One of the latest entrants to the crowded wearables market is an activity tracker that you might actually want to wear on a night out. The Wellograph, a device with a sapphire crystal display, features a heart rate monitor and an activity tracker, and -- gasp -- it's a standalone device, with no smartphone integration to speak of beyond syncing with Bluetooth 4.0.
Sarasin Art Booppanon, CEO of Wellograph, told us his product stands out from other activity trackers by displaying information such as steps taken and heartbeats per minute in graph form (rather than simply displaying digits). Another distinguishing feature: the sapphire crystal display, allegedly the first to appear on a moderately priced consumer product. This type of screen is known for its scratch-resistance, and while that's not something we could easily put to the test here at CES Unveiled, we can tell you it looked (and felt) pretty sturdy.
