NO.1 has released a new Smartband! The NO.1 F4 heart rate smart band has a large 0.96-inch OLED display that displays the time, and measures the number of steps, your heart rate, the distance traveled, as well as the calorie consumption. You will also be able to see more information, e.g. the battery status, directly on your wrist as well as messages from your smart phone. The data can also be easily retrieved via the touch screen of the F4 Smartband. The display is elegant and bright enough to have everything in view even in bright sunshine.

The biggest concern of any fitness tracker is the battery power. The NO.1 F4 comes with a 130 mAh battery. The manufacturer promised a standby time of maximum 10 days. The NO.1 Smartband F4 comes with a performance-efficient acceleration sensor to count your steps. Also, an optical heart rate sensor that calculates your heart rate is on board. It also comes with a Bluetooth 4.0 interface, which ensures a fast and stable connection with your smartphone.

The fitness tracker also supports the sedentary alarm function. The NO.1 Smart band F4 monitors your physical activity and warns you when you sit for long periods. It warns you via vibration and reminds you to get some fresh air or to become physically active. A sleep monitor is also included. The NO.1 bracelet is more skin-friendly and has a light weight, which helps you to wear it while you sleep without being affected. It monitors your sleep and displays the phases with light and deep sleep in the app. Of course, the unit is also waterproof. It has the IP68 certification and is up to 30 meters’ water resistant. So you can also use the Smartband for swimming or even diving. Other features include vibration of incoming calls, SMS, app notifications and the alarm clock.
