About
A jiu-jitsu journal for Android. Log a class in 30 seconds (gi or no-gi, rolls, intensity, submissions), follow your belt and stripes with a goal for the next stripe and IBJJF minimum times, keep a 120+ technique notebook, and run a round timer that rings with the screen locked. Offline, no sign-up, no ads. On Google Play in Brazil now, more countries next.
AI Summary
Grau is an Android app designed for Brazilian Jiu-Jitsu practitioners to log classes, track belt progress, and maintain a technique notebook.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
