I have seen some iPad art works on the internet, and I have always wondered how people were able to create the beautiful effects on iPad, like water color, shades of painting, and delicate color changes. I started exploring some of the drawing apps available. It is amazing to see the kinds of drawing capabilities you can have with a nice drawing app. Today I found SketchBook Pro is free for limited time. This is a good opportunity to try and learn what capability you can have if you are drawing or creating art on tablets. 
There are many functions that help freely create the art you want. First are the tool selections. There are so many options: pen, pencil, brush, … for pencil, you can choose from 4H to 9B. You can choose drawing line width, transparency level, and texture, like with wavy or splashing effects. You can also choose lines made of different shapes, like flowers, leaves, circles.
There are stamps for you to use: like butterfly, bee, man running, kid playing swing.
The color wheel makes choosing color easy. You can also pick a color from an existing picture to make the perfect match.
There is an option that adds symmetric lines of whatever you draw.
Using the timeline feature, you can even create animation effects.
The layer function makes adding and taking parts of drawing easy. If you already have a picture you like, but want to experiment adding some elements, instead of drawing on the picture directly, you can add a layer and work on that layer. This way if you don’t like what you added, you can just take that layer off.
I also like the option to save your drawing on iCloud. We all know how much space pictures take. You can draw many pictures without worrying about running out of space on your device.
I am still exploring the functions of the app. SketchBook has separate apps for iPhone and iPad. The first App Store button below is for iPad app, and the 2nd is for iPhone app. It is also available for Android on Google Play and Amazon App Store.
If you would like to check it out or purchase it, please use the App Store link provided below. The cost is the same to you, but iGameMom gets a small percentage. Thanks for your support! Note: The link works for all countries.
