From the developer:
With CalliPro you can create Arabic calligraphy artwork that matches that of top calligraphers. It lets you insert any Aya from Quran with its search capability. You can create designs with different sizes, save designs and open them later, and work on multiple designs at the same time. The tool allows you to change the color and the width of the text outline, edit elements, make the background transparent, add a background image, and more.
