Description

The sun-a-wear system consists of a solar-powered, portable sensor and exclusive access to the sun-a-wear app.

The Tracker: The sun-a-wear tracker is a lightweight sensor that can be clipped onto your clothing or accessories to measure the sun's UV rays.

The App: The sun-a-wear app syncs with the tracker and suggests protective measures as well as displays the total radiation dose that has accumulated throughout the day. You can set your UV dose limit in the app and it will inform you once you have reached it. The sun-a-wear app also includes a knowledge base section with informative articles on skin health, sun protection, and more.

How it works

  1. Wear your sensor on an area of your body that is heavily exposed to the sun.
  2. Set your UV dose limit, and the app will notify you when you reach it.
  3. Receive recommendations on protective measures based on your location and time of day.
  4. Log when you apply your sunscreen in the sun-a-wear app, and it will remind you when it's time to reapply.
  5. Use sun-a-wear for yourself and your loved ones. Manage up to 4 sensors at the same time conveniently in the app.

Great addition to my health tech ecosystem

As someone who regularly uses fitness trackers, smart rings, and other health-focused technology, I’m always looking for tools that offer actionable insights and promote better habits. I wanted a way to track my daily sun exposure, not just for vitamin D, but also to build more awareness around my outdoor time.

While I considered getting an Apple Watch for this purpose, I didn’t want to add another bulky device to my wrist since I already rely on a Garmin smartwatch for my fitness tracking. After researching alternatives, I came across the Sun-a-wear UV sensor, and I’m glad I gave it a try.

This device goes beyond what most wearables offer. One of its standout features is personalized recommendations based on your skin tone, a major plus that even the Apple Watch doesn’t currently provide. It has helped me realize how little sun exposure I get most days, and I now make a conscious effort to spend time outside every morning. The real-time UV alerts and reminders to apply sunscreen or seek shade are also extremely helpful, although I haven't yet reached those thresholds myself.

Initially, I wore the sensor on my shirt collar and hat, but the company generously included a free wristband with my purchase. I now wear it on my non-dominant wrist during the daytime. Impressively, the sensor can distinguish between being indoors, outdoors, and even in the shade, adding another level of accuracy to its readings.

The only feature I’d love to see added is the ability to sync UV exposure data with Apple Health, specifically total time in sunlight and UV exposure scores. For now, I log that information manually, which is manageable but would be much more convenient with native app integration.

I also reached out to the support team with a feature request and found them responsive and helpful, which adds to my confidence in the product and the company behind it.

Keep up the great work, Sun-a-wear team! I’m excited to see what new features and integrations you bring to the app. There's so much potential here especially for health tech enthusiasts and biohackers like myself.

A Sigh of Relief!

It's such a relief with Sun-A-Wear's mobile UV tracker! I feel a sense of safety knowing I can be prepared going out into the sun as a Stage IV melanoma survivor.

Using this daily and loving it

I just received my sun-a-wear yesterday and I’m OBSESSED. Not only did it ship insanely fast, it connected easily to the app and really works. I just ordered the bracelet too, after I realized how much it had to offer. Im an aesthetician in Arizona and being protected from the sun is huge priority. This device makes it easy and gives me reassurance. Im telling everyone I know about you guys! Thank you for creating a great product!! 👏

Essential tool for sun protection for me as a Dermatology Physician Associate

I highly recommend the sun-a-wear device. Its real-time UV monitoring and personalized protection tips make it an invaluable tool for preventing skin cancer and premature aging. I encourage friends, family, and patients to incorporate it into their daily routines.

Set it and forget it

The sun-a-wear sensor, an effortless UV radiation measurement device, remains comfortably worn on the body, allowing you to set it and forget it while it works in the sunlight.

Understanding UV index and dose

The UV index measures radiation intensity at a specific time, but the impact of UV radiation depends on total exposure. To assess accumulated UV over time, we use the UV dose — a measure indicating the overall radiation amount. This measure helps estimate the sun’s effects on the body.

What does the sensor measure?

The sun-a-wear sensor measures the UV index at irregular intervals. This depends on how much light reaches its solar cell. When the sensor is in the sun, it measures every 5 seconds. In the shade, it does this about every 20 seconds. The sun-a-wear app adds up the measurements to create a UV dose.

Worn on the body, the sun-a-wear tracker accurately measures UV radiation in the sunlight, ensuring you stay protected wherever you go.

The sun-a-wear sensor is waterproof, allowing accurate measurement of UV radiation even in wet conditions.
