Garmin's Vivosmart is a smart band that includes a fitness tracker and notification display from your smartphone (iOS and Android). The Vivosmart uses Futaba's flexible (curved) 1.4" 128x16 white PMOLED panel.
This device can count your steps, monitor your sleeping and calories burned and also measure the distance you've walked. The band is powered by low-energy bluethooth and can last seven days between charges. It is also waterproof up to 50 meters and is compatible with heart rate monitors and bike speed sensors.
The Vivosmart is now shipping for $170 (or $200 bundled with a heart rate monitor). In December 2014 we posted a hands-on review of the Viviosmart and its flexible display.
