When I bought mine, it was a 1 time purchase. I am grandfathered in on that and would never pay a monthly, because I am opposed to gravy train monthlies just on principle. That being said
reliability/build quality is absolutely solid, Neither I nor any other whoop users that I personally know have had an issue
Opening the app is pretty easy, it’s right there on your phone. There’s also a web version with even more stuff.
It syncs with trainingpeaks, to what end I don’t know because I didn’t care enough to examine it
I think Whoop has very limited time to get itself sold. People will not want to wear a strap when the same functionality should be in a device that also does other stuff (apple watch etc).
The monthly cost, in perpetuity is crazy. It was touted in the fitness press as a less expensive way to get a whoop, as if the writers didn’t have a calculator.
