This app allows you to select an image from your photo gallery or take a picture with your camera, and will overlay a grid which can be adjusted in size and transparency, as well as color.

The grid serves as a guideline so that you can sketch it respecting the proportions of the original image.

How to use it?

- Load from your device's gallery or take a photo
- Adjust the size, the opacity and the colour of the grid
- Save the image to the photo gallery
- Copy square by square the image to the paper
