HelioCast – UV & Weather

Hyperlocal UV index, air quality, and weather in a beautiful one-click popup.

HelioCast – UV & Weather is a sleek, privacy-first Chrome extension that brings hyperlocal weather, UV index, and air quality data to your browser toolbar—instantly and beautifully. With just one click, you get a clean, modern popup showing everything you need to know before stepping outside: current temperature (and “feels like”), real-time UV risk level (from Low to Extreme), and US Air Quality Index (AQI) with clear health guidance. Whether you’re heading out for a run, walking the dog, commuting, or planning weekend plans, HelioCast helps you make smarter, safer decisions—without opening another tab or app. Unlike bloated weather apps, HelioCast focuses only on what matters: actionable, location-specific insights updated in real time. The extension features a scrollable hour-by-hour forecast showing both temperature and UV intensity, plus a compact 5-day outlook with daily highs, lows, and peak UV levels. Its elegant glassmorphism-inspired interface adapts seamlessly to dark or light mode, and everything loads in under a second. You control your experience: choose to display temperature or UV index right in your toolbar badge, switch between Celsius and Fahrenheit, toggle 12- or 24-hour time, and set your preferred theme—all from a simple settings page. HelioCast works with or without location access: if you prefer, just search any city or ZIP code manually. Built on trusted, open global datasets from Open-Meteo, HelioCast requires no account, shows no ads, and collects no personal data. It doesn’t track your browsing, sell your info, or bombard you with notifications. Location coordinates are used only to fetch forecasts and are never stored on external servers. Everything—from your settings to your last searched location—stays safely on your device. Install HelioCast if you want fast, beautiful, and responsible weather intelligence that respects your time, your eyes, and your privacy. One click. Total clarity. Every day.
