Amazfit Active 2 Sport Smart Watch Fitness Tracker for Android and iPhone, 44mm, 10 Day Battery, Water Resistant, GPS Maps, Sleep Monitor, 160+ Workout Modes, 400 Face Styles, Silicone Strap, Free App

I've been using an Amazfit Active 2 for about a year since they launched, no complaints, it has a good app that creates daily workout options for you, calorie tracking, trophies, etc., I spend way too much time in it, lol. It's on sale currently for ~20% off, $81 is kind of a steal IMO. I actually picked up a 2nd one just in case something happened with mine. I generally have to charge it about once a week.
