SPF Tan Timer & Sunburn Alerts
Only for iPhone
Free · In‑App Purchases
iPhone
Your skin type + today's UV = your safe time outside, in minutes. Tan without burning, track vitamin D, and keep a photo history of your skin.
Know exactly how long you can stay in the sun today — for your skin, in your city, right now.
Solaria is your personal sun coach. Tell it your skin type once, and it turns the live UV index into a number you can act on: your safe time outside, in minutes. Whether you want to build a real tan or simply stop burning, Solaria tells you when to go out, when to cover up, and when you've had enough.
TWO MODES, ONE APP
• Tan — a day-by-day plan that builds colour in short, measured blocks, sized to today's UV
• Protect — your personal daily UV budget, with a warning before you reach it
KNOW YOUR LIMIT
Your safe time is calculated from your skin type, the live UV index for your exact location, the SPF you're wearing, how much skin is uncovered, altitude, and reflective surfaces like water, sand and snow. Start a session and a live ring counts your dose as it happens — on screen, on the Lock Screen and in the Dynamic Island. Stepped into the shade? One tap, and the maths follows you.
TRACK WHAT THE SUN DOES TO YOUR SKIN
• Skin zones — photo timelines for face, neck, hands, forearms and legs
• Aligned camera — a ghost of your previous photo helps you frame the exact same shot
• Comparisons — put any two dates side by side and see the difference
• Moles — catalogue them by body area, keep a photo history, and run a guided ABCDE self-check
• Re-check reminders — a nudge three months after the last mole photo
EVERY DAY, NOT JUST BEACH DAYS
• Live UV index and hourly forecast for your location
• Vitamin D — how many IU you actually made in the sun today
• Journal — dose, time outside and vitamin D, by day and by week
• Recovery plan — a step-by-step routine for when you overdo it
• Sun Passport — your skin type, your streak and your achievements
• Home Screen widget, Live Activities and Dynamic Island
• Smart alerts — high UV, daily limit reached, morning forecast, safe hours, evening skin check
Available in English, German, Spanish, French, Italian, Polish, Portuguese, Russian and Ukrainian.
HONEST BY DESIGN
No dark patterns, no countdown tricks, no buried buttons. Solaria Pro is a subscription that supports development, and you can cancel any time from Settings — the app will walk you through it.
Solaria offers general wellness guidance and estimates only. It is not a medical device, it cannot diagnose anything, and it is not a substitute for professional advice. If a mole or an area of skin concerns you, see a doctor.
