I bought a charge 4 a few years ago. I don't work out a lot so I mainly use it for the sleep stats, heart rate etc. I'm wondering are the newer fitbits more accurate or do they give you more information? I'm wondering if it's worth going for a newer fitbit or would I be better off going for something more smartwatch style or maybe a whoop (although the monthly fees are very offputting)
