About

Nest

Read full description

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.
