At present we can be said it, A smartwatch is a wearable computer in the form of a watch. Modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides for management and telemetry (such as long-term biomonitoring). Early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing. After 2010 smartwatches have more general functionality closer to smartphones, including mobile apps, a mobile operating system, and WiFi/Bluetooth connectivity. The first digital watch, which debuted in 1972, was the Pulsar manufactured by Hamilton Watch Company. Now Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. In recent times we saw that Smartwatches, smart bands, and fitness trackers started to become popular in Bangladesh.
