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.

Verdict
The clearest difference is ratings volume: UV Watch at 6 against Helios UV's 1. UV Watch also leads on iOS requirement (14.0.0 vs 17.0). Helios UV's advantage is device support (5 vs 3). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. UV Watch sells 2 in-app purchases, starting at $0.99 per month and Helios UV sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for UV Watch against 5.0 for Helios UV. That said, the two scores are not equally well evidenced: UV Watch has 6 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
