Withings Move ECG Watch
Withings' Activité was the first traditional watch to house a phone-friendly activity tracker inside. Their Move ECG continues this tradition, building on the former's feature set with a potentially life-saving feature. Like the Apple Watch Series 4, it has electrodes in the case that let you take electrocardiograms on-demand, using nothing but your fingers. In addition to letting you keep an eye out for heart issues like AFib, it also tracks your steps — with a sub-dial readout — calories burned, distance, workout routes, elevation, and sleep, syncing the data to the app of your choice. Available with a white or black dial, with interchangeable straps.
