The latest fitness tracker from Withings looks more like a Kindle e-reader accessory than a high-tech health gadget.

The $69.95 Go wearable sports an always-on e-ink multiscreen display that automatically tracks steps, distance, running, swimming, and sleep—all for $69.

A main screen highlights the user's level of activity: A dial increases as you progress toward the day's activity goal. Once that target is met, the central icon changes to display a digital reward.

The Go automatically recognizes various types of exercise, including walking and running; it analyzes your steps taken, distance covered, calories burned, and workout duration. Plus, the water-resistant device knows when you start swimming, and keeps track of your session. At night, Go can distinguish between light and deep sleep cycles.

Pair the wearable with the free Withings Health Mate iOS or Android app to record activity and log food intake via MyFitnessPal integration. The app also provides daily reports and advice, while users can also see how friends are faring, earn badges, and set smart reminders.

The low-power requirement of the e-ink display means the Withings Go can operate continuously for up to eight months on the device's button cell battery. The Withings Go also transforms into an analog watch face to tell the time.

"Sporting a number of industry firsts, from always-on multiple displays to dynamic activity recognition, we have once again released a product that will make activity tracking accessible for everyone," Withings CEO Cédric Hutchings said in a statement.

Available in five colors (black, blue, green, red, yellow), the Go works on the wrist, clipped to a belt or keychain, or in a pocket. The device is on display during this week's CES in Las Vegas, where visitors can stop by the Sands Expo Center for a demonstration.

If you're in the market for something a bit more high-end, Withings in November revealed the $169.95 Activité Steel.
