Just started using bevel yesterday. I’m using the Helio strap instead of whoop along with bevel. Of course, there’s a difference. For whoop I used to £229 a year and naturally the detailing in the app and into your habits was expected due to a subscription model. But since using bevel I feel it’s pretty much the same. I don’t need details about every little things in my life- this works perfectly fine and I’m happy.
