There is a wearable for every user, whether you want to pair it with a smartphone, computer or nothing at all. For instance, the Jawbone UP requires users to pair the device with an iOS or Android™ smartphone via Bluetooth. Samsung® Gear smart watches also require smartphones, but that’s because they are designed to augment Samsung handsets, making it easier for users to access the apps loaded onto the phone. Meanwhile, Other fitness trackers work with computers connecting directly to PCs via USB and/or with smartphones (like the Moto 360) wirelessly with Bluetooth.
But if you’d prefer to sync your data with nothing at all, sparsely-featured trackers, like the Fitbit Zip, can sync with computers and phones, or simply work as standalone devices. Before you buy, explore which if any syncing method a wearable requires, and make sure it works with the equipment you already have.
