Tangens: UV Index & Tan Timer App

Tangens is a UV Index and Tan Timer app. See today’s UV, minutes until burn risk, and a guided tanning routine matched to your skin type and SPF.

Tangens is a UV Index and Tan Timer app that helps you plan safer outdoor sun time. Check today’s UV number, the hourly curve, peak time, and a burn-risk estimate for your skin type and SPF — then start a guided tanning routine with timed front and back rounds.

Instead of guessing how long to stay out, the tan timer follows a sunscreen step, exposure rounds, and a shade break so vitamin D or tanning sessions stay on a schedule.

• Burn-risk minutes based on skin type and SPF
• Guided tan timer with sunscreen, front/back rounds, and shade break
• Vitamin D and UV exposure cards
