after answering the question and get a bunch of examples and usually every part of the example is broken down in case there's words you can read or don't know. 皆さん、頑張れ！！！

Downloaded this program years ago…must have gotten distracted. Lots of cool additions. It’s just a great program for learning and reviewing Japanese. Thank you!
