Heads above the others !
I have/ had a few apps along this line and they were either mediocre or good. The reason being is you were limited in the final finished drawing due to the fact that there were as a rule no shapes that were provided to allow you to be more creative. Well look no further this app has LOTS of shapes to choose from, the colours REALLY are vibrant, almost glowing ! I started with the free version ( and this is my ONLY peeve with this app) and the pop up ads were NEVER-ENDING and ANNOYING to no end ! I decided to go for the full version ( very reasonable price as well ) and I was NOT disappointed ! * Note to the developers * PLEASE change the icon as it really doesn't do justice to the beauty of this app ! Rather ( and please forgive me for this comment !) it actually makes it look more like an app for small children. I would definitely recommend this app if you like this type of line drawing!
