Sketch by Connie Sketch by Sohan PROS Help you draw straight lines, if you can’t draw straight lines like me, then this app would be your life saver You don’t have to sketch everything, you can make use of the furniture library and texture You can group your lines/sketches into different layers, so that it is easier to erase something and faster to do alternative layout (pretty similar to the layer function in Photoshop) CONS There are no scale ruler or any scale tool, you have to rely on an accurate base image or the grid You have to use apple pencil and have to pay for the app You have to search for suitable libraries
