What is SupaTan?

SupaTan - Tanning & UV Index is an iPhone and Apple Watch app made by indie developer André Grillo (Supa Studio). It combines hourly UV forecasts from Apple WeatherKit with your skin type and tanning goal to tell you exactly when to start tanning, how long to stay, and when to turn over. Guided sessions send haptic flip reminders and SPF reapply alerts, and a photo log with guided self-portraits tracks your glow over time.
