Smartwatches

A smartwatch puts calls, messages, step counts, heart rate and sleep tracking on your wrist. Before you buy, check three things: whether it works with your phone (Android or iPhone), how many days the battery lasts with your habits, and whether the screen is readable in sunlight. Only models with a speaker and microphone can take calls directly; cheaper ones simply vibrate. Health readings on a watch are for reference only and do not replace medical devices. The list below is ranked by the independent usdxu score, built from real sales and buyer ratings.
