Shade — UV Index & Sun Safety
Shade is an iPhone app that tracks the UV index where you are and counts down the sun time you have left. Start a session, get a warning before you burn, and see every session you've logged.
What Shade does
The UV index where you actually are
Forecast UV from Apple Weather for your location, hour by hour, so you can see when the peak lands and plan the day around it. Save the places you spend time in and switch between them.
A burn countdown, not a guess
Start a sun session and Shade counts down the time it estimates you have left. It combines the UV forecast with your skin type, applies a safety margin, and keeps adding up your exposure as the UV rises and falls. Your allowance resets at midnight.
Honest about protection
Tell Shade you're wearing sunscreen or covered up and the safe time multiplies. The app can't check, so the setting is yours to keep honest — update it when you take a layer off and the countdown stays useful.
Every session logged
Each session is saved so you can look back at how much sun you've been getting this week, not just today.
Your data stays on your phone
Sessions, settings, and cached forecasts live on your device. We don't collect them, so there's nothing of yours on our servers.
Before you rely on it
The countdown is an estimate, not a promise — nothing is measuring UV at your exact position, including Shade. Use sunscreen, clothing, and your own judgement regardless of what it says, and read the health disclaimer first.
