Is a smart watch touch screen?
Most modern smartwatches are operated via a touchscreen, and rely on mobile apps that run on a connected device (such as a smartphone) in order to provide core functions. With most connected smartwatches, you can still make calls, send texts and receive app notifications, even if your phone is turned off or left at home.
Can a smartwatch replace a phone?
While not a complete replacement, a smart watch can certainly help with your everyday online ventures, saving you from being stuck on your phone and giving you more precious time to live your life out and about. A study by the prestigious american college of cardiology (acc) found that overall, smart watches are very sensitive and specific in detecting afib. This is particularly useful to patients who already have symptoms of afib and want to monitor their heart rates.
