About this app
Sunbathing is not a medical device and does not diagnose, treat, cure, or prevent any condition — it is informational only. Consult a healthcare professional for personal sun-safety guidance.
Tan with intention. Tell Sunbathing your skin type once, and it watches the live UV index for your location to tell you exactly how long you can safely stay out — and when to flip — before you burn.
WHAT IT DOES
• UV-aware session timing — plans your safe minutes against the real, hour-by-hour UV forecast and recomputes on the fly as the sun shifts, warning you as you approach your limit.
• Vitamin D estimation — see an estimated vitamin D figure for every session, plus weekly and lifetime totals.
• Two session types — full-body Sunbathe sessions with flip reminders, and Exposure sessions with SPF-reapply reminders.
• Adaptive burn calibration — a gentle next-morning "did your skin handle that?" check quietly tightens future recommendations if you report a burn.
• Session history — a full log with detail view, in-place editing, and delete, with dose and vitamin D recomputed automatically.
• Tan-retention chart — a 90-day view of your tan building and fading.
• Best window today — plain-language advice on the optimal time to head out.
• 7-day UV outlook — peak-UV bars for the week ahead, with a clouds-easing-it note.
• Weekly streaks — keep a consecutive-week streak going, with one missed week forgiven.
• Travel detection — a heads-up when you move somewhere the sun hits differently.
• Local reminders — flip, SPF-reapply, session-ending, and daily-limit alerts.
PRIVATE BY DESIGN
• No account, no email, no password — works anonymously from launch.
• No ads. No third-party advertising. No cross-app tracking.
• Approximate location only (rounded to about 1 km), used solely to fetch your local UV forecast.
• Export all your data to CSV, or delete everything — sessions and skin profile — with one tap, anytime.
Sunbathing is informational only and not medical advice.
