As the name suggests, this app enables you to paint freehand using a selection of brushes, colors and other tools. However, Sketch is more than just a painting app. It also enables you to connect with like-minded creatives, so you can follow artists and see their work updating. Once you’re done sketching the image on your iPad, you can upload to the Sketch community, or continue working on the image in Photoshop CC. You can also bring in brushes made with Adobe Brush, and for those who can’t paint, there’s an option to overlay images so you can trace over a photo. Sketch is compatible with Adobe’s pen and ruler hardware, Ink and Slide, but you can get great results with your finger.
