Ratings and Reviews

Not so great


They are there to make you shop & pay to upgrade . The app looks entrapping & not so user friendly .

Wish i could lock the 3d


Quality is ok. Somehow my drawings come up as 3d images and when I try to move around the drawing, it rotates it. It is pretty clear though and drawings are rendered pretty fast
