Question: what is the difference between fitbit charge 2 and charge 3?
Answer: The screen is a much bigger difference though, as the display on the Fitbit Charge 3 is 40% larger than the one on the Charge 2. ... The Fitbit Charge 3 has an inductive button for going back a screen or waking the tracker up, but you can depend much more on the touchscreen interface this time around.
