"It puts calls and notifications on your wrist for the price of a single Fitbit band."
The 'Answer/Make Calls' feature means this watch has a built-in speaker and microphone, functioning as a low-power Bluetooth headset on your wrist. It uses your phone's cellular connection to place the call.
This is for the smartwatch-curious who want to try basic notifications, step counting, and on-wrist calls without spending hundreds of dollars. It serves as a functional, low-risk introduction to the category or a simple notification device.
Anyone needing reliable or accurate data for fitness training or health monitoring should invest in a device with proven sensors. Users expecting a polished, fast software experience like that from Apple or Samsung will be disappointed.
