Today Overview
See current UV, daily peak, weather, temperature, feels-like temperature and a practical recommendation for the day.
UV, SPF and outdoor care
Make more cautious choices outdoors.
UV, weather, SPF, hydration, shade and your local profile in one calm iPhone app.
BiutimiSun combines current Apple Weather UV and weather data with your local sun profile, SPF and hydration check-ins, recent sun feedback and a manually selected environment. Use Free Mode to track time outdoors and shade breaks, or build a guided body-area plan. Guidance stays conservative and never promises a guaranteed safe time in the sun.

Privacy and important note
No account, ads, subscription, third-party analytics or cross-app tracking. Profile, session, SPF, hydration, recovery and weather-cache data stay on the device until you export or delete them.
To provide local UV and weather, BiutimiSun sends the device’s approximate location directly to Apple Weather through WeatherKit. Biutimi does not receive or store it on its servers.
BiutimiSun is a general wellness app, not a medical device. It does not diagnose, treat or prevent disease and does not guarantee a safe time in the sun. Weather and UV data may be unavailable, delayed or approximate. Use your own judgment, follow sunscreen instructions and consult a qualified professional when needed.
