CHECK

Sound familiar?

Paper records are hard to look back on

You keep team match scores on paper, and reviewing them later takes real effort.

The “why” never gets recorded

You know who won and lost, but the reasons behind wins and losses are never written down.

You want objective data on weaknesses

You want each player’s best techniques and losing patterns as data, not gut feeling.

FEATURES

What the Scorebook can do

Record ippon with one tap

Just tap the big Men, Kote, Do, and Tsuki buttons. Two ippon end a game automatically, and “Undo last” fixes mistaps.

Team results judged automatically

For 5-player matches from senpo to taisho, the result is computed in real time in the standard order: wins → total ippon → daihyo.

Tag the reasons behind lost points

Tag a conceded ippon with issues like “froze up”, “hands lifted”, or “weak zanshin” in one tap (or skip it).

Analyze on the results dashboard

Win rate, winning techniques, each player’s best and conceded techniques, issue-tag rankings, and losses by time of match — all totaled automatically.

Print as an A4 score sheet / save as PDF

One tap turns a recorded match into an A4 score sheet in the traditional paper format — ready to print or save and share as a PDF.

Use it from any device

Data is stored in the cloud. Record on your phone at the court, then analyze on a big PC screen later.

HOW TO USE

Getting started is easy

Register your own team once, and after that you just type the opponent’s name and tap to record. No opponent player registration needed.

STEP 1

Log in (no password)

Sign in with Google, or enter your email address and type the numeric code from the email you receive.

STEP 2

Register your team and players

Enter your team name and the players from senpo to taisho. You only do this once.

STEP 3

Create a match (opponent = just a name)

Enter a tournament name (optional) and the opponent team’s name. Your team is set automatically — pick the lineup and you’re ready.

STEP 4

Record each ippon

Courtside on your phone, tap Men, Kote, Do, or Tsuki for either side. Two ippon end the game automatically.

STEP 5

Results become charts automatically

Recorded matches are totaled on the dashboard: win rate, winning techniques, and each player’s strengths, conceded points, and issues.

FAQ

Frequently asked questions

Is it really completely free?

Yes. Both signing up and using the app are completely free. There are no membership fees, subscriptions, in-app purchases, or paid plans — every feature, from recording ippon to analyzing results, stays free.

Do I need to install anything or create an account?

No install is needed — it runs right away in your phone or PC browser (iOS / Android / PC). You do need to sign up with an email address or a Google account. With email you receive a one-time numeric code, so no password is required. The login email is currently written in Japanese — simply enter the numeric code it contains.

Will I receive a newsletter? Can I unsubscribe?

Signing up also adds you to the KOBUDO newsletter with kendo tips and offers, which is written in Japanese. You can unsubscribe anytime from the link inside the email. Using the app itself never costs anything.

Can other people see the data I record?

No. Your records are private and visible only to you. Your team's and players' results are never published.

Does it judge team match results automatically? Do I have to register opponent players?

Yes. For 5-player team matches (senpo to taisho) the winner is decided automatically in the standard order: wins, then total ippon, then a daihyo match. You record each ippon by tapping Men, Kote, Do, or Tsuki, and a game ends automatically at two ippon. Opponents only need a team name — no opponent player registration.

I don't know the paper scorebook notation. Is recording still easy?

Yes. Create a match and just tap the technique of each ippon. There is no notation to learn, and win rates, techniques, and per-player results are charted automatically. It is made for coaches, players, and scorekeepers — and it is free.

Can I print the score sheet or save it as a PDF?

Yes. Every recorded match can be shown as a traditional-style A4 score sheet (senpo-to-taisho pairings, techniques, and results) and printed as is, or saved as a PDF — useful for keeping and sharing tournament records.
