## What is Sundial?

Sundial is the honest tanning app. Real sun science, personalized to your skin, with zero fearmongering and zero hidden fees.

Every number in Sundial is personalized to your Fitzpatrick skin type — your safe session length, when to flip sides, the SPF to wear, and your time-to-burn limit. Get a live UV index for your exact location with an hourly forecast, and let Sundial find your best tan window of the day.

LIVE UV, HOUR BY HOUR
• Real UV for your exact spot, with an hourly forecast
• Your best tan window — when UV is strong enough to glow but gentle enough not to burn
• Honest numbers, even when that number is zero

TIMERS BUILT FOR YOUR SKIN
• Personalized session length and a flip reminder for an even tan
• A hard stop before your burn limit
• Live Activity on your lock screen and Dynamic Island
• Vitamin D tracking for every session

WATCH YOUR GLOW BUILD
• Tone progress along the bronze ramp — no fake progress bars
• A selfie timeline of your tan journey
• Sun streaks, achievements, and total sun hours

TAN TOGETHER
• Pair with your partner in couples mode
• See when they're tanning and join their session
• Send a "catch the sun" nudge
• Build a shared streak and plan sun dates

AN AI COACH THAT KNOWS YOUR SKIN
• Advice based on your skin type, your sessions, and today's UV
• Ask anything from SPF picks to why your shoulders burn first

FIND YOUR SUN NEARBY
• Beaches, parks, and pools around you, with live UV and directions

HONEST PRICING
The core app is genuinely free — live UV, personalized timers, sessions, streaks, friends, and tan spots. No ads, no trial timer.
