Choose Features That Fit Your Routine
Training — Compare stated sports modes, step and calorie tracking, and GPS. Connected GPS requires a phone; a listing that only says GPS does not establish how it works.
Everyday use — Check phone compatibility, battery life, charging requirements and the manufacturer's water-use guidance for the exact model.
Health features — Heart rate, sleep, blood oxygen and ECG are different features. A general health or wellness label does not confirm any particular sensor. Blood-pressure alerts also differ from blood-pressure measurements.
