Most of the premium smartwatches and fitness trackers nowadays are equipped with Heart Rate Monitors, but, if you want to take the analysis to the next level, then you need an ECG(electrocardiogram) sensor in it too.

Final Verdict

After reading the features of the above ECG/EKG enabled smartwatches or monitors, it can be fairly said that no single device is superior. But, if you really want to compare, first make a list of your requirements. 

For example, if design and efficiency both are must-haves for you, go for a Cronovo watch. But then again, it does not have FDA approval. If you want a device with FDA approval as well, go for the Apple Watch. 


It is to be noted that non-FDA approved ECG/EKG smartwatches or monitors cannot and should not be used for medical usage. These devices only give you a bird’s eye view of your heart rate activity, but if you are looking for some equipment actually to use the data for health purposes, it is advised to buy only FDA approved devices.
