There are a few different apps that woodworkers use depending on what type of work they do. For example, many carpenters use the Carpentry Calculator app which helps them estimate how much lumber they need for a project. There are also apps specifically designed for tasks like creating virtual prototypes of furniture pieces or cabinet layouts. Some woodworkers even use augmented reality apps to help them visualize what their finished project will look like. No matter what type of woodworking you do, there's likely an app out there that can help make your job easier.
