This app is meant to make crown molding what it should be: no problem. It provides clear instructions about how to cut each piece for any type of corner, no matter how strange the angle.
It also features a tool to calculate the angles to cut for bullnose corners. A notorious problem in crown molding.
You can also save corners to come back to them later. Do all the measuring and all of the cutting at once, without having to go back to measure every time.
This app also minimizes the amount of saw adjustments you have to make, in order to make cutting as fast of a process as possible. It also provides the option to place the crown face down further minimizing adjustments.
This app will save you time, material, and a whole lot of headache!
