Use Case
You train outdoors because you love it. But UV exposure during long runs, rides, and workouts adds up fast. SunGlow helps you track your sun exposure so you can train smart, get a natural tan, and avoid burns that compromise your recovery.
Your Garmin, Strava, or Apple Watch tracks every metric imaginable — heart rate, pace, cadence, elevation, power output, VO2 max estimates. But none of them track UV exposure during your workout, even though it's one of the few environmental factors that can directly compromise your recovery and long-term health. Weather apps can show the UV index before you head out, but they don't integrate with your workout. You check the weather, start your run, and by the time you're done, you've forgotten the UV reading and have no idea how much cumulative exposure you absorbed. Fitness apps are built for performance metrics, not environmental health tracking. They'll tell you if your heart rate was too high but won't tell you if your UV exposure was too much. For outdoor athletes, this is a blind spot that SunGlow fills.
SunGlow doesn't replace your fitness tracker — it complements it by covering the one thing your Garmin or Apple Watch ignores: UV exposure. Before your workout, check SunGlow for the current UV index. This helps you decide whether to apply sunscreen, adjust your route for shade, or shift your workout timing if UV is extreme. During your workout, SunGlow's session timer can run alongside your fitness app. Start a tanning/exposure session when you begin your outdoor training, and the app logs the duration at the current UV level. Over time, this builds a picture of your weekly UV exposure from training alone — data you simply can't get anywhere else. For athletes who train outdoors daily, the cumulative tracking is especially valuable. Five 90-minute morning runs at UV 4 adds up to significant weekly exposure. SunGlow helps you see this total picture and decide when you might need extra protection or a day of indoor training. The AI skin tone analysis is a bonus for outdoor athletes: track your natural 'training tan' over the season. Many athletes develop a distinctive outdoor tan from their sport — runner's tan lines, cyclist's arm tan — and SunGlow lets you track how your skin tone evolves throughout your training season.
Open SunGlow before heading out. If UV is 5+, apply sunscreen to all exposed areas. If UV is 3-4, make a judgment call based on your session length. If UV is below 3, you're likely fine for moderate exposure. This 30-second check prevents the post-workout 'I didn't realize it was that sunny' regret.
Hit start on your SunGlow session timer when you begin your outdoor workout. This runs in the background and logs your UV exposure duration. Your fitness app tracks performance; SunGlow tracks sun.
If your workout exceeds 90 minutes and you applied sunscreen at the start, reapply at your water/nutrition stop. Sweat degrades protection faster than clock time suggests. SunGlow's timer reminds you how long you've been exposed.
Stop your SunGlow session when you finish training. The app logs the duration and UV conditions. Over a training week, this data reveals your total outdoor UV exposure — something no fitness platform tracks.
Review your weekly UV exposure from training. If it's been a high-UV week with daily outdoor sessions, consider an indoor workout or extra protection for the next few days. Use AI skin tone analysis to check if your training tan is developing evenly.
Make a pre-workout UV check part of your routine, right after checking the weather. It takes 10 seconds and can save you from a sunburn that ruins your next training day.
Run SunGlow sessions alongside your fitness app during outdoor workouts. Over a training block, the cumulative UV data gives you insights no fitness app provides.
Use the AI face tone analysis monthly to track your outdoor tan progression through the training season. It's a fun way to see the physical evidence of your outdoor training volume.
On high-UV days (6+), consider shifting your workout earlier or later. A 6 AM run at UV 2 gives you the same fitness benefit as a noon run at UV 9, but with far less sun risk.
Keep sunscreen in your training bag or hydration vest. The best protection strategy fails if you don't have sunscreen with you when conditions change mid-workout.
