TickTock

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:

1. Set the initial guess period (default 1200 ms)


2. Tap Start and grant microphone permission


3. Wait while TickTock locks to the beat


4. Read Period, Asymmetry [ms], and Asymmetry [%]
