UV Index App

A useful UV Index app should do more than show one number. It should show current UV, hourly peaks, source freshness, skin-type context, SPF reminders, and clear caveats when live data is stale or suspicious.

What the app will track

TanPilot is designed as a weather utility plus tanning planner, with saved routines and timers in the mobile app.

Sample

High UV window

Avoid the peak if tanning. Use shade, broad-spectrum SPF, clothing, and a timer.

What to look for in a UV Index app

Look for hourly UV, clear risk bands, last-updated state, sunscreen reminders, and language that treats burn timing as an estimate. A bare UV number is helpful, but it is not the whole planning job.

  • Fresh data

    If UV reads 0 in daylight or the provider is stale, the app should explain that state rather than calculate from a bad number.

  • Actionable bands

    EPA and WHO bands should map into practical actions: shade, clothing, sunglasses, sunscreen, and shorter windows.

  • App handoff

    The mobile app is where alerts, saved places, Live Activity, and routine progress can keep working after the web visit.

UV bands TanPilot uses

These bands anchor the advice language across timing, SPF, and burn-risk pages.

UV Index Band TanPilot planning guidance
0-2 Low Usually lower risk for the average adult, with extra care still useful around reflection, altitude, or very sun-sensitive skin.
3-5 Moderate Protection starts to matter. WHO recommends sun protection when the UV Index is 3 or higher.
6-7 High Plan shorter exposure windows, avoid the daily peak, and use shade, clothing, sunglasses, and broad-spectrum sunscreen.
8-10 Very high Burn risk can rise quickly, especially near midday. Treat tanning time as a short, monitored exposure.
11+ Extreme Extra protection is needed. TanPilot should nudge toward shade-first planning rather than longer exposure.

Questions

Short answers for the exact search intent, without hiding the safety caveats.

Is TanPilot live in the App Store?

The App Store URL is not live yet. The website uses placeholders so the CTA can be wired as soon as the listing is available.

Will TanPilot expose a weather API key?

No. Live UV data is routed through a server-side proxy. The website can use a public proxy URL, but provider keys stay server-side.

Why not just use a weather app?

Weather apps often stop at the UV number. TanPilot connects UV to tanning windows, burn-risk estimates, skin type, SPF, and routines.
