In addition to a broad selection of drawing tools, the ArtStudio Lite app also includes customizable brushstroke size settings, a selection of pre-drawn geometric shapes to add to images, symmetric or mirrored drawing, layers and a multitude of photo editing tools such as forty filters and adjustable brightness/exposure/shadow settings. The latest version available on the App Store is compatible with the iPhone 5 and includes sixteen different tools, including select, paint fill, eraser, heal, smudge, eyedropper, dodge/burn and one-hundred-and-fifty different wet and dry paint brushes. While it is also available for Android users, the app was originally designed to run on iOS devices, meaning that it runs much more smoothly on Apple phones and tablets. The self-proclaimed “most comprehensive sketching, painting and photo editing tool in the App Store” is the perfect program for digital artists wishing to draw on their iPhones, iPods or iPads. Photoshop Sketch is available on both the Google Play Store and on the App Store.
