"It's a $14 notification screen that looks like a health tracker."
The 'HD Touchscreen' and '110+ Sport Modes' are checklist features. In reality, this is a basic notification device with step counting; its fitness and health data will be highly inaccurate and should not be used for training.
This is for someone who wants the aesthetic of a smartwatch and basic notifications for a price that is functionally disposable. It may serve as a low-risk first watch for a child where loss or damage is a high probability.
Anyone seeking reliable fitness tracking, accurate health metrics, or a responsive user experience should skip this. If you care about your health data, invest in a device from a brand with a proven software ecosystem.
