Review on Blackview Smart Watch: GPS Running Watches for Men, Women, and Kids – Fitness Tracker with Heart Rate Monitor, 5ATM Waterproof. Compatible with iPhone & Android Phones. by Adam Walsh

This watch works fine as a regular watch but the options are different than I expected. I wanted a watch that could easily track runs (start and stop) and change songs along the way. It can do it, but the way it does it isn't how I'd like it to (fast song skipping/pausing, automatic mileage tracking - it detects when you start running but requires you to do so stay in place for long as the GPS won't catch up). It would be better if it could take the GPS from my phone or store songs on it so I don't have to carry my phone with me. I ran it simultaneously with the run tracker app on my phone and it showed a difference in distance of 0.2 miles (3.1 total) for each of the 3 trials I attempted.
