A UV app is a planning aid, not medical advice.
Bad or stale provider data should stop calculations instead of producing fake certainty.
Current UV does not replace sunscreen, shade, clothing, or eye protection.
UV-to-tan app
UV Index App
A useful UV Index app should turn one number into a plan. TanPilot shows current UV, hourly peaks, source freshness, skin type, SPF reminders, and stop cues for tanning sessions.
Get UV alerts, peak time, and SPF reminders.
Check UV today Live Current UV: With source freshness and suspicious-zero handling.
Peak time Hourly curve: The useful decision is when UV changes.
Skin + SPF Personal layer: Guidance changes by skin response and protection.

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.
0-2
Low
3-5
Moderate
6-7
High
8-10
Very high
11+
Extreme
- 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, with the cautions that keep the plan usable.
Is TanPilot live in the App Store?
Yes. TanPilot is live in App Store Connect with its App Store listing wired from the website CTA.
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.
