Calca App

Calca App is an Android app that helps you draw any image you have stored on your device. Basically, this app works like a camera lucida, although instead of projecting the image, it superimposes it when you open your camera. This way, you can use Calca App to practice your art, for example, or to transfer something you've drawn digitally to paper.

To use Calca App, it's best to have a physical support for your device so it doesn't move and you can keep your hands free.

Calca App allows you to choose an image from the app's library, the Internet, or your own gallery. You can also take a photo on the spot; as long as it's an image, you can use it, no matter whether it's a sketch, a screenshot, or a photo of the skyline. The only limit is your own imagination; with Calca App, you can do all the rest.

Using Calca App is very simple: place your Android device so it's pointing at the paper you want to draw on. Select the image you want to trace, then adjust its position and transparency. After that, all you have to do is draw while looking at your Android's screen. Calca App also works on walls, blackboards, and more.
