Contraction Timer

Time contractions with one tap โ€” and know when it may really be time to go. TWO TAPS, NOTHING ELSE Tap the big circle when a contraction begins, tap again when it eases. Durations, intervals and your hourly pattern are worked out for you โ€” no forms, no clutter, designed for one hand in the middle of the night. THE 5-1-1 RULE, WATCHED FOR YOU The guideline midwives give for heading to the hospital: contractions about every 5 minutes, lasting about 1 minute, for about 1 hour. The app quietly watches your pattern and tells you when it matches โ€” with a notification even if your phone is locked. Prefer the stricter 4-1-1 rule? One switch in Settings. KEEPS GOING ON THE LOCK SCREEN A Live Activity shows the running contraction on the Lock Screen and in the Dynamic Island โ€” you can end it right there, without unlocking. BUILT FOR REAL LABOR โ€ข A big, calm timing button you can't miss โ€ข "Since last contraction" always in view โ€ข Edit or discard any contraction afterwards โ€ข Practice runs (Braxton Hicks) โ€” time them, mark them, keep them separate โ€ข Sessions wrap up gently when things go quiet SHARE WITH YOUR MIDWIFE OR DOCTOR Send a session summary as text the moment it ends, or export CSV. Pro adds a clean, printable PDF report for your care team. YOUR DATA STAYS YOURS Everything is stored on your iPhone only. No account, no ads, no tracking โ€” nothing ever leaves your device. PRO One simple upgrade โ€” as a one-time purchase or a yearly subscription โ€” unlocks your full history, the PDF report and pattern insights. Timing, the 5-1-1 alert and text sharing are free forever. Contraction Timer records the times you enter by hand. It is not a medical device โ€” always follow the advice of your midwife, doctor or hospital.

The calm, honest labor toolkit โ€” built to be used half-asleep, one-handed, at 3am. ONE-TAP CONTRACTION TIMER Tap when a wave starts, tap when it ends. Duration and time-between are logged automatically. Started the timer late? Fell asleep mid-contraction? Edit or delete any entry โ€” included, forever. YOUR PATTERN, IN PLAIN LANGUAGE "Last hour: every 6 min, lasting ~55s." Waves compares your last hour to the classic 5-1-1 rule with a threshold you agree with your midwife. Information, never commands โ€” the decision stays with you and your care team. KICK COUNTS FROM WEEK 28 Count to 10 movements daily, keep the streak, get a gentle reminder. The quiet habit your midwife will ask about. BUILT FOR THE PARTNER TOO During labor the phone is often in the partner's hands: giant tap targets, neutral wording, and a one-tap export of the whole log for the midwife. NO ADS. EVER. No weekly subscription. No account. Your contractions, kick counts and due date never leave your device. An optional one-time purchase adds calm extras: the hospital-bag checklist, a guided breathing pacer and the partner's guide. Waves provides information, not medical advice. Always follow the guidance of your midwife or doctor. Privacy Policy: https://laborkit-web.web.app/privacy/ Terms of Use: https://laborkit-web.web.app/terms/
