For my needs, I have always considered the average bubble level to be acceptable as a casual better than nothing tool. Not that one bubble is truer than another, the tool that holds the bubble is another deal . Just check some of the prices for machinists levels, like starrett , which I believe are more analogous to my turntable needs.
My turntable is suspended , so I am screwed , and shoot across with lasers for a no touch approach. But I still need to find level to aim the laser paths correctly.
I would think any phone would be an upgrade from hardware store stuff, which is generally sold for rough woodworking or pipefitting . When I worked with a level , every hardware store beam level had an "X" by one, of several bubble levels, that wasn't accurate enough to use.
The gyroscopic mechanism in the phone, which does the leveling , is pretty trick. When the mechanical gyroscope was replaced it was by using the fact that electrons travel in a straight line in a vacuum, , so they just shot electrons at a grid in a vacuum tube , and any tilt in the tube could be measured and corrected with improved reliability over a spinning wheel. the tube was quickly reduced in size with the deviation from straight worked out mathematically to compensate for the smaller angles. Now the entire thing is on a chip, that still calculates deviation from straight using a miniscule electron path.
