Hello @Riehle and welcome to the Community. Join the crowd. Floor tracking has always been part of the Charge family of trackers. I didn't bookmark the page, but I saw a YouTube video that showed a technician replacing some part (can't remember which part). I think that the ECG and EDA sensors take up space and that Fitbit couldn't put in the altimeter and keep the "Charge" tracker size. Just a fellow user with an opinion. No insider knowledge.
