How to build a pregnancy tracker app for iOS

What a pregnancy tracker app needs

• A due date and the current week, with a countdown
• A week-by-week update with a size comparison and what to expect
• A kick counter to log fetal movement
• A contraction timer for tracking frequency and duration
• A weight and symptom log over time
• An appointment list with reminders
• Checklists, for example a hospital bag or baby names
• Partner sharing so two people follow the same journey

The weekly journey and the countdown are the heart of the app. The tools matter, but the reason people open it every day is to see where they are in the timeline.

How to build it with AppFlight

Describe it in plain English, for example: "A pregnancy tracker where I set my due date and see my current week with a size comparison and what to expect. Add a kick counter, a contraction timer, a weight and symptom log, and an appointment list with reminders. Show a countdown to the due date, include a hospital bag checklist, and let my partner follow along with the same data." AppFlight plans the screens, generates native SwiftUI, and launches it in a live simulator so you can move through the weeks and use the timers immediately. For partner sharing, AppFlight can connect Supabase for accounts and live sync, with credentials kept server-side in your own Supabase. You iterate in plain language, for example adding a journal or photo timeline.

Monetization for a pregnancy tracker app

The dependable model is a free weekly tracker with a paid upgrade. Free users get the week, the countdown, and the basic tools; the subscription unlocks richer weekly content, partner sharing, full appointment and weight history, and checklists. Add a RevenueCat paywall to manage subscriptions, and use Superwall to test paywall designs without shipping an update. Because the journey is time-limited, a single well-priced plan that covers the whole pregnancy can convert better than a long subscription.

Shipping it to the App Store

When the app is ready, AppFlight signs the build, uploads to TestFlight so you can test the timers and weekly flow on your own device, then submits to the App Store with metadata and screenshots from the simulator. If Apple rejects the build, AppFlight reads the reason, works on the fix, and resubmits. Because this is health-adjacent and personal, include a real privacy policy, answer the privacy questions accurately, present the content as general information rather than medical advice, and tell users to consult their provider. Apple reviews every app, so a submission is not the same as an approval, but the whole pipeline runs without you opening Xcode.
