Sun Day is an open-source Android application designed to help you stay informed about the UV Index and optimize your Vitamin D production, all while minimizing sun exposure risks. Inspired by its iOS counterpart, Sun Day provides real-time UV data, personalized Vitamin D calculations, and adapts its interface dynamically to the time of day.
This project is being vibecoded via Goose, mainly with Gemini 2.5 Pro.
This is the first Android app I've ever created so expect issues! Learning on the fly here :)
- Real-time UV Index: Get the current UV Index for your location.
- Personalized Vitamin D Calculation: Understand your estimated Vitamin D production based on UV, skin type, clothing, and sunscreen.
- Dynamic Background: The app's visual theme changes throughout the day to reflect current light conditions.
- Edge-to-Edge UI: A modern, immersive user interface that fully utilizes your device's screen.
