Looking for experiences with Whoop Fitness Band and it's companion app

Hey all!

I'm looking at getting a wearable specific to fitness that I can set and forget. I have an apple watch and, it's fine, but kinda uncomfortable to wear for bed, the battery is a bother and, I'm not sure it's complexity helps with my physical goals. I say all this just to avoid someone suggesting the Apple Watch as an alternative. It's good at what it does, it just doesn't fit my requirements.

That said, has anyone had any experience of Whoop? I've heard about it several times, a wearable that is just that, no screen, only a haptic output to wake you up and that's it. All the magic happens on one's phone tracking sleep, strain, and rest. It's usp is optimizingrest and excersise specific to you.

My question is, is the app accessible? I've just been having a poke about in it where you can order a band but, without a band, I don't think I can test out the meat of it.

Thank you.
