The device was announced at MWC Shanghai and brings about features that are present on a smartphone such as in-built 3G SIM support that enables the user to make/receive calls. Also, the  IRist includes an app called iConnect that syncs with the user’s smartphone, offering information on missed calls, unread messages, and call logs as well. In other features, the IRist includes a feature called the voice assistant that sends emails, messages, dial numbers, opens and closes apps at the command of the user’s voice. A fully functional keyboard further adds to ease of use. Also, the smartwatch comes with a Bluetooth headset that can be unplugged to take calls or listen to music. In terms of specifications, the IRist has a clear 240 x 240 resolution that reproduces 16 million colors. It also comes built-in with a 5MP camera along with a face detection feature. The smartwatch is powered by a 1.2 GHz dual-core processor which runs on Android KitKat 4.4.2 with access to the Google Play S
