The shapes you draw are automatically closed and straightened, all primitive shapes are instantly recognized. The lines you draw between shapes are automatically turned into connections thanks to our shape recognition algorithms.


Some diagrams require more advanced objects. Grafio provides hundreds of shapes you could easily drag in from the library. You could also insert images from your Camera Roll as shapes and connect them to your other shapes.


Recording audio notes to your shapes could be a way for you to collect your thoughts or you can use this feature for something more creative, like taking an interview or recording your riffs for example.


We developed a non-intrusive interface that will get you straight to the point. All advanced features you might need are also there hidden beneath the surface. To have all that power on your iOS Device at your fingertips is truly amazing!
