Short answer
The UV index (0–11+) measures how intensely solar UV radiation reaches ground level. Children's skin has less protective melanin than adults' and sunburns faster, making UV a more significant factor for young children than for the adults they're with. The WHO and pediatric health organizations recommend that at UV 3+, children should have sunscreen and a hat; at 8+ they recommend actively limiting midday outdoor time. Lumi Weather factors UV into the Kid-Outing Score with an age-adjusted penalty — higher sensitivity for babies (0–2) — and the outfit checklist auto-populates: at UV 3+, a sun hat is added; at UV 6+, sunscreen and hat both appear; at UV 8+, sunglasses are added for children 3 and over (consistent with paediatric guidance that infant-specific eyewear has additional considerations). The app's Best Window algorithm favors early-morning and late-afternoon hours, which typically carry lower UV loads even on sunny days.

What to look for before choosing
- UV index scale: 0–2 = low, 3–5 = moderate (protection recommended for children), 6–7 = high, 8–10 = very high, 11+ = extreme
- Children burn faster than adults — SPF 30+ broad-spectrum sunscreen is recommended at UV index 3+ for children
- Peak UV hours are typically 10am–4pm; early morning and late afternoon carry meaningfully lower UV
- Cloud cover does NOT eliminate UV — an overcast sky can still deliver 70–80% of UV exposure
- Shade, UV-protective clothing, and a brimmed hat are more reliable than sunscreen alone for extended outdoor time
A practical decision process
- Define the job you need done most often.
- Test the app with real content or a realistic scenario.
- Check privacy labels and account requirements.
- Confirm export and backup options.
- Choose the pricing model you are comfortable maintaining.
Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
