SunDeck Outdoor tanning guide

UV Timer & Tan Session Planner

Free · Designed for iPad. Not verified for macOS.

SunDeck is a playful outdoor tanning timer for people who want a clearer, more structured way to manage time in the sun. Before you begin, SunDeck uses your location and local time to calculate a conservative offline clear-sky UV estimate. This is not live weather data and cannot account for clouds, rain, shade, reflection, or rapidly changing conditions. Always confirm the actual conditions around you. Choose one of six character guides, set your SPF and session preference, then follow visual steps for sunscreen, tanning positions, shade breaks, hydration, and recovery. Situation-specific illustrations make each cue easy to recognize at a glance. Features: • Six distinct character guides • Conservative clear-sky UV estimate based on location and local time • Guided tanning positions and session timer • SPF, tanning oil, shade-break, and hydration steps • Character-led weather and safety states • Local session history and photo diary • Optional local reminders SunDeck is designed for outdoor tanning only. It does not provide medical advice, guarantee tanning results, or prevent sunburn. Use sunscreen appropriately, avoid overexposure, and stop immediately if your skin feels uncomfortable.
