Draw like Da Vinci and Dürer with the help of the grid.
- Take a picture (or use one from your photo-roll), scale it, rotate it, pan it.
- Add a grid to it. Pan and scale the grid.
- Save the project when finished.
When ready to draw, load the project and press the start button. A counter will keep track of the time you spend on the project.
The bigger the phone, the better.
While drawing, the screen saver is suspended, so watch your battery.
