## What is Shade?

Shade tells you how long you have in today's sun before your skin starts to burn.

It does one sum. Your skin type sets how much UV your skin can take before it reddens. Today's UV forecast, your location, the time of day and what you are standing on set how fast that allowance is spent. Divide one by the other and you have a countdown in minutes. It runs down faster when the UV is climbing, and it keeps counting if you lose signal.

Four questions about your skin, about forty seconds, once. Skin reaction, hair, eyes and freckling. Shade shows you the arithmetic with your own numbers in it, so you can check it rather than take it on trust.

What it does

- A burn budget for today, in minutes, drawn along the sun's path across the sky.
- Sunscreen tracking. Tell Shade when you put it on and it models what it is worth at the thickness people actually apply, which is far less than the number on the bottle, and it assumes the film wears off after about two hours, sooner after a swim.
- A vitamin D window, so you can see when the sun is high enough to make it, and when that is also when you burn fastest.
- Planning ahead. Move the marker along the day to see how many minutes you would have if you went out at 15:20 instead. After dark it shows tomorrow's windows.
- A Lock Screen Live Activity and Home Screen widgets, so a session in the sun is something you glance at rather than open an app to check.
- Notifications as your budget runs down, and a reminder when sunscreen is due again.

What it does not do

Shade has no account, no ads and no analytics. The only thing that leaves your phone is your approximate location, sent to the forecast service to fetch UV for where you are. Your skin answers, your sessions and everything the app has learned stay on the device. Deleting the app deletes all of it.

Shade can read your date of birth from Apple Health to save you answering one age question. It is optional, it reads nothing else, and it stays on the phone.

Advisory, not medical advice

The countdown is an estimate. It has looked at a forecast and at four answers you gave once; it has not looked at your skin. Shade is not a medical device and does not diagnose or treat anything. If your skin feels hot, get out of the sun, whatever the number says. The How this works screen in the app sets out the method, where the UV data comes from and what the model leaves out.

UV data comes from the Copernicus Atmosphere Monitoring Service, delivered by Open-Meteo.

Shade is free.
