A pregnancy tracker that turns forty weeks into a calm, private journal. If you are a mom to be who wants every kick, contraction and bump photo kept on your own device rather than on a corporate server, Nest is built for you. It is a gentle companion from positive test to birth day, with no account, no sign-up and no cloud upload. Your prenatal notes stay on this phone, and the app works the same way on the plane, in the elevator and in the hospital wing with no signal. Useful whether this is your first 9 months, an IVF or high-risk pregnancy that needs careful notes for your OB, a second-time round where you already know what you want to track, or a quiet space to share weekly memories with a partner. Every feature described below is unlocked only with an auto-renewable subscription purchased inside the app. New users receive a 3 day free trial; you may cancel anytime during the trial to avoid being charged. Open the app and the week-by-week timeline shows fetal development, body changes and daily tips across all forty weeks of prenatal care. The ACOG-aligned kick counter logs fetal kicks with the ten-in-two-hours method, the contraction timer captures frequency, duration and intensity at a tap, and weight, blood pressure and symptom tracking sit beside an appointment scheduler with doctor notes. A photo card per week becomes your baby diary, and the third-trimester checklist keeps hospital bag and birth plan ready. A weight gain chart sits beside the bump photos so you can see the curve and bring it to your next visit instead of squinting at three apps. Beyond the basics, Nest handles the parts of pregnancy that other trackers ignore. Mood and energy entries ride beside the medical numbers without judgement, food aversions and cravings log in two taps, and a kick-and-contraction history view lets you spot patterns over days, not just minutes. If labour starts at 3 in the morning, the timer is one tap from the Lock Screen, and the contraction list exports to a tidy summary you can read aloud to the triage nurse. Twin pregnancies get parallel tracks, and miscarriage and loss entries are handled with quiet care rather than a confetti screen. The interface ships in 15 languages with full VoiceOver and Dynamic Type, smart reminders nudge you before appointments and milestones, and a discreet mode hides sensitive content on a shared device. Baby growth, contractions and kicks stay on your phone unless you choose to sync with Apple Health. There is no account, no cloud, no third-party server in the loop โ€” the data is yours and it stops at the edge of your device. Unlock with Pro: - Live Activities for kicks and contractions on the Lock Screen - Home Screen and Lock Screen widgets so your week is always glanceable - Apple Watch app for kick counting and contraction timing from your wrist - PDF health report for your doctor and Apple Health two-way sync - Unlimited photo memories, birth-prep notes, premium icons and themes Subscription Pricing & Terms Features require a subscription.

Read full description

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. SUBSCRIPTION Bumpy Premium is available as a weekly subscription with a 3-day free trial, an annual subscription, or a one-time lifetime unlock. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period.
