Has anyone tried Motion? Thoughts?

Keep getting ads for Motion since reading Deep Work by Cal Newport. Wondering if anyone's tried it and has any thoughts?

I'm aware it's pretty expensive but the page is very clever and doesn't show you how much - if anyone in the UK could tell me exactly how much every month or year that would be great. And just any other thoughts on it. It looks interesting and might be able to help my focus/productivity/attention issues... but I'm not sure.

Thank you! If anyone has any similar apps feel free to recommend them too.
