After we complete our Design Process we start to sketch all the interfaces that the users will see, whether it is an app or a website, a basic layout in the Sketch App provides the customers with a solid idea about how the product will turn out.
We primarily use Sketch App and Adobe Illustrator to do the wire framing and sketching our products. After the initial sketching we will get feedback from our customers by sharing screens on Marvel or Invision. These tools provides the user with the ability to comment on a single UI elements so that we can work collaboratively to make the user interface.
Thank you for your interest, we will get back to you as soon as possible. :)
