Contraction Timing, The Birthsmarter Way Created by a birth educator + an Apple Design Award-winning developer. Take the guesswork out of labor with a contraction timer designed to be calming, intuitive, and actually helpful. WHAT MAKES THE BIRTHSMARTER CONTRACTION TIMER DIFFERENT? This isn't just another contraction app—it's a labor support tool rooted in real childbirth education and designed to reduce stress, not add to it. WHAT YOU GET: -A smart, easy-to-use interface for confidence and peace of mind -Visual breathing cues to support rhythmic breathing (Hypnobirthing-friendly) -A detailed contraction log with last-hour averages -The option to hide the clock/timer to minimize distractions -Share your average contraction pattern via text or email to a partner or provider EASY TO USE: -Touch-anywhere start/stop means no fumbling for buttons -Timer continues even if you close the app—take photos, change music, or call your doctor worry-free SMART TIMER: -Edit contraction entries manually if needed -App auto-deletes contractions under 15 seconds or over 2.5 minutes to filter accidental taps or missed stops A GENTLE WARNING: Even though this app is beautifully designed and soothing to use, we do not recommend timing all of your contractions. Best practice: Track contractions for 45–60 minutes to identify a pattern, then stop. Check again when something changes. THE SCIENCE: The uterus is a powerful muscle that contracts to push your baby down and help open the cervix. These contractions are fueled by oxytocin—the hormone tied to love, trust, and connection. To support oxytocin production and efficient labor, we've built this app to minimize distractions and help you stay in the zone. We can't promise this app will shorten your labor—but physiologically speaking, it might help. WHAT YOU DON'T GET: -Big red boxes or alarming countdowns -Condescending colors, graphics, or music -Generic, one-size-fits-all advice -Confusing graphs, ads, or unnecessary icons -During labor, your job is to cope with contractions—not to analyze data. While bells and whistles are great in video games, the Birthsmarter Contraction Timer is designed to support your experience with thoughtful, subtle features that make a difference. Note: This app is not a replacement for medical care or advice. Always consult your medical team and use the data you collect here as a tool for shared decision-making.
