Which category finds an increase in applications targeting health and fitness?

• A. Group IoT
• B. Industrial IoT
• C. Community IoT
• D. Personal IoT

Answer: (D)

Health and fitness apps rise when the devices collecting the data are carried or worn by individuals to track their own metrics. This fits Personal IoT, where the emphasis is on devices owned and used by a person to monitor health, activity, and wellness—like fitness trackers, smartwatches, heart-rate monitors, and connected scales. Industrial IoT focuses on factories, machines, and large-scale processes, not personal health data. Community IoT covers shared public or neighborhood infrastructure, which isn’t the primary driver for consumer health trends. Group IoT involves coordinated devices for a specific group, but the dominant growth in health and fitness comes from personal devices and the personal data they generate. So, Personal IoT is the category seeing an increase in health and fitness applications.
