Bumpy is a calm, clutter-free pregnancy companion built around the one tool you will reach for most: a clean, reliable contraction timer. No ads getting in the way, no account to create, and everything you track stays private on your iPhone. THE CONTRACTION TIMER IS ALWAYS FREE When things get real, you should not be fighting a paywall. Bumpy's contraction timer is free, forever. Tap once when a contraction starts and again when it ends. Bumpy logs the length and the interval, shows your averages over the last hour, and gently surfaces when your pattern resembles the widely-shared 5-1-1 guideline, as general information. ALSO FREE - Kick counter with a simple count-to-ten session and history - Due-date countdown with your current week and progress CYCLE & FERTILITY MODE, FROM CYCLE TO BUMP Not pregnant yet? Choose "Tracking my cycle" and Bumpy becomes a private period tracker. Log your period start and end and your flow, and see your predicted next period, fertile window and estimated ovulation day on a clean monthly calendar. Add symptoms, mood and notes for any day. Predictions use the average of your own logged cycle lengths (28 days until you have logged two cycles), with ovulation estimated 14 days before your next period, and the app explains how each estimate is made, with links to public health sources. When you become pregnant, switch modes in Settings and Bumpy can suggest a due date 280 days after your last period start. Period logging and the calendar are free. PREMIUM ADDS THE FULL COMPANION - Weekly guide: your baby's size and development, week by week - Hospital bag checklist you can tick off - 260+ baby names with meanings and origins, plus favorites - Appointment log for checkups and scans - Weight log with your trend at a glance - Cycle insights: cycle-length history, period history and symptom patterns PRIVATE BY DESIGN No account. No ads. No tracking. Everything you enter is stored only on your device. We never see it and we never sell your data. GENERAL INFORMATION, NOT MEDICAL ADVICE Bumpy provides general information only and is not medical advice. Every pregnancy is different. Always contact your doctor or midwife with questions about labor, your health, or your baby. FREE AND PREMIUM The contraction timer, kick counter, due-date countdown, period logging and the cycle calendar are free with no limits. Premium unlocks the weekly guide, hospital bag checklist, baby names, the appointment and weight logs, and cycle insights.
