TickTock is an open-source Android app that helps set the beat of a pendulum clock.
KEY FEATURES:
• Real-time beat tracking from microphone audio
• Period measurement in milliseconds
• Asymmetry measurement in milliseconds and percent
• Gauge visualization from -25% to +25%
• Color-coded asymmetry indicator for quick feedback
• Start/Stop acquisition with live status text
• Live G: indication of the automatic gain-control multiplier; the value freezes after fit lock
• Beat-log export with 0.1 ms precision
USAGE:
• Set the initial guess period (default 1200 ms)
• Tap Start and grant microphone permission
• Wait while TickTock locks to the beat
• Read Period, Asymmetry [ms], and Asymmetry [%]
