SunTanApp helps you tan smarter by tracking your sun exposure in real time using UV-based calculations, personalized skin settings, and guided tanning timers. Instead of guessing how long you have been in the sun, SunTanApp helps you manage each tanning session with a clear exposure tracker, rotation reminders, sunscreen timing, and session history. Whether you are lying by the pool, spending time at the beach, or getting sun in the backyard, SunTanApp is designed to help you stay more aware of your UV exposure and build more even tanning habits. Features include: • UV-based exposure tracking - SunTanApp uses current UV conditions to estimate your sun exposure over time. • Personalized tanning guidance - Customize your session based on your skin type, base tan, sunscreen use, and tanning goals. • Rotation timer - Get reminders to switch sides so you can work toward a more even tan. • Sunscreen timer - Track when sunscreen protection may need attention during your session. • Cloud and sun adjustments - Account for changing sky conditions during your tanning session. • Side-by-side session tracking - Track exposure separately for each side of your body. • TDU exposure system - SunTanApp uses Tanning Dosage Units to give you a clearer way to understand cumulative UV exposure during a session. • Session progress display - See your estimated exposure, remaining time, and tanning progress while you are outside. SunTanApp is not a substitute for medical advice, and it does not guarantee prevention of sunburn, skin damage, or UV-related health risks. Always use sunscreen appropriately, follow product directions, and practice responsible sun safety. SunTanApp: tan smarter, rotate evenly, and stay aware of your time in the sun.
