A UV tracker is a planning aid, not medical advice.
High UV can happen on cool or cloudy days.
Use protection from UV 3 upward and never treat low numbers as risk-free for everyone.

UV Tracker
A UV tracker should show current UV, the hourly peak, source freshness, and whether the number is safe to use. TanPilot connects that tracker to SPF reminders, skin type, tanning windows, and burn-risk estimates.
Current UV Core: Freshness matters as much as the number.
Hourly peak Planning: The peak decides shade-first windows.
Alerts App handoff: Saved places and push reminders need the app.

What makes a UV tracker useful
The tracker should show the current UV number, the hourly curve, the likely peak, and whether data is stale or suspicious. Then it should translate those states into outdoor planning language.
-
Freshness state
If data is stale or daylight UV looks wrong, TanPilot should stop calculations rather than guessing.
-
Saved places
A useful app tracks home, beach, vacation, and travel locations without forcing a fresh search each time.
-
Actionable alerts
Alerts should say when UV crosses a threshold, when the tanning window opens, and when SPF needs attention.
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, without hiding the safety caveats.
What is the difference between UV tracker and UV Index app?
A UV Index app may show the number. A tracker adds hourly changes, saved places, alerts, and context for SPF or tanning decisions.
Can UV be high when it is cloudy?
Yes. Clouds can reduce UV, but UV can still remain high. The tracker should use UV directly rather than comfort or temperature.
Will TanPilot save UV alerts?
That is the planned app handoff. The website gives the answer; the app should store alerts and saved places.
