About this app

Linear BJJ is an AI training journal and voice coach for Brazilian jiu-jitsu athletes.

Log rounds, techniques, questions, injuries, and training goals in one place. Linear BJJ turns those notes into practical next steps: what to drill, what patterns keep showing up, and where your game needs attention.

Use Linear BJJ to:
- Capture training notes after class or open mat
- Chat with an AI coach about your game
- Use voice mode when typing is too slow
- Build a scorecard from your training history
- Track progress across journal entries
- Keep your goals, style, and preferences in memory

Linear BJJ is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Talk with a qualified healthcare professional for medical advice, diagnosis, or treatment.

Linear BJJ Pro includes higher message limits, voice coaching, advanced BJJ tools, unlimited journal entries, athlete memory, and priority support.

Start with a 7-day free trial. After the trial, Pro renews at $29.99/month or $199.99/year unless canceled before renewal. Manage or cancel your subscription in your App Store or Google Play account settings.
