Camunda is a simple app for creating technical diagrams. You can easily drag and drop any point and it will automatically create lines and arrows for you. You can also choose from different types of points which can be helpful, for example, for highlighting when a user receives an email from Intercom. Camunda allows exporting to SVG that makes it easy to colour trackable points in Sketch.

The creation of interaction flows is a big part of our process as digital product designers. After many iterations we now have a mind-bending fast way to do all of this in 💎Sketch.

Frighteningly fast user flows, content maps, screen annotations, and more.
