## Features

- 【NFC Pairing】The interaction interface can be accessed directly using NFC (For android). Customers without NFC function can also connect quickly through Bluetooth or WiFi.
- 【App digital monitor】The KS Fit app simultaneously displays your time, speed, steps, and calories burned. Keep track of your workout history.
- 【Detachable phone holder】The WaklingPad X21 is equipped with a detachable mobile phone holder. You can put your favorite tablet or mobile phone on the detachable stand of the treadmill and watch your favorite content while exercising.
