PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Check today's UV before you go outside — and know exactly how long your skin can take it. SolTrack turns a raw UV number into a personal answer. Take the quick skin quiz or use the on-device camera scan to find your Fitzpatrick skin type (I–VI), and every screen adapts: your estimated burn time, the SPF to wear, when to reapply, and when today's peak window makes shade the only smart option. The UV curve is computed right on your phone from the sun's position at your location — no weather account, no network needed — and the app is upfront that it is a clear-sky estimate, not a sensor reading. WHAT YOU GET • Today's estimated UV curve for your location with the peak window flagged — one glance before you leave the house • A burn-time estimate built for YOUR skin type: "34 min unprotected at UV 7", not a generic warning • A sun session timer that ends before the damage does, with a notification the moment your window is up • Sunscreen reapply reminders every 2 hours — plus the SPF you should actually be wearing right now • A sun journal: log each session with duration, UV and SPF, then watch your weekly exposure chart fill in • A Glow preview: a subtle on-device bronze filter shows a sun-kissed look on your photo — without earning it in the sun PERFECT FOR • Fair-skinned people who burn in twenty minutes and are tired of finding out the hard way • Beach and pool days where "I'll reapply later" always turns into a lobster evening • Hikers and travellers at altitude, where UV climbs roughly 10% per 1,000 m — SolTrack adjusts for elevation • Anyone who wants a record of their sun exposure over weeks instead of a guess WHY NOT JUST A WEATHER APP? A weather app shows everyone the same UV number. It does not know your skin type, will not count down your burn time, will not ping you to reapply sunscreen, and keeps no record of your sessions. SolTrack does all four — and cites its sources (WHO UV Index guide, FDA sunscreen rules, dermatology guidance) right inside the app. PRIVATE BY DEFAULT No account. No cloud. Skin scans and Glow photos are processed entirely on your device and never uploaded. Your session log lives in local storage only, and location is used solely to compute the sun's position. PREMIUM (PURCHASE REQUIRED) SolTrack requires a purchase to use: a Weekly or Yearly subscription, or a one-time Lifetime unlock. Every plan includes all features — UV estimates, skin typing, timers, reminders, the journal, and the Glow preview. SolTrack is guidance, not medical advice, and it will be straight with you: there is no safe tan. Download SolTrack and check your UV before your next minute in the sun.
