Anyone who have can't decide which screenless fitness tracker should buy: between all mejor trackers :
It's completely my own opinion . But whoop is not worth it bcz of the subpriction, polar loop is shit, amazefit helio strap pro is great if the Waist sensor works for normal workouts. I just feel like whoop is a scam, bcz 1st subscription, then their age matrix and strain doesn't have that much scientific backing research, all just mainly gimmick. if there is no subpriction, whoop is right now one of the best. But irregular heart ritham is something only fitbit air have.
My view : if money is not an issue but you hate subscriptions go for Garmin cirqa , but if you are on a budget but want the best value go for fitbit air :
amazefit helio strap pro only makes sense if the waist sensor works for normal workouts not just hyrox. If they do that in future firmware updates then go for it ..
Right now the best value device is fitbit air and Garmin cirqa....i made a detailed table about it. Check.
