Overview
A first-time smartwatch shopper gets a rectangular touchscreen watch that pairs over Bluetooth through the Da Fit app. Calls and app messages show on the wrist, and the silicone band carries a magnetic charging connection.
Water resistance, a week of battery and a wide sports list make this an easy daily tracker for a phone you already own. The seller copy contradicts itself on screen size and cell capacity, and GPS comes from the phone rather than the watch.
Who it's for
A casual user who wants calls, messages and basic health readings glanced at on the wrist. Gym visitors and swimmers can use the sport modes. Anyone wanting independent GPS, stored music or a phone-free watch should look at a different class of device.
Pros and cons
- Touchscreen with more than a few watch faces
- Water resistance suits hand washing and swimming
- Magnetic charging cable in the box
- Works with both Android and iOS phones
- Listing gives two screen sizes
- Battery capacity stated two different ways
- GPS depends on the paired phone
- Health readings are not medical grade
Performance notes
Notifications arrive through the Da Fit app, so the phone must stay in Bluetooth range with call and message permission enabled. Heart rate, sleep, blood pressure and blood oxygen readings come from the wrist sensors and are read on the watch or in the app. Battery runtime depends on how often the screen wakes and how many notifications arrive.
