Maybe it's not necessary but, I always zeroed the Wixey on the blade. The levelness of the table is not consequential. But, I like to start with the table at 90 to the blade.
For me, the advantages of the Clinometer are:
1. It's Free
2. It's Accurate
3. Being on the phone it's a. handy b. it's rechargeable and, c. it's easier to read at any angle.
It won't reaplace my old standbys for angle finding but it's another tool in the arsenal.
And, did I mention...IT'S FREE.
Or, for $0.99, you can upgrade the software to a paid version that supports differential angle measurements.
The accuracy that you get will depend on your device hardware, so I wouldn't expect everyone to get the same results. I haven't yet tested measurement accuracy on mine.
I found that I have exactly one surface on my Android phone case that is nice and flat. But it happens to be the left-side edge, which is probably the most useful one for me.
