With the improvement in the quality of Android screens, the drawing and painting apps take on more relevance giving greater advantage to being able to use our own fingers to make some quick sketches if we have some creativity that allows us to make all kinds of lines, gradients or shapes.
The four apps that you will find below will take you to your phone or tablet the ability to create beautiful artistic recreations to teach your talents or they will help you to practice certain techniques of what today is called digital painting. A whole new artistic expression that becomes a reef so that artists can demonstrate how to innovate and surprise. What are you waiting for to improve your creativity?
Autodesk SketchBook

This app is without a doubt the best that exists in the Play Store. It has recently been updated, bringing some improvement or another, replacing previous versions and with a payment model within the application to be able to activate its best features such as layers, more tools, better brushes, gradients and much more.
Among its notable features is the ability to zoom in 2500%, 10 pixels to select (pencils, markers, etc.) and the ability to link the app with the Dropbox account to save artistic projects. The Pro version is the one that takes all the game out of this app, since it comes with: 100 different brushes, full control over layers with 18 types of mode, Copic Color, lasso tool and magic wand, and tools for gradient.
A great app that is already in its free version offers the necessary tools to draw, having the Pro version to get the most out of your tablet.
Art Flow

ArtFlow stands dealing with the aforementioned, since we are facing another great app for drawing and illustration. The app is intuitive and offers among other things, more than 70 pixels and tools with the possibility of creating up to 16 layers with the capacity of history to be able to eliminate the mistakes that have been made while illustrating.
The canvases can arrive at a size of 4090 x 4090, and you have the app for free from the Play Store and with the Pro option with more features. An app that rivals Autodesk's and with which you can create noteworthy illustrations and then launch them on sites like DeviantArt or Behance.
Painter Mobile

It comes from Corel, with the endorsement that this means. You can make sketches to even take them to the Corel Painter app on your computer desktop.
Among the basic main features are effects, symmetrical drawing, canvas rotation by gesture and the ability to create up to 20 layers. You have it for free for Android, but like the other two you can access more features through the Pro version, which even adds the ability to save the illustrations in PSD or PNG format.
Another great app that can't be missing from your Android if you have a talent for drawing.
Bamboo Paper

Wacom Bamboo Paper does not have all the "pro" features of the previous 3 but it has a great advantage, since comes endorsed by Wacom, the best graphic tablet creator company, and hence the natural touch of drawing with the touch of your fingers can become one of the best experiences on Android.
Bamboo Paper it's more of a kind of notebook, but that has a great virtue for drawing. It does not have all the features of the previous ones, but it has all the basic tools to be able to make great drawings with a little creativity on the part of the user.
If you want to do a few quick sketches is the perfect app for this task. It is available for free with premium features, although yes, it can only be installed on tablets.
