User Reviews

Judo Reference is a highly valued, ad-free reference tool that organizes techniques by belt and helps users learn English/Japanese names, saving time and aiding revision. It is praised for reliability and ease of use, with strong visual aids. However, multiple reviews flag inaccuracies in technique naming, suboptimal video/animation quality, and limited quiz customization across belt systems, suggesting targeted improvements in accuracy, media quality, and configurable quizzes.
Pros
  • Comprehensive, well-organized reference to Judo techniques (categorized by belt level, easy to navigate).
  • Saves time and enhances learning by helping users memorize English and Japanese names and test their knowledge.
  • Ad-free, straightforward, stable app with a reliable reference experience.
  • Useful visual aids (images/stills) that support quick recognition and study.
Cons
  • Some technique names are inaccurate or mislabeled (in multiple entries), leading to confusion.
  • Video/animation quality and clarity could be improved; frames can be stilted, making fine details hard to discern; users request fuller animations.
  • Quizzes and belt-system customization feel limited (harder options, fewer localization options, potential to reveal answers too easily).

I love this app. It saves me time looking up a technique in a Judo book or searching YouTube. Great for studying Japanese names before a test.
