Questions

What is Judochecker?

A free database of Judo practitioners. Members add their belt, their promotion history and their academy, and the community verifies it. 387 members from 29 countries use it to show their rank, find training partners and see where their lineage goes back to.

How does belt verification work?

Members who know you, like training partners, coaches and people you have competed with, vote for your belt. Votes from higher belts and verified members weigh more. When your profile has enough points it is marked as verified.

Is it free?

Yes. Creating a profile, getting verified and using the forum, statistics and training log is free. Certificates and ID cards can be ordered for a small fee.

Can I see who promoted a black belt?

Yes. Every profile shows its promotion history with the promoter of each belt, and the lineage explorer follows it back through the generations.
