Genuine question for the builders and deep-work people here.

I've used basically every productivity tracker: RescueTime, screen time, Toggl, the lot. And I keep hitting the same problem: they tell me I spent 8 hours "working," but they have no idea whether I was actually locked in or just bouncing between Slack, email, and 14 browser tabs pretending to research.

8 hours on a Mac 8 hours of work. We all know this. But almost no tool measures the difference.

So I've spent the last few months building one. It tracks focus blocks (sustained time in one app) and drift moments (rapid switching that signals you've lost the thread) and gives you an honest work rate per session, not just a minute count.
