I have a lot of walls that slant inward. To measure the angles at which they slant inwards, I used an app that looks like:

Was this the correct tool? Assuming it was, do I need to make sure I get the Y value to be as close to 0 as possible before taking the reading of the X value (which ultimately gives me the wall angle)?

You could maybe use the phone App tool but you would still have to translate the angle reading into lines on the pieces of wood. A far better tool was invented long long ago that direct measures the angle and then allows for direct transfer to the wood. It is called a carpenters bevel or a bevel square.
