Waiver software for jiu-jitsu gyms

WaiverKit is digital waiver software for jiu-jitsu gyms: trial students, drop-ins, and members sign on their phone or a front-desk iPad before they step on the mat. Minor signing routes to a parent, injury history is captured, records are searchable for insurance.

Trial students walk in for a free class. They scan a QR code, sign on their phone, put their gi on. You keep rolling.

Signs and answers a 3-question injury check on their phone

Coach sees a green check before the warm-up starts

Trial class signups stop leaking

A trial student who shows up 5 minutes before class shouldn't get stuck filling out a PDF. Scan, sign, on the mat. You convert more of them because you stop losing them at the desk.

Parent consent without the phone-tag

Kids' programs can't run on last-class-of-the-day phone calls. Parents sign once, from wherever, and the signature is on file for the whole membership.

Injury history where your coaches will find it

Capture prior injuries and medical notes on the waiver itself. Coach pulls up the student record before a round, sees the bad knee, adjusts. That conversation used to happen after the injury.

Questions

Common questions from jiu-jitsu gyms

Can we send the waiver with our trial-class booking email?

Yes. Embed the QR code or signing link in your booking confirmation. Most gyms see 60-70% of trial students sign before they arrive.

How do we handle under-18 students in the kids' program?

Parents sign once from their own phone. The signature is linked to the student and stays valid for your whole membership period. You set the renewal window.

Can I export waivers for my insurance renewal?

Yes. Filter by date range and export the whole batch as PDFs or a CSV. Insurers usually accept the signed PDFs directly.
