RunnerSim2 is a lightweight training tool for timing and reaction work.
• Start via audio trigger (bat/ball contact) or manual trigger
• Select Preset, Random, or Manual countdown duration
• Hear metronome cues spaced evenly through the countdown
• A clear horn signals zero
• Turbo mode shortens all times by 10%
• Safety lockouts prevent re-triggering during a countdown (plus a short cooldown after)
• Reset always returns to a clean default state
Designed for fast reps, consistent timing stimuli, and minimal UI friction.
