Bask - Vitamin D Sun Tracker

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

Other apps just count pills. Bask reads the sky, live UV, weather, your skin, and what you're wearing to tell you the best time to step outside and exactly how long to stay.
