Google's Two New Fitness Bands: $99 Without a Screen, $179 With One

Google sells two Fitbit wrist bands. The $99 Air has no screen and is controlled from the Google Health phone app. The $179 Edge has a 1.34-inch oval touch screen and a side button you press. Both check your pulse with light and resist dust and water. Edge lasts seven days on a charge if the screen sleeps when idle.
