Jawbone’s Up24 line of fitness trackers are bracelets you can wear to monitor your steps, distance traveled, and other activity. Pair an Up24 with your smartphone and you can keep track of your activity and see if you’re meeting your fitness goals.
But you don’t actually need a Jawbone Up24 to use the company’s mobile app anymore.
The latest version of Up for iOS is designed to use sensors in Apple’s latest iPhone models instead.
If you have an iPhone 5s or later you can use the Up app to count steps andtrakc other activities. You can also connect with other apps such as RunKeeper or MyFitnessPal to share data using Apple’s Health and HealthKit integration.
There are still reasons to use a dedicated fitness tracker like the Up24. It has a battery that lasts for up to 2 weeks while you’ll probably have to charge your iPhone every day or two.
A wearable fitness tracker can also go places a smartphone typically doesn’t. You might not want to take your phone to the gym, out for a run, or in the shower, for instance. And a wearable device probably does a better job of tracking sleep quality.
But with fitness trackers like the Jawbone Up24 selling for as much as $150, a free app that works with gear you may already have (like a smartphone) could be a lot more attractive for folks with just a casual interest in the whole quantified self/activity tracking thing.
