ContractionTrack

ContractionTrack is a free web app designed to help pregnant people track labor contractions. Users tap to start and stop timing each contraction, and the app records duration, frequency, and rolling averages. It alerts users when they reach the common 5-1-1 pattern (contractions every 5 minutes, lasting 1 minute, for at least an hour), which many healthcare providers use to determine when active labor has begun.

All data stays in your browser with no account required, no server uploads, and full offline functionality. The app includes guidance on when to seek hospital care and how to distinguish true labor from Braxton Hicks contractions. It can be installed as a home screen shortcut on mobile devices. Built with Lovable, according to the maker.
