The Touch is wider, has a stripe down the center of the wristband, and has a touch screen that displays time, date and current activity stats, in addition to other apps.

The Band is thinner, with a solid wristband, does not have a touch screen, and uses light bars to display your step goal progress throughout the day.

Both devices track activity (steps, distance, calories, active minutes) and sleep (duration and quality). Both devices require the Striiv Activity Tracker App, and use 
low-energy technology (BLE) to communicate with your smart phone/tablet.
