| Hi HN,
I built Corgina, an open-source pregnancy health tracker for my wife after getting frustrated with commercial pregnancy apps that sell user data and lack privacy.
GitHub: https://github.com/benjaminshafii/Corgina KEY FEATURES:
• Voice-first AI logging: "I ate tahini for lunch" → automatically logs at 12pm with full nutritional data (calories, protein, carbs, fat)
• 100% private: All data stored locally on device, never touches the cloud
• Your own API key: Bring your own OpenAI API key for AI features (GPT-4o for nutrition estimation)
• Tracks food, water, vitamins, symptoms, and PUQE scores (pregnancy nausea severity)
• iOS 26 Liquid Glass UI with on-device speech recognition TECHNICAL DETAILS:
- SwiftUI with iOS 26 design patterns
- On-device speech recognition (Speech framework)
- GPT-4o for nutrition estimation (~$0.10-0.30/day usage)
- Actor-based concurrency for background processing
- 100% local storage (UserDefaults + file system)
WHY I BUILT THIS: Most pregnancy apps treat your health data as a product to sell. My wife needed something that:
1. Respects privacy (no cloud storage, no analytics, no tracking)
2. Makes logging effortless (voice commands instead of endless forms)
3. Provides accurate nutrition data for pregnancy diet tracking CURRENT STATUS:
- iOS 26 only at the moment (requires iPhone with iOS 26.0+)
- Install via Xcode (sideload) - full instructions in repo
- Setting up TestFlight for easy testing - will share link in comments soon!
- Free to use and modify
I'd love feedback from the HN community, especially:
- Privacy-conscious parents
- iOS developers interested in iOS 26 patterns
- Anyone with experience building health tracking apps If there's interest, I'm happy to set up a TestFlight beta for easier installation. Just let me know in the comments!
Happy to answer any questions! |
