Question 2

Is Judo Kata free and do I need an account?

Yes. The app is free to use with no account required. Practice data stays in your browser (IndexedDB). You can export, import, or reset a JSON backup at any time.

Question 3

Does the app include official kata videos?

Accepted Answer

No. There is no bundled default YouTube catalog. You paste your own reference video URLs and set technique start/end timestamps for practice playback.

Question 4

Are practice judging scores official competition results?

Accepted Answer

No. Practice judging uses IJF Kata Commission–style criteria as a training aid for partners and coaches. Scores are not official IJF or federation competition results.

Cloud Sync is a planned optional paid plan for cloud backup and multi-device sync of personal practice metadata (not YouTube videos). Free local use stays. Planned prices are US$2 per month, US$11 per six months, or US$20 per year. It is waitlist-only and not for sale yet. Details: https://judo-kata-tool.the-fortitudes.com/cloud-sync
