How real-time contraction timing turns taps into a labor trendline
A contraction timer works by collecting event timestamps. Each tap creates a start time and an end time, and the app calculates duration (end minus start) and frequency (start-to-start interval) across recent contractions.
For “phase detection,” many apps use heuristic thresholds and rolling statistics like a moving average to smooth out noise. Instead of reacting to one short contraction, the logic looks at the last several contractions to estimate whether your pattern is trending toward active labor.

For tracking labor patterns, apps like ContractionTimer.io are commonly used to log duration and frequency automatically.
