ECGMost wearable smartwatches today have an optical heart rate sensor, but the ECG goes one step further by measuring heart health. It measures your heartbeat pattern to identify any abnormalities, which might be indicators of heart disorders. While this is never as accurate or reliable as the ECG you can get at a hospital, this feature has helped a lot of people identify heart disorders early on.
GPSInitial smartwatches and fitness bands relied on your smartphone for location data. That meant you’d have to carry your phone outside to track your runs and cycling. However, any modern smartwatch should come with its own GPS sensor to keep track of your location independent of your smartphone. This makes them more capable as dedicated wearables rather than smartphone companions.
VO2 MaxAnother feature that was only found in high end watches earlier, VO2 Max is gradually making its way to popular devices. It reflects the aerobic physical fitness of the individual and is an important determinant of their endurance capacity during prolonged exercise – the higher, the better. Smartwatches measure this by combining your heart rate data with your pace. Individuals with higher VO2 max run maintain a lower heart rate at the same pace as compared to someone with a lower VO2 max value.
Wireless chargingCharging a smartwatch or any kind of wearable often required complicated proprietary chargers and mechanisms. With wireless charging making its way to modern smartwatches, it tackles both problems at once. It makes it super easy to just place the watch on a charging mat to start charging, while also making it easy for one watch’s charger to be used by another.
Screen protectionKeeping a wristwatch safe from absolutely any collisions is not always possible. While this almost spelt certain doom at one point of time, today modern smartwatches come with their own screen protection technology like Gorilla Glass or Sapphire Glass screens. Not only do they improve durability, they are also scratch resistant which helps maintain the watch in brand new condition for longer.
