Every time I found myself needing something hyper-accurate for woodworking and there did not seem to be a common solution I learned that the design was wrong for wood.
Martin makes a very nice compound miter solution for their saws that is accurate to .01 degrees. ?Depending on how long your edges that is probably not enough to cut perfect parts.
If you want to machine a material more accurately than that then you get into metal working machinery and maybe even a jig borer. ?Mac Campshure told me about the Moore Jig Grinder/borer and I read a couple books about Metrology trying to learn what tolerance was workable in a woodshop. ?My goal in my shop when making tilt and turn windows was plus or minus .1mm. ?This is very hard to achieve and I rarely did but that was the goal. ?
I once hired a shop to make Plywood boxes for an art museum. ?He showed me how the beveled joints just had to be close, not perfect, and how it was a simple mater to run the edge of screwdriver shaft along the seam and close the gaps. ?Knowing how to work with the material made the finished product possible. ?

Well at the end of the day, the $1,000 starrett tool is the only solution, damn!

I have a couple of those digital level gizmos too. I used one for setting blade tilt angle on a cabinet saw, and it was an improvement over the indicator on the saw itself. If one needs super precise measurements it is not likely to be sufficient. The base is narrow and is plastic, so manufacturing tolerances limit them.
They are robust. I saw one get launched across a shop when the operator turned the saw on with the device still on the blade. The case is a bit chewed up, but it still works.
