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.

Time your contractions with one tap, and know when to go. Wavesong measures your contractions against the rule your own provider gave you. Not a generic rule someone put in an app: the one you were actually told. Tap once when a contraction starts and once when it ends. Wavesong tracks frequency, duration and the start to start interval, watches the whole last hour, and tells you in plain words how close you are. WHEN TO GO, WITHOUT THE GUESSWORK - Your provider's own rule: minutes apart, seconds long, hours holding - The full hour is watched, not just the last three contractions - Start to start sits right under the number, because that is what they will ask you - One honest line about what your last hour actually looks like - And a summary you can read out the second you pick up the phone BUILT FOR THE NIGHT IT STARTS - One huge button. Tap to start, tap to stop. Nothing to learn at 3am - Dark by default, because that is when labor begins and the room is dark - A Live Activity on the Lock Screen and in the Dynamic Island - A home screen widget that starts timing before the app has even opened AN APPLE WATCH THAT KEEPS UP - Tap from your wrist while the phone stays on the nightstand - The session syncs both ways, live, with no waiting FOR YOUR PARTNER TOO - Anyone can pick up the phone and tap. There is nothing to hand over MORE THAN THE TIMER - Kick counter, saved session by session - A hospital bag list to tick off - Water broke, timed and noted - A clean summary to read out to a midwife, a nurse or a doctor - A keepsake card of the labor, for afterwards NO ADS. NOT ONE, NOT EVER No banners between contractions. No video before the timer will start. No pop up asking you to rate the app while you are in active labor. EVERYTHING STAYS YOURS No account, no sign up, no server. Your labor lives on your iPhone and in your own iCloud. Wavesong is not a medical device and does not provide medical advice. It shows you what your contractions are doing against the rule you were given. It does not diagnose and it does not decide. If you think you are in labor, call your provider. PRICING A one time purchase of $79.99 unlocks everything, on iPhone and Apple Watch, for this pregnancy and every one after it. A weekly plan at $12.99 is there if you only need the app for one night. There is no free trial. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings.
