UV Tracking

Know exactly when to tan.

Sundaze pulls live UV data for your exact location and shows you an hour-by-hour breakdown of the day's intensity. See the peak window at a glance, plan your session around it, and never get caught out by a UV spike again.

  • Live UV index for your exact GPS location
  • Hourly UV chart with best tanning window highlighted
  • Temperature, humidity & cloud cover at a glance

Daily Sun Report

Your personal daily sun briefing.

Every morning Sundaze generates a written briefing on the day's tanning conditions — the peak UV window, best hour, today's tan score, and what to watch out for. Think of it as a weather report, but written specifically for tanners.

  • AI-written briefing tailored to your location daily
  • Today's tan score out of 10 + best hour of the day
  • Cloud cover, timing warnings, and SPF notes included

Smart Sessions

Set your time. Tan smart.

Before every session, Sundaze calculates a safe duration based on your skin type, current UV, and SPF. Set your target time, choose your start position, and let the timer handle the rest — with reminders to flip, reapply, and stay covered.

  • Safe duration calculated from your skin type + UV + SPF
  • Choose SPF level and starting position before you begin
  • Reapply SPF reminders based on UV conditions

Flip Tracking

Track every flip.

An even tan means timing both sides. Sundaze tracks your front and back time separately during a live session, so you always know when to flip. One tap switches positions and logs the time — no guessing, no uneven color.

  • Separate front & back timers running simultaneously
  • One-tap flip logging with full history at session end
  • Live UV and SPF display throughout your session
  • Snap a photo mid-session to capture your tan progress

Suni AI

Your personal sun advisor.

Suni is an AI built specifically for tanning. Ask her anything — what SPF to use right now, your burn time today, the best days to tan this week, or how to build a base tan before a trip. She knows your skin, your location, and your history.

  • Ask anything about tanning, SPF, UV, and your skin
  • Personalized answers based on your skin type and location
  • Multi-day tan plans generated on request

  • Create a crew and share an invite link with your group
