Suntide: UV Index & Tan Timer

Suntide builds a simple, personal sun plan for your skin and your destination.

Answer a few quick questions about your skin tone, SPF, activity, and goals. Suntide turns local UV forecasts into practical guidance: the best sun windows, guided tan timer sessions, SPF reapply reminders, and shade-break prompts — with a heads-up on high-UV days.
