Pregmate-Style TTC Community App

I need a complete reproduction of the Pregmate mobile experience, re-branded for a “trying-to-conceive” community. Please download and explore their app before responding; my expectation is that every flow you see there will be mirrored here.

The build must launch on both iOS and Android from a single codebase. Core functions include accurate ovulation tracking tied to a period and pregnancy calendar, a real-time community forum, and an in-app library of educational articles, videos, and tips. Users should be able to sign up with email/password or jump straight in through their preferred social account, then sync data seamlessly across devices.

I will look for:
• Pixel-level parity with Pregmate’s tracker, calendar views, reminders, charts, and symptom logging
• A forum that supports threads, replies, @mentions, image upload, and basic moderation tools
• A CMS or simple admin panel so I can publish new educational resources without additional development work

Feel free to employ Flutter, React Native, or another cross-platform framework as long as performance is smooth and native-feeling. Hand-off should include all source code, documented API endpoints, build instructions, and a short video demo showing the core journey from onboarding through posting in the forum.

Let me know your preferred tech stack, estimated timeline, and any similar apps you have shipped.
