A free app for Android, by BRB Apps.
Sketch Copy is an image-tracing application that lets you trace any picture you take with your phone’s camera. This means you can use your phone’s screen to draw whatever you want. It’s a great tool for artists who want to practice drawing.
This app will not display the image on the page, but it will let you draw it as if you were drawing on a piece of paper. You can also change the size of the image and use different colors and styles to draw your picture.
This app has a built-in image viewer so you can view and compare your drawings. You can also use this app to make a screenshot of what you drew.
