A:AnswerI recently bought this for my sister for this purpose. She seems to love it. Can't say specifically pros/cons, but I haven't heard any complaints.
A:AnswerJust call the customer service number to assist you in price matching the item. I don’t think there is a way to complete this online without calling.
A:AnswerThe GPS version does not require you to pick a carrier. The GPS version must have a bluetooth connection to your phone to allow you make calls or text from your watch. For example, if you were to leave your phone at home when you leave for work. You would not be able to make calls or text from the watch.
A:AnswerThe built-in GPS works independently of your iPhone for distance, pace, and route mapping in workouts. This Apple Watch comes with a Sport Band. 40mm Sports Bands can accommodate 130-200mm wrists. 44mm Sport Bands can accommodate 140-210mm wrists. Other bands and sizes sold separately.
A:AnswerNot that I can tell other than maybe being more sensitive to movement. I noticed with my series 3 the calorie tracking seemed a little bit off like maybe it wasn’t recording everything correctly.
A:AnswerI know it will work with iPhone 7 because that is what I used for mine. I don’t know about the iPhone 6, but I think it depends more on how up to date the iPhone operating system is.
