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!
