Suntic
UV index app
A UV index app that tells you when to cover up
Suntic shows the live UV index for your exact location and turns it into clear guidance, so you know when it's safe to be out and when to seek shade.
A good UV index app does more than show a number. It reads the real-time ultraviolet level for your location, explains what that level means for your skin, and tells you what to do about it. That's exactly how Suntic is built.
What Suntic gives you
- Real-time UV index for your precise location, from Apple Weather, updated through the day.
- 10-day UV forecast so you can plan beach days, runs and trips around the sun.
- Home & Lock Screen widgets for a glanceable UV reading.
- Safe-sun estimates and reminders based on your skin type and SPF.
How it works
- Set your skin type and allow location so Suntic can fetch local UV.
- Open the app (or glance at a widget) to see today's UV index.
- Follow the guidance: when to apply SPF, when to seek shade, and how long you can safely stay out.

FAQ
FAQ
What is a UV index app?
A UV index app shows the current strength of the sun's ultraviolet radiation for your location, usually on a 0-11+ scale, and advises when to protect your skin. Suntic adds a 10-day forecast, widgets and personalized safe-sun estimates.
Is there a free UV index app?
Yes. Suntic is free to download and includes today's UV index, a 3-day forecast and widgets. Suntic Pro adds the full 10-day forecast and more.
How accurate is the UV reading?
Suntic uses Apple Weather (WeatherKit) data for your location. Readings are reliable guidance, but clouds, altitude and reflective surfaces affect real exposure, so treat them as estimates.
