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.
