Samsung makes a smart watch, too. I believe it does most, if not all, the same things as an Apple Watch. It has a heart monitor, will contact emergency numbers, you can answer calls and texts, and control music.
I have an Apple Watch and iPhone, and love the ability to answer a call (then ask the person to hang on while I go get my phone), quickly see incoming texts, find my phone, and check my heart rate. If you’re comfortable with your Samsung, though, you may not appreciate the learning curve needed to start using another brand device.
