I've had my Apple Watch since launch day and have loved it. It's definitely motivated me to exercise and be active more than I already was. I do a lot of fitness classes at the gym my company offers and have found that I love having heart rate data. However, for activities like circuit training or non-running/biking types of things, the HR data is spotty (which gets frustrating quickly). So... I bought a Polar H7. I guess I didn't know what I was missing until Apple showed me the feature but didn't implement it in a fully usable manner. The H7 is rock solid and feeds data consistently and constantly during my workouts now. Plus, I can use third party apps (like Runtastic Gold) and get HR data fed into the activity feed (which lets me overlay heart rate data over a map, pace, elevation, you name it). I love it. I still like having the Watch for seeing the data on my wrist during the workout but this strap (at least for now) is a required fitness accessory for me. Anyone else follow a similar path?
