The Graphio Lite 3 app is a handy app that makes drawing professional diagrams—even complicated ones—easy. With the shape-recognition feature, the app instantly converts hand-drawn doodles into perfectly drawn shapes, and users can quickly connect those shapes with arrows simply by swiping across the screen from one shape to the other. The best part for anyone who’s ever labored over how to precisely arrange diagram nodes relative to one another is that once shapes are connected, those connections are maintained (and automatically adjusted) if users subsequently change the position of any individual shape. The app also includes functionalities such as stencils for more complex shapes, text, and even audio notes. The free Lite version is very usable, though if users desire additional export options, watermark-free diagrams, or unlimited documents, they should consider purchasing the full version.
