Waverly
Read full descriptionHide full description
Time your contractions. Calmly, reliably. Waverly is a focused contraction timer for labor ā one big button, clear numbers, and a calm screen for one of the most intense moments of your life. Not a pregnancy super-app. Just contractions, timed right. WHY WAVERLY We read the reviews of every popular contraction timer. People love that these apps exist ā and rage at what they do during labor: ads popping up mid-contraction, a paywall after a handful of contractions, losing the whole session when the app gets swiped away, or being asked to "rate us" while in labor. We built Waverly to do the opposite. ⢠We never lose your session. Every tap is saved the instant you make it. Swipe the app away by accident? Your labor is exactly where you left it. ⢠Timing is always free. Unlimited contractions and the 5-1-1 pattern alert ā free, forever. No "6 contractions then pay." ⢠No ads. Ever. Not during a contraction. Not anywhere. ⢠Built for labor. One giant button you can hit without looking, huge readable numbers, a true-black night screen that stays awake, and a Lock Screen Live Activity so you don't drain your battery keeping the app open. ⢠Your data is yours. Stored on your phone and your private iCloud ā no account, no servers, we never see it. ⢠Partner updates ā send your birth partner a quick update THE 5-1-1 PATTERN, DONE RIGHT Waverly shows when your contractions reach the 5-1-1 guideline many providers reference (about 5 minutes apart, ~1 minute long, for an hour) ā and lets you set your own threshold (4-1-1, 3-1-1, or custom) if your provider gave you a different one. It's clear, sourced, and always reminds you: every labor is different ā follow your provider. WAVERLY FULL (one-time purchase ā no subscription) ⢠Export a clean PDF/summary to share with your provider ⢠Your full history archive across sessions Timing, the 5-1-1 alert, and backup are always free. Full just adds the extras ā once, no subscription. WHAT WAVERLY IS NOT Not a week-by-week pregnancy tracker, not a baby app, not a medical device. It does one thing extremely well. IMPORTANT Waverly is an informational timing tool, not medical advice, and not a medical device. Always follow your healthcare provider's instructions.

Contraction Timer
Read full descriptionHide full description
Waves is a calm, one-tap contraction timer and labor tracker. Tap once when a contraction starts, tap again when it stops. Waves does the rest - duration, the interval since the last one, your rolling hourly averages, and a plain-English read on which stage of labor the pattern looks like. WHEN YOU'RE IN IT, ONE TAP IS ALL YOU HAVE Start and stop with a single tap on a target big enough to hit without looking at the screen. No menus, no forms, no setup while you're breathing through a contraction. Lock Screen controls let you start and stop timing without unlocking your phone. KNOW WHICH STAGE YOU'RE IN Most timers hand you a table of numbers and leave you to work out what it means at 3am. Waves reads the pattern for you and tells you where you are: practice contractions, early labor, active labor, or time to go. It watches for the well-known 5-1-1 rule - five minutes apart, lasting one minute, holding steady for one hour - and surfaces it the moment your log matches. BRAXTON HICKS OR THE REAL THING? Short, irregular contractions are usually Braxton Hicks - practice, nothing to worry about. Rather than making you label each one, Waves looks at the whole pattern and tells you whether it currently looks like practice or real labor. SEE THE TREND, NOT JUST THE MOMENT Pattern Insights breaks the last six hours into hourly windows, so you can see at a glance whether things are picking up, holding steady, or easing off. Waves also estimates when the current pattern began - useful information for your midwife or doctor when you call. FEATURES ⢠One-tap contraction timer - a big target you can hit without looking ⢠Automatic duration, interval and rolling hourly averages ⢠Labor stage tracker: practice, early labor, active labor, time to go ⢠5-1-1 rule detection ⢠Braxton Hicks vs real labor pattern read ⢠Pattern Insights: a six-hour trend in hourly windows ⢠Estimated labor start time ⢠Due date with a gentle heads-up if a real pattern shows up unusually early ⢠Optional intensity slider to rate each one as it happens ⢠Optional paced breathing animation to breathe along with ⢠Auto-stop, in case you forget to end a contraction (1ā15 minutes, your choice) ⢠Full history you can edit - fix a time, add one you missed, delete a mistake ⢠Lock Screen controls, where Live Activities are supported ⢠Follows your system dark mode ⢠Works completely offline FOR THE PERSON HOLDING THE PHONE Plenty of contraction tracking happens on a partner's phone while the person in labor breathes. Waves is built for that too - big targets, high contrast, calm colors, no reading required. FREE, PRIVATE, NO ACCOUNT Waves is free. No ads, no account, no sign-up, no subscription. Your history is stored on your own device and never uploaded anywhere. If the app helps you, there's an optional tip jar inside - entirely up to you, and every feature works without it. IMPORTANT Waves is a timing and organizing tool, not a medical device. It does not diagnose labor and is not a substitute for advice from your doctor or midwife. Every pregnancy is different - always follow your provider's specific guidance, and call them if anything feels wrong, even before the 5-1-1 pattern is reached.
