IBJJF vs BJJ Reaction Timer

The official mobile app of the International Brazilian Jiu-Jitsu Federation (IBJJF) offers athletes a convenient and reliable way to access and manage their membership information. Serving as a digital version of the IBJJF membership ID card, the app displays key details such as the athlete’s name, affiliated academy, and current belt rank, making athlete identification and event check-ins more efficient while providing access to exclusive athlete benefits. To enhance this experience, the app integrates with Apple Wallet, allowing athletes to securely add their IBJJF membership card and access it anytime, even offline, for faster identification at IBJJF events. Featuring push notifications, the app actively reminds athletes about important account updates, such as upcoming membership expirations, ensuring uninterrupted access to IBJJF services and benefits. With these features, the IBJJF app provides a dynamic and connected experience that keeps athletes informed, engaged, and competition-ready.

BJJ Reaction Timer is a clean, distraction-free round timer designed specifically for BJJ practitioners. Configure your round length, number of rounds, break time, and warm-up period — then hit start and let the app run your session. Audio cues signal the start and end of every round so you can stay focused on the mat, not the screen. An optional **Random Reaction** mode introduces unpredictable prompts during rounds, helping grapplers simulate live rolling conditions and sharpen reactive decision-making. Named presets let you save multiple timer configurations (e.g. *Sparring*, *Drilling*, *Competition Prep*) and switch between them instantly.
