Every Tool You Need for Sun Safety
SunUp isn't just a UV meter. It's a complete personal sun protection system with 10 integrated features built around your unique needs.
UV Monitoring & Forecasting
SunUp delivers real-time UV Index readings for your exact GPS location, updated every 15 minutes from professional weather services. See the current risk level, today's hourly UV curve, peak UV time, and a full 48-hour forecast — so you can plan your week of outdoor activities in advance.
What's included:
- Real-time UV Index, updated every 15 minutes
- 48-hour hourly UV forecast
- Peak UV alert (when UV will be strongest)
- Color-coded WHO risk scale (Low/Moderate/High/Very High/Extreme)
- Altitude-adjusted calculations (4% increase per 1,000 ft)
- Surface reflection factors (snow, sand, water, concrete)
- Cloud cover adjustment — accounts for 80% UV penetration
Personalization Engine
SunUp is the only UV app built on the Fitzpatrick Skin Classification System — the medically validated method for measuring skin's UV sensitivity. Input your skin type (I-VI), age range, and gender, and SunUp calculates your unique safe exposure window. A Type I person and a Type IV person face radically different risks at the same UV level — SunUp knows the difference.
What's included:
- Fitzpatrick skin types I through VI (all classifications supported)
- Type I: Always burns, never tans — Celtic, very fair
- Type II: Usually burns, tans minimally — Fair, Northern European
- Type III: Sometimes burns, tans gradually — Medium skin
- Type IV: Burns minimally, tans easily — Olive, Mediterranean
- Type V: Rarely burns, tans deeply — Brown, Middle Eastern
- Type VI: Never burns, deeply pigmented — Dark brown/Black
- Age-adjusted UV sensitivity (children, adults, seniors)
- Gender-specific activity recommendations
Activity Planning (12+ Activities)
Different activities expose you to different amounts of UV radiation. A swimmer faces reflected UV from water. A skier faces reflected UV from snow (85% reflectivity). A cyclist is moving through changing UV conditions. SunUp accounts for these differences and delivers activity-specific safe exposure times, SPF recommendations, and protective gear checklists.
What's included:
- Hiking and trail running (altitude + terrain factors)
- Beach and swimming (water reflection + surface exposure)
- Cycling and mountain biking (speed, exposure duration)
- Gardening and yard work (face/arm exposure patterns)
- Skiing and snowboarding (85% snow reflection)
- Fishing and boating (water reflection + prolonged exposure)
- Golf (midday exposure during peak UV)
- Running and jogging (outdoor exercise planning)
- Children's outdoor play (school recess, sports)
- Camping (multi-day UV exposure management)
- Outdoor events and festivals
- Construction and outdoor work
Air Quality Intelligence
SunUp is the only UV safety app that also monitors Air Quality Index (AQI) — because outdoor safety isn't just about UV. Poor air quality from wildfire smoke, pollution, or allergens changes whether you should go outside at all. SunUp combines UV and AQI data into a single go/no-go outdoor recommendation.
What's included:
- Real-time AQI (Air Quality Index) readings
- AQI scale: Good (0-50), Moderate (51-100), Unhealthy (101-150), Very Unhealthy (151+)
- PM2.5 and PM10 particle monitoring
- Wildfire smoke detection and alerts
- Combined UV + AQI outdoor safety recommendation
- Special warnings for children, elderly, and respiratory conditions
- 5-day AQI forecast alongside UV forecast
- Geographic AQI heatmap (select locations)
Family & Multi-Profile Mode
Create separate profiles for every family member — children, teenagers, elderly parents, or friends with different skin types. Each profile stores their skin type, age, and activity preferences. Plan a single outing and instantly see personalized recommendations for each person. You can even check UV conditions for remote locations — perfect for monitoring grandparents in Florida or kids at summer camp.
What's included:
- Unlimited family member profiles
- Individual skin type (Fitzpatrick I-VI) per profile
- Age-specific recommendations (child, teen, adult, senior)
- Remote location monitoring (check UV anywhere in the world)
- Side-by-side comparison of family member safe times
- Group activity planning for outdoor family events
- Pediatric skin sensitivity adjustments
- Senior skin protection guidance (thinning skin, medications)

SunUp's 230+ personalized smart tips are contextual — they change based on your current UV level, activity, skin type, and time of day. Not generic sun safety advice you've heard a thousand times — specific, actionable guidance matched to your exact situation right now.
