Samsung’s Galaxy Watch 3 has a lot working in its favor. It’s one of the best-looking smartwatches, with a bright, circular AMOLED display. And it has new fitness aids like a running coach feature, the option to sync workouts from your TV to your wrist, better sleep tracking than earlier models and advanced health tools like an electrocardiogram (EKG or ECG) app to monitor your vitals. But it still can’t deliver on all of its health promises, and it’s battery isn’t as great as I’d hoped.
