Then, with the help of some pretty graphs, Up Coffee estimates when the caffeine will wear off -- i.e., when you might be able to fall asleep. What's nice is that you can use the app even if you don't own an Up band; your sex and weight alone will help the software estimate what effect a cup of coffee will have. However, if you do happen to own a Jawbone Up band, you can link it up with the app and view your recent sleep data against your caffeine intake, confirming that yes, it really is a bad idea to drink java after five o'clock. Over time, the app might even challenge you to try experiments, as in, "What happens when you drink three cups instead of two?" There's only one way to find out.
Up Coffee is available today on iOS only. In an interview, VP of Product Management Travis Bogard would neither confirm nor deny plans to release it on Android; it all depends on how successful the iOS version is ("we'll see" were his exact words). In the meantime, Jawbone is also updating its regular app, the one that works with the Up and Up24 bands. Here, too, the updates are for iOS only -- for now, anyway. All told, the changes are fairly minor. These include: sunrise and sunset times in the sleep graph; the ability to create custom reminders; new "Today I Will" challenges; and "Insight Reports," which establish a connection between things like your bedtime and how many steps you're likely to take the next day. Oh, and you may also notice a change in terminology: Jawbone now says "sound sleep" instead of "deep sleep," which is technically a clinical term -- a narrowly defined one, at that. Again, if you're on iOS you can download the update today. If you're on Android, well, we can only assume that version will catch up eventually.
