Jawbone's 'Up Coffee' app tracks your caffeine intake, estimates when you'll finally be able to sleep
Ah, caffeine. So addictive. So energizing. So unhealthy. It's no secret that coffee lends itself to spurts of early-morning productivity, only to be followed by mid-afternoon slumps. And yet, we're somehow always surprised when that 4PM frappuccino keeps us up past a reasonable hour. "Up Coffee," a new iPhone app from Jawbone, probably won't wean you off the good stuff, but it might take the surprise out of your next coffee coma. Here's how it works: you enter a few specifics, including your sex, weight and caffeine tolerance, and then it's your job to start logging. And let's be clear here: this isn't just a coffee-tracker, but a caffeine app, so in addition to all those coffees you consume throughout the day, you also should be logging any late-night Red Bulls.
