Waverly

Time your contractions. Calmly, reliably. Waverly is a focused contraction timer for labor — 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 — 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 — 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 — no account, no servers, we never see it. • Partner updates — 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) — 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 — follow your provider. WAVERLY FULL (one-time purchase — 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 — 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.
