Location-based UV forecast
See your real-time UV index and a 24-hour forecast for your exact location, powered by Apple WeatherKit. High-UV hours are flagged so you know when to cover up.
Sun protection, made simple
Protect your skin, every sunny day.
Sommar reads your local UV index, estimates how long your sunscreen lasts, and nudges you to reapply before it runs out — so protecting your skin becomes a habit, not a guess.

Features
Everything you need to stay covered
Sommar turns sun protection into a simple daily rhythm — from the moment you check the UV to the reminder that tells you it's time to reapply.
Suggested Protection Time
Sommar estimates how long your protection lasts from your sunscreen and conditions, then counts down to your next reapplication.
One-tap SPF logging
Log every application in a tap. Each log connects the day's UV conditions to your routine and builds a protection timeline you can trust.
Skin health history
Review your last 7 days at a glance: days logged, estimated protected time, applications, and any gaps in your coverage.
Sunscreen inventory
Track your products and remaining stock so a bottle running low never catches you off guard mid-summer.
Progress & consistency
A calendar that celebrates your streak and shows how consistently you protect your skin, month after month.
Widgets & Live Activities
Keep your protection status and reapplication timer glanceable on your Home Screen, Lock Screen, and Dynamic Island.
Private by design
Your protection history and inventory live on your device. Sommar is built to keep your data yours.

FAQ
Questions, answered
A few things people often ask before they start protecting with Sommar.
Is Sommar a substitute for sunscreen or medical advice?
No. Sommar is a planning and reminder tool — not medical advice or a medical device. UV readings and protection durations are estimates that can be affected by weather, water, sweat, activity, and how you apply. Always follow product guidance and consult a professional for medical concerns.
Where does the UV data come from?
Sommar uses Apple WeatherKit to provide UV and weather information for your location, when you grant location permission.
Do I need to share my location?
Location is optional, but it powers the most useful features. Without it, some UV features may be limited. You can grant or withdraw permission at any time in iOS Settings.
How does Suggested Protection Time work?
Sommar estimates how long your protection lasts based on your sunscreen and the conditions, then reminds you to reapply before it runs out. It's guidance to help you build a routine, not a guarantee.
Is my data private?
Your protection history and inventory are stored on your device. See our Privacy Policy for the full details on what is processed and why.
How much does Sommar cost?
Sommar is free to use. Sommar Glow is an optional subscription that unlocks premium insights and glowing streak badges, billed through your Apple account.
