Solaris
Know the best time to go outside — personalized for you.
Most weather apps tell you what's outside. Solaris tells you what it means for your body. Get a daily outdoor health score based on UV, pollen, air quality and wind — weighted against your skin type, allergies and goals. Track vitamin D in real time, get pollen alerts for your specific triggers, and receive an AI morning briefing written personally for you. Free to download. 7-day Premium trial included.
Hey Product Hunt 👋 I'm Sai, the solo developer behind Solaris. I built this because of a frustrating personal experience — I have Type IV skin and I was using a standard UV app that kept telling me UV was "high" without any context for what that actually meant for my skin specifically. After some digging into dermatology research on the Fitzpatrick scale I realized that what's a dangerous UV level for someone with Type I skin is completely safe for me, and no app accounted for that. That led me down a rabbit hole. If UV safety is personalized, why isn't everything else about going outside personalized? Air quality affects people with asthma differently. Pollen affects people based on their specific triggers. Vitamin D production depends on your skin pigmentation. Wind matters more to cyclists than walkers. Every outdoor recommendation should be built around the person, not just the conditions. So I built Solaris. It took about 8 months of evenings and weekends. The feature I'm most proud of is the AI Daily Briefing — every morning you get a 2 to 3 sentence personalized summary of what today means for your specific body outdoors. Something like "Good morning — UV is safe for your skin until 10am, pollen is low, and conditions are ideal for your run. Go before noon for the best vitamin D window." It sounds small but it's the thing that makes the app feel like it actually knows you. The hardest technical challenge was the vitamin D tracker. Calculating real-time IU estimates from your skin type, the current UV index, which body parts are exposed, and cloud cover required going deep into dermatology literature. I'm still not sure any consumer app has done this before. I'm launching today to get real feedback. The questions I most want answered: 1. Does the personalization angle resonate or does it feel overwhelming to set up? 2. Is the Daily Outdoor Health Score concept clear enough or does it need more explanation? 3. For anyone who deals with skin sensitivity, allergies, or vitamin D concerns — does this solve a real problem for you? Happy to answer any questions about the tech stack, the design decisions, or the science behind any of the features. And if you try it and find anything broken or confusing please tell me directly — I read every single piece of feedback. Thank you for the upvotes and for trying Solaris 🌿
