FoCo - Focus Companion

FoCo - Focus Companion とは？

A tiny always-on-top widget for macOS that protects one thing: the task you declared when you started. Blocking websites doesn't work when Facebook, ClickUp and Google Workspace are your tools. The real problem is different — it is the cost of catching a stray thought. You're deep in a task, something unrelated surfaces, you switch to another app to write it down, and on the way there the original task dies. That round trip costs about two minutes and a full context switch.
