Bask - Vitamin D Sun Tracker

Vitamin D is the easiest deficiency to fix, but the hardest to track. Bask estimates the Vitamin D you get from sun exposure and supplements, so you can stop guessing and start hitting your goal.

Bask is a sun tracker and sun timer that reads the sky, live UV Index, weather, your skin, and what you're wearing to tell you the best time to step outside and exactly how long to stay.
