User Reviews

Judokai is praised for clear, multi-angle technique videos and an easy-to-use quick reference with well-structured breakdowns. However, users report recurring crashes after updates, device compatibility issues (notably with iPhone SE), and problems with unlocking or accessing paid content. Support contact options are lacking, and there are requests for more content, including translations and additional forms. Overall, strong instructional value tempered by reliability and content breadth concerns.

Pros

Clear multi-angle demonstrations of techniques
Easy to understand and serves as a quick reference
High-quality video production and visuals
Structured breakdown of moves (kuzushi, tsukuri, kake)
Regarded as a go-to app for serious Judokas

Cons

Crashes after updates / frequent crashing
Compatibility issues on certain devices (e.g., iPhone SE)
Paid content unlocks not functioning / purchases not unlocking content
Difficult to contact support
Requests for more content (translations, kata/forms) / breadth of content missing

Recent reviews

Currently this app is running extremely slow. For example to view a video it’s taking me 5 min before it starts to play.
