SPECTRA / Weather - Minimal weather app with real-time atmospheric art

SPECTRA strips away the visual noise of conventional weather apps and renders atmospheric conditions as real-time generative art. Six dynamic modes: beam (clear), precipitation lines (rain), noise field (clouds), lightning (storms), vortex (wind), particles (snow). Each visualization responds to live weather data—intensity, density, motion. The clear-sky beam tracks actual solar position, widening at noon and narrowing at dusk. No icons. No charts. Just atmospheric presence.

Hey Product Hunt 👋 I'm Kaz, and I just launched SPECTRA after months of obsessing over a single question: what if weather forecasts were rendered as light and motion instead of icons and numbers? What it does: SPECTRA translates atmospheric conditions into real-time generative visualizations. Rain becomes falling lines. Wind becomes turbulent vortex patterns. Clear skies become a solar-responsive beam that widens at noon and narrows at dusk. Why I built it: I got tired of weather apps that feel like spreadsheets. I wanted something you could glance at and immediately feel the conditions—not analyze them. Something that reflects the atmosphere outside without demanding attention. Technical highlights: - 19-beam solar irradiance simulation (tracks actual sun elevation) - Real-time parameter mapping: rain intensity, wind speed, cloud cover all drive the visuals - Built in SwiftUI with 60fps Canvas rendering - Localized in 8 languages The model: 7-day free trial, then $5.99 one-time unlock (no subscription, no ads, no tracking) What I'd love feedback on: - Does the generative approach resonate with you? - Which weather mode is your favorite? - Any features you'd want to see in v1.1? Thanks for checking it out. This community has been incredibly supportive of indie makers, and I'm excited to hear what you think. [App Store link]
