All Specs Wyze makes some of most affordable smart home devices on the market, like light bulbs and home security cameras. If you have a bunch of Wyze gadgets, you're the prime customer for the $20 Wyze Watch, which lets you set up shortcuts to control them from your wrist with a few taps. This inexpensive Apple Watch lookalike also boasts a pulse oximeter to read your blood oxygen saturation (SpO2) level, and can help you keep tabs on your calorie burn, heart rate, sleep, steps, and the date of your next period. Aside from the SpO2 sensor, however, we found its health and fitness tracking capabilities to be lackluster in testing. And apart from its smart home controls, this is about as basic as a smartwatch get.
