With QSun, balance your sun exposure and vitamin D, avoid sunburns, find the current UV (ultraviolet) index, and get personal sun safety tips for healthy & young skin. QSun lets you know when it’s time to seek sun protection, and helps you prevent skin aging and skin cancer. The QSun app is 100% FREE with no ads, and is already helping thousands of people worldwide enjoy a healthier life.

Use your QSun/QTemp device with the QSun app to access real-time UV index and temperature readings from exactly where you are standing. The QSun app works without a QSun device, but using a QSun/QTemp device makes for a more personalized experience. Using a QSun device will give you more accurate sun protection tips. You’ll also be able to track your personal sun exposure history, including times when you were outside, inside, and in the shade. The device was made possible with Kickstarter.

QSun isn’t your ordinary weather app. Based on the UV index, it lets you know when it’s time to seek sun protection. Remember, there’s nothing healthy about tanning. Let QSun help you prevent sunburn, skin aging and skin cancer.

My go-to app


As someone with Solar Urticaria (literally allergic to sunlight) this is my go-to app for making sure I don’t have a reaction when I go outside. Super informative, tracks your specific skin type, and sends you sunscreen and clothing recommendations based on the index. Even gives you a timer for how long your exposure can last before you start to burn. I absolutely love it and its become an essential app for me. I highly recommend it.

I love the app but

I love it, but it suddenly stopped working for some reason :/ it gets stuck in the loading image (that little orange circle ). The notifications are still operational, but I can’t access the app.

What a great app! Highly recommended to anyone!

The app is a must have for an outdoor adventurist like me. Everyone who cares about skin health and safe sun exposure should definitely get this app! With useful features like safe sun time, UVI tracking, weather forecast, I no longer need to worry about getting sunburned or forgetting to bring an unbrella. I am using the app every day and I cannot live without it anymore! Keep up the good work!
