This is a free application that offers advanced features, but some of these features require a pro license that can be purchased in-app. When you purchase a single license, it will activate all devices associated with your Google account.
Some of the advanced features that require a pro license include a high performance paint engine that is GPU accelerated, the ability to work on canvases up to 6144x6144 with 50 layers, and stylus pressure support. There is also pressure simulation for touches, which allows for a more realistic drawing experience.
The application offers over 100 brushes and tools, including a smudge tool and gradient fill. You can even create custom brushes from imported images. Other features include selection and selection masks, layer clipping masks, and 10 layer filters such as HSV adjust, brightness and saturation, and color curves. The user interface is inspired by material design and is fast, fluid, intuitive, and accessible.
ArtFlow is designed to be a universal art studio type application for Android™, allowing you to paint, sketch, and draw with ease. It aims to replace your physical sketchpad and offers features such as NVIDIA DirectStylus support and palm rejection to prevent accidental zooming and panning while drawing.
The application showcases artwork from various artists, including Oleg Stepanko, Miguel Alvarado, and David Rivera. The unlicensed version of the application has some limitations, including access to only 20 basic tools, 3 layers, and a limited undo function. It also does not allow for PSD export.
