ContractionTimer.io is an ad-free contraction timer and tracker for iPhone, iPad, and Apple Watch, trusted by over 500,000 parents. It is used during labor to measure contraction duration, frequency, intensity, and interval. Get alerts based on the 5-1-1 rule. Your partner or doula can follow contractions live on their own phone. Family follows through a private link in any browser. No ads. No pop-ups during labor. No account needed to time contractions. Contraction timing works offline. HOW TO TIME CONTRACTIONS 1. Tap when a contraction starts, then tap again when it ends. 2. See contraction duration, frequency, and interval. 3. Record how strong each contraction feels. 4. Get an alert when your timing pattern meets the 5-1-1 rule. 5. Use the "Call my provider" button to contact your care team. Time contractions from your Apple Watch or Lock Screen without unlocking your iPhone. WHAT DOES A CONTRACTION TRACKER MEASURE? Duration is how long one contraction lasts. Frequency is the time from the start of one contraction to the start of the next. Interval is the rest time between the end of one contraction and the start of the next. ContractionTimer.io records these timings automatically as you tap. Contraction strength is based on your own rating of how each contraction feels. Review your history to see changes in timing and reported intensity.

The 5-1-1 rule means contractions start every 5 minutes, last 1 minute each, and continue for 1 hour. ContractionTimer.io alerts you when your recorded contractions match this pattern, helping you discuss next steps with your healthcare provider. A timing pattern alone cannot confirm your stage of labor. Some providers use 4-1-1 or 3-1-1 instead. Ask your provider which pattern applies to you. WHEN SHOULD I START TIMING? Start recording when you notice contractions and want to track their pattern. Review duration, spacing, and your reported strength to share a clear history with your care team. PRIVACY No account is required for contraction timing. Your contraction history stays on your device unless you choose to share it with your partner or family. Available in 18 languages on iPhone, iPad, and Apple Watch. ContractionTimer.io is not a medical device. Alerts follow general timing guidelines such as 5-1-1 and do not replace medical advice. Always follow your healthcare provider's guidance. ------- Contraction Tracker & Timer App is available on iPhone, iPad & Apple Watch.
