## Description

Helios UV is a beautiful, no-nonsense UV-index tracker for every Apple device
  you own. Live forecasts, burn-time predictions tailored to your skin type,
  threshold alerts, and widgets that follow the sun across your day.

  WHAT HELIOS DOES

  • Live UV index — updated hourly from Apple WeatherKit, with 30-second
  interpolation between samples so the displayed value tracks reality, not the
  last forecast tick.

  • Time to burn — personalized to your Fitzpatrick skin type (I–VI), the same
  six-type scale widely used in dermatology and public-health sun-safety
  guidance. Helios maps your skin type to a documented minimum erythemal dose
  and recomputes minutes-to-burn every 30 seconds against the current UV.

  • Trend you can read — a 24-hour forecast rendered as a Catmull-Rom-spline
  sparkline, segments colored by UV intensity. See the peak coming, and the
  safe-time crossings flagged.

  • Threshold alerts — pick the UV level that matters to you and Helios fires a
  local notification when the forecast crosses it (Pro). Dangerous-UV safety
  alerts are free for everyone.

  • Widgets — Home Screen, Lock Screen, watch face, Smart Stack, macOS desktop,
  Apple TV dashboard. Pro unlocks every surface.

  • 12 Pro color palettes — Mono, Mono Teal, Vegas Neon, Pastel, Response, and
  more. Standard and a colorblind-friendly High Contrast palette are included
  free.

  EVERYWHERE YOU WEAR, CARRY, OR SIT

  One purchase. Five platforms. Each surface drawn for the device it lives on:

  • iPhone & iPad — full dashboard, two widget sizes, threshold-crossing
  notifications
  • Mac — menu bar status item, dashboard window, four widget sizes
  • Apple Watch — four complications and a Smart Stack tile
  • Apple TV — a leanback living-room dashboard

  POWERED BY APPLE WEATHERKIT

  Every UV reading in Helios comes from Apple's own forecasting pipeline — the
  same data that powers Apple's built-in Weather app. No scraped feeds, no
  third-party API in front of someone else's API.

  PRIVACY

  Helios has no analytics SDKs, no advertising, no third-party crash reporters,
  and no Kludge-operated server. Location goes to Apple WeatherKit;
  subscriptions go to Apple StoreKit; settings stay on your device. Full privacy

  The minutes-to-burn estimate is a guide, not medical advice. Wear sunscreen,
  reapply, and consult a dermatologist about your personal sun safety.
