About

MMA Round Timer

Features
Read full description

MMA Timer is a fast, reliable interval timer built for combat sports training. Rebuilt from the ground up in 2.0: go from launch to a running timer in two taps with Quick Start, then keep training while your phone is locked — your rounds and countdown stay live on the Lock Screen and Dynamic Island. Create sessions with blocks, rounds, rest, and optional phases inside each round (e.g., Boxing → Kicks → Clinch), or start instantly from a preset. Features • Quick Start: rounds × work × rest + one-tap format chips → GO • Interactive Live Activity — pause, resume & skip from the Lock Screen and Dynamic Island • Background-correct cues that fire on time when locked or pocketed • Real boxing bell plus synthesized cues, with distinct phase-change and round-end sounds • Phases inside rounds with a clear animated active-phase indicator • Wall-clock timing with zero drift and a color-coded draining ring • Final-10-second pulse and flash warning • Drag & drop to build and reorder sessions and blocks • Session history to track completed workouts Whether you're doing pads, bag work, wrestling, BJJ flow rounds, or conditioning, MMA Timer keeps the clock simple and reliable.

About

BJJ Reaction Timer

Features
Read full description

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.
