Screenless fitness trackers can sometimes feel like they aren't doing the job they set out to do. Sure, there's no constant stream of data to obsess over every time you turn your wrist. But in the absence of that quick peek, I find myself opening a tracker's companion appconstantlyto check on the data it's collected. In the end, I find myself spending more time staring at those charts and figures than if I took a look at the tiny screen on my wrist.
