You may have seen many people who like to roughly create a sketch of something that they want to create. No matter who it may be, for example, it may be a painter, architect, logo designer, fashion designer or may be any mobile app development services. Almost every other person draws out a rough sketch before creating their final product. Therefore, you need to draw out a rough sketch (known as a prototype in app development terminology) of your app before you finally create or launch one. Did you ever think about a prototype as such an impotent thing for your app?
