Up Coffee

Caffeine is everywhere — in our coffee, in our energy drinks, even in our snacks. But very few of us really know how it affects us, or how much they ingest every day. Up Coffee could change all that. Made by Jawbone, it tracks your caffeine levels throughout the day as it learns more about how your body metabolizes the drug. It even compares your intake to your quality of sleep, giving you a better look at how your body works. And while the Up fitness tracker might cost money, Up Coffee is completely free.
