Smartwatches from the likes of Apple and Fitbit can export an ECG graph of your heart rate, which can be a huge help when talking to your doctor. The algorithm then gets to work to turn that into an estimation of your heart rate.īut it’s not as accurate as it could be – especially where medical issues are involved.
