The main improvement in my daily routine as a result of using a smartwatch is that I no longer miss calls or important messages. I'm the type that wears baggy pants, and often times I won't feel the phone vibrating in my loose pocket, causing me to only notice that I have calls much later. Having a smartwatch to alert me whenever I receive any incoming calls and messages has fixed that problem.
As someone who goes for running activities regularly, a smartwatch is also a good way of tracking my workout. Prior to getting my smartwatch, I relied on a sports armband to support my my phone while I run. Whenever I wanted to check my progress, I had to tilt my head to the side to check what was on my phone screen.
