I largely do the same, but I also track expenses mostly to understand our spending, not control it. I use Tiller to dump our expenses into a spreadsheet and then assign them relevant categories. I then review spending trends and if something looks off, and my wife and I discuss options to optimize it.

For example, I noticed our restaurant spending was going up, so we set a goal to try cooking new foods and that helped. It didn't feel like we were sacrificing, just adjusting our lifestyle a bit to be more in line with our goals.
