For the past few months, I’ve done something which is dorky even by my own dorky standards: I’ve often gone out in public with two wearable devices on my wrist. One has been a smartwatch of some sort. (At the moment, it’s Motorola’s Moto 360.) The other has usually been Jawbone’s Up 24 fitness band. Here’s why: Overall, the Up app, which works only with Jawbone’s hardware, is the richest, cleverest one I’ve found for counting steps, monitoring sleep, and logging information about what I eat. But the slinky little Up band isn’t a full-blown smartwatch, so it’s not the only wearable a gadget freak will ever need. A Jawbone spokesperson confirmed to me that the company plans to announce its decision on Tuesday, when Apple will be announcing its wearable device.
