v1.0.0 — Initial Open Source Release

CycleWeather is now open source under the MIT License.

Built as an experiment in agentic AI-assisted iOS development — no prior Swift, Xcode, or GitHub experience — and shipped to the App Store in four days using Claude Code.

What's here:

• SwiftUI cycling weather app for iOS 17.0+
• WeatherKit integration (primary weather data, no API key required)
• Open-Meteo AQI and solar radiation data (no API key required)
• Cycling-specific tactical weather alert engine with three tiers
• Solar Heat Gain Index (SHGI) calculated from direct/diffuse radiation
• NOAA/NWS precipitation radar overlay via Iowa Environmental Mesonet (no API key)
• Saved locations carousel (up to 10 locations)
• Minute-by-minute precipitation forecast pane
• URL scheme-based alternate icon unlock system
