Anybody have an Apple Watch or a Fitbit? I'm looking into getting a watch simply to track my workouts. Since Series 4 of the Apple Watch is discontinued, I'm not ready to put down $400 on an Apple Watch for just exercise. I'll never use it to check or reply to text messages, use Apple Pay, etc. However, the Series 3 watch is around $200 and appears to offer more of what I'm looking for (also, would buy GPS model, not GPS + Cellular). So the price between a Fitbit Charger 4 and Apple Watch Series 3 is about $50. Also, the Fitbit has sleep tracking, which is a feature I'm curious about. Anybody have any feedback on either/both?
