Sun, smarter. Sundoze tells you the right amount of sun for vitamin D, a safe day out, or a steady tan — adjusted for your skin type, the altitude you're at, and where in the world you are. Most UV index apps pick a side. Sundoze has two modes for two real sun goals: ▸ MORE SUN — when you're chasing vitamin D or a steady tan. We show you the safe window before you burn. No moralizing. No "just stay inside." ▸ LESS SUN — when you just want to be outside without skin damage. We track your burn time, remind you to reapply SPF, and quietly add it up over the season. ▸ TRAVEL MODE Going somewhere new? Sundoze shows exactly how the UV index compares to home — adjusted for your skin type. "Phoenix runs hotter than home — pack SPF 50+" isn't generic advice. It's your skin, your math. ▸ ALTITUDE MATH UV intensifies about 12% per 1000 m of elevation. Snow reflects up to 94%. Most apps don't correct for this. Sundoze does. Built for the Alps and Rockies, not just the beach. ▸ WINTER MODE Northern winters mean the UV index is too low for vitamin D from sun alone. Sundoze switches into supplement-tracking mode automatically. 80% of Europeans are insufficient through winter. We help you stay consistent. ▸ SCIENCE Burn-time math uses the Fitzpatrick I–VI skin-type system. Calibrated against the same research dermatologists use. Not generic warnings — your skin, your numbers. ▸ DESIGN Editorial typography, calm palette, no doomscroll, no panic colors. Sundoze is built to be glanceable in bright sun. ▸ PRO Unlocks unlimited Travel cities, full Winter Mode tracking, and the 7-day UV index forecast for every location. Free trial included. Built in Switzerland. No ads. No tracking. Just the math. Terms of Use: https://arytec.ch/sundoze/terms Privacy Policy: https://arytec.ch/sundoze/privacy

Verdict
The clearest difference is rating: QUIT at 4.0 against UV Index's 1.0. QUIT also leads on update cadence (every 4 days vs every 3 weeks) and ratings volume (8 vs 1). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. QUIT sells 3 in-app purchases, starting at $9.99 per 7 days and UV Index sells 2 in-app purchases, starting at $12.99 per year. Whichever you choose, the download price is not the number that matters.
QUIT holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: QUIT has 8 ratings behind it against 1, so its average is the more settled of the two.
QUIT ships an update every 4 days, UV Index every 3 weeks. Both last shipped on October 24, 2026.
