The Miter Saw Settings app will save you time and money by preventing improper cuts when installing crown molding. The cost of the Miter Saw Settings app is very little compared to the cost of scrap molding because it was cut wrong. The Miter Saw Settings app will accurately calculate the miter and bevel settings for the corner angle you enter. The app has clear examples of how to set the saw and place the stock molding on it to make the proper cut. There are examples for inside and outside corners on a flat ceiling and for corners turning up or turning down for cathedral and vaulted ceilings. Both double and single bevel saws are covered by the examples. All the information entered is saved if the device goes into standby, the user switches to another app or the device is turned off. The Miter Saw Settings app is a valuable tool when used with a compound miter saw to cut crown molding.
