* Battery Saver is a mode that can be enabled under Settings that turns the screen dark, disables touch input from the screen and locks sleep mode when a device is turned upside down. This mode makes it easier to have the app track your steps while not having your phone in your hand all the time. Despite the feature only requiring devices to have accelerators (which virtually all smart phones and tablets have....) this feature seems to only actually work in common flagship phones. Enabling the feature on most non-flagship phones does absolutely nothing.
