No idea about tools although I hope you find something.

Two related suggestions that will change your life:

1. Grunt Fund if you are making decisions about equity
2. Have people estimate the total time for a task, rigidly enforce that every man-hour spent on a project has to be allocated to one of those tasks (including the elusive but vital “oh shit we forgot” task), keep track of the coefficient between the two. It’ll be different for different people sometimes. When estimating a project, have people come up with estimates and then multiply by the coefficient. Be transparent with everyone about this system. It’ll revolutionize your project management life once people get used to it. I tried to find a blog post which explains more detail, but honestly, it’s not complicated, and Google is too shit now to find it.
