A wearable fitness tracker is a device, which uses sensors to track user movement, orientation, and rotation. This device gathers data and transforms it into calories, steps, sleep quality, and other activities that the user performs. Many trackers also have an 'altimeter' sensor, which measures altitude to track the number of flights of stairs climbed. These trackers can simply figure whether the user is running or not. In addition, the alarm in the tracker reminds about a variety of things such as drinking enough water, standing, walking, completing the number of steps, sleeping on the right time, and others. This device provides solutions to individuals who are involved in working toward a precise health & fitness goal.

Chatbots are computer programs that allow humans to interact and clear various queries relating to various topics, and thereby benefit from the technology. Humans send inputs via texts, messages, voices, and some other gestures to enable interaction with chatbots. Over the past decade, chatbots were employed only in providing customer service; in recent years, chatbots have evolved significantly and are penetrating numerous sectors. Many industries have realized the power of conversations and are thereby investing funds to increase the adoption of chatbots. The industries are exploring the major advantages that these chatbots can provide to their businesses; in this context, AI-driven chatbots are being widely popularized and different sectors are showing an interest in adopting them in their mainstream operations.
