The toolkit
Six things Soleil does well
- Now
Live UV
The index where you are, its category and today’s peak — with the source and how fresh the reading is shown beside it.
- Personal
Protection check
Your skin type, SPF, clothing and the current conditions become one clear thing to do next.
- Reminders
Sunscreen timing
Two hours at most, and sooner after swimming, sweating or towel-drying. Reapplying never resets your time outside.
- Outside
Sun timer
Start an outing and Soleil keeps elapsed time, each person’s cover and their reminders together. Daily Glow adds an optional guided routine.
- Your people
Family
Profiles for everyone you look after, each with their own skin type and their own reapply reminders.
- Apple Watch
Real Sun
Time in Daylight from your Watch, drawn against the day’s UV curve.
How it works
A sunnier day in four moves
-
Check the sky
See the live UV index, its category and when today peaks.
-
Choose your cover
Set skin type, SPF, clothing and shade. The protection check adjusts.
-
Start the day
Start the Sun timer for whoever is outside and keep sunscreen timing organised.
-
See your Real Sun
Look back at when your daylight actually happened.
UV now
The UV answer, in one look
- One card
Open Soleil and the sky answers first.
No dashboard to decode. Your Day opens on the live UV index for where you are.
- The reading
The index, its category, and how fresh it is.
UV and conditions come from Apple WeatherKit, with the source and time of the reading shown.
- The day’s shape
Today’s peak, cloud cover, humidity.
The hourly curve shows when the strong part of the day arrives — before you go out in it.
- Your check
What to do now, not how long you may stay.
Your skin type and SPF turn the reading into a timely protection check. Soleil never presents time as permission.

- Beach days
- Garden afternoons

Real Sun
Forecasts tell you what might happen. Real Sun shows the daylight you actually had.
Gentle light, low index
Daylight early in the day lands while UV is still low.
The strongest hours
Around midday the index reaches today’s high. Soleil shows how much of your daylight happened here.
Softening again
Late daylight sits on the falling side of the curve.
Real Sun reads Apple Watch Time in Daylight with your permission. Soleil never writes to Health, and daylight is never presented as an allowance.
Questions
Common questions
How long can I stay in the sun without burning?
It depends on the live UV index and your Fitzpatrick skin type: roughly 15 minutes for very fair skin at UV 6, over an hour for deeper tones. Soleil shows the live UV and turns it into a timely protection check rather than a countdown.
Read all the sun guidesWhat UV index is safe?
Below UV 3 is low risk for most people. From UV 3 upwards, the WHO recommends protection: shade, clothing and sunscreen. Soleil tells you plainly when your local UV crosses that line.
Read all the sun guidesWhat’s the best UV index for tanning?
Colour develops from about UV 3, and a moderate index of 3–5 lets skin respond gradually with lower burn risk. No UV tan is risk-free; pacing and never burning are what matter.
Read all the sun guidesHow often should I reapply sunscreen?
At least every two hours, and immediately after swimming, heavy sweating or towel-drying. Soleil schedules reapply reminders per person, sooner when you log water or towelling. Reapplying never resets your time outside.
Read all the sun guidesHow much sun do I need for vitamin D?
In summer, about 10–30 minutes of midday sun on forearms a few times a week for lighter skin; longer for deeper tones. Soleil deliberately doesn’t turn sunlight into vitamin D numbers; it records your real time outside instead.
