I'm a freelance 3D/motion designer in Bern, and for years my honest answer was: more than I wanted to admit.
Not the big blocks those I remembered. It was the ten minutes of client email, the quick After Effects fix before dinner, the revision on a Friday evening. By Sunday I'd be scrolling file timestamps trying to reconstruct my own week, and all the small stuff was already gone.
Finally a time tracker that gets out of my way, the auto pause when I step away actually works and the local Mail scanning picked up a client reply I would've totally missed. Worth the one-time price.
@upton_louisaΒ Thank you so much for your kind review!
