Daylight scores every day from 1 to 1000 for how good it is to be outside, tuned to your skin type and your ideal temperature. One look tells you what today is worth.
Daylight answers one question every morning: how good is it actually going to be outside today?
It does that with the Daylight Score, a single number from 1 to 1000 that is personalised to you. Tell Daylight your ideal temperature and your skin type, and it blends UV safety, temperature comfort, sky conditions and wind into one honest score. Bad weather caps the score, so a high number really does mean a nicer day outside.
THE DAYLIGHT SCORE
• A personalised score from 1 to 1000, tuned to your skin and your comfort
• See exactly what is holding the day back, whether that is high UV, rain, cold or wind
• Tiers from Hazardous to Excellent, so the meaning is clear at a glance
• Choose a score style: Balanced, UV Cautious, Comfort Focused, Weather Strict, or build your own
