Judo Kata Tournament Manager

Browser-based software to organise, score, and display judo kata competitions from one laptop on the local network — built for organisers, judges, and the hall.

Why it helps

For organisers

Set the event name, logo, included kata, and scoring rules once in Config
Add competitors and judges by hand, import them from CSV, or pull competitors from this year’s IJF kata events on Judobase
Run the draw, seat the panel, and assign performances to mats
Print a full-day PDF pack — or one kata — when you need paper at the table
Lock clerk pages with a PIN, including Config and the scoring audit; share public links for tablets and projectors
Keep each event in its own SQLite file; no internet required on the day

For judges

Open a seat URL that shows your name, the kata, and tori and uke on the mat
Tap small, medium, and big mistakes, forgotten techniques, and ± corrections — each tap is saved at once
Submit when the kata finishes to lock the seat; the tablet waits for the rest of the panel
Sit as shadow to record a score that is stored and ignored in the total
Use dark mode and zoom under hall lighting; the clerk can unsubmit if you sent too soon

For the hall

Put the announcer board on a hall screen: current tori and uke, judging team, who is on deck
Project live results that update as judges tap, with provisional points and an in-progress marker, and can rotate through kata
Switch English or French on the live screens
Spectators can use public links without the organiser PIN

See it on the day

Tablets, hall screens, and paper packs are part of the same event. The how an event runs page walks through config, the draw, mats, and every screen below.

Judge tablet for seat 2 showing the named judge, tori and uke, and technique scoring grid with S M B F and plus minus controls — Judge tablet seat

Live results display for Nage-no-Kata showing ranked pairs, points, and an in-progress marker on a pair still being scored — Live results display

Announcer board for Tatami 1 with current tori and uke, judging team, on-deck pair, and later schedule including a break — Announcer board

Printed PDF scoresheet with event header, pair and judge details, mistake checkbox grid, total, and signature boxes — Pair×judge scoresheet

See how an event runs

Scoring you can trust

Choose EJU, kata-judge/BJA-style, or IJF in Config. The same tablet marks produce the event total — forgotten techniques, drop rules, and tie-breaks included — without rebuilding a spreadsheet at the venue.

The system has been tested against the senior categories of the 2024 Silesian Open Judo Kata Competition.

On-site support

Lance can travel to your competition and run the system on the day — in the UK or internationally — including a parallel run beside your existing process. Typical fee £100 per day plus travel costs.

On-site kata scoring support

Interested in trying it?

The software is under active volunteer development and is available for demos and supervised test use. Online walkthroughs, sandbox access, and parallel runs beside an existing scoring process are all welcome.
