Overview
Hera is a minimalist iOS app designed to capture rambling voice notes, transcribe them with OpenAI, and convert them into structured documents with calendar and reminders integration. It records with AVFoundation, stores high-quality audio in per-recording folders, and provides visual feedback during recording. The app uses a native iOS stack (Swift, SwiftUI) with SwiftData for local persistence and follows an MVVM modular architecture. Key components include DisplayableRecording, AudioManager, OpenAIService, CalendarManager, with each recording stored as a folder containing audio.m4a, transcription.txt, and analysis.json. The UI is calm and minimalist, featuring a cat mascot, dark/light mode, and support for Markdown import/export. Data remains local with API keys stored in the keychain. To run, clone the repo, open Hera.xcodeproj, configure the OpenAI API key, and build. Future wishlist items include iCloud sync, PDF export, richer sharing, cost display after analysis, and an animated mood tracker; publishing to the App Store requires an Apple Developer Program membership.
