Contraction Timer
Track your labor contractions in real time by tapping one button when a contraction starts and again when it ends. This tool records the duration of each contraction and the frequency, the time from the start of one contraction to the start of the next, which together are the numbers your provider usually asks about when deciding whether it is time to head in. It keeps a running log of your recent contractions and shows rolling averages so you can see whether they are getting longer, stronger and closer together, the classic pattern of active labor. A common guideline for a first baby is the 5-1-1 rule, contractions about five minutes apart, each lasting about one minute, for at least one hour, but always follow the specific instructions from your own care team. Everything runs locally in your browser with nothing sent anywhere, and this is general information, not medical advice.
How to use Contraction Timer
- Tap start when a contraction begins.
- Tap stop when it ends.
- Read the running duration, frequency and interval between contractions.
