This app called Easy Draw helps you to paint easily with the help of AR technology. One of the main steps in painting is drawing the initial lines of the model. With this app, you can easily scan the model you want to paint and then the app will give you the main lines in which the model is and you need to draw them. Once you have those lines, you can easily hold them on your paper and adjust them to the right size, and then you can start drawing the pattern on the paper based on those lines.
