Lynwo BT01: A sub-US$20 smartwatch with IP68 certification, a heart rate monitor and onboard GPS

The BT01 may be affordable, but that has not stopped Lynwo from including a plethora of features. The smartwatch is compatible with Android 4.4 and iOS 8.4 or newer through the WearFit2.0 app and Bluetooth 4.0. There is also a 1.3-inch IPS colour touchscreen that resolves natively at 240 x 240 pixels. Powering the BT01 is a 150 mAh battery that Lynwo claims can last up to seven days of use between charges or up to fifteen days if you leave the smartwatch on standby. The smartwatch charges via two circular pins to which the bundled charging cable magnetically attaches.

The smartwatch is also IP68 certified against dust and water, so you need not worry when exercising with the BT01. To that end, the smartwatch supports multiple activity modes, the details of which it can track with a heart rate monitor, a body temperature monitor, a step counter and blood oxygen monitor among other features. There is also built-in GPS.

The Lynwo BT01 is available to order from Banggood. The retailer states that it will begin shipping the smartwatch from July 14. The smartwatch is available in six colours and two strap types; all versions cost US$17.99.
