Hi Product Hunt! I'm the maker of OpenWindow. This project started in a doctor's clinic. After moving to Melbourne, extreme heat left my partner dizzy and nauseous. Our GP’s verdict: heat stress. I realized "fresh air" isn't always healthy: humidity, PM2.5, and extreme temps can turn a home into a hazard. I built OpenWindow to provide an instant YES/NO verdict on whether it’s safe to open your windows, using real-time EPA data. Key Features: Invisible Threat Tracking: Monitoring AQI/PM2.5. Mold Prevention: Flagging high-humidity risks. Heat Stress Logic: Protecting your indoor "sanctuary." Independent & Private: No ads, no tracking, built while job hunting to help other families. I’d love your feedback on the logic and features. Is it safe to open your windows today? Try it out and let me know!
