Heliophilia: Daylight Tracker - Track daylight, UV & sunrise. Close the day with gratitude.

by•
Heliophilia shows you how much daylight you have today, how it compares to yesterday, and where you are in the year's cycle. Sunrise, sunset, UV Index, and a visual graph of the whole year for your exact location. At the end of the day, write one thing you're grateful for. A quiet ritual to close the day with intention. No account. No subscription. No data collected. Pay once, keep it forever. Built by a solo designer in the Netherlands with AI assistance, from idea to App Store in weeks.

Hey Product Hunt! I'm Yannis, a product designer from the Netherlands and this is my first solo app. Heliophilia started as a personal project to test AI-assisted development with Cursor. What surprised me was how fast things moved. From zero Swift experience to App Store in a matter of weeks. The app itself is something I genuinely wanted to exist. I live in the Netherlands where the difference between a December day and a June day is dramatic, and I wanted something that made that visible in a beautiful way. The gratitude side came naturally, noticing the light and reflecting on the day felt like they belonged together. It's a small, focused app. No ads, no subscription, no data collected. Just a clean daily ritual for people who love sunlight. Would love to hear what you think, and happy to answer any questions about the build process, the design, or what's coming next. :)
