My colleague uses 2 kitchen timers to track daily progress on his two main projects. I was inspired by this to create an open source app but for yearly goals - https://github.com/anyg-me/goals-tracker
He has two main projects - A & B. Currently A takes up 80% of his time and B takes up 20%. He uses the timers to track time on each project with the goal of transitioning to 80% on B.
