Professional drawing tool to create Sankey Diagrams. These diagrams show flows, where the width is proportional to the rate of flow. The diagrams can be created interactively, adding flow sources and sinks, moving nodes and flows around, editing colors, and more. The diagrams can be exported as a .PDF or .PNG, shared by email, messaging, saved to the Camera Roll, or shared to FaceBook or Twitter. A .SNK file version of your diagram can be shared by email with other Sankey Diagram app users, who will be able to load and edit the diagram. You can also create a diagram by importing a .CSV file from an email attachment or iCloud. The diagram is automatically created from the data in the spreadsheet. Edit diagrams on any of your devices using iCloud.

Not ready for prime time

Update, 1/11/15

This is still quite buggy.

With the latest version, when I create a node, there is no window to change its name, color etc. So, now I can have multiple nodes called "Node 1"

Don't give up. The app has potential.

Original rating:

I've been waiting for a Sankey app for years. I'm still waiting for one that works.

First, the only units that seem to be allowed are the default units called "flow units". Can't enter dollars or gallons or pounds or whatever.

Second, the app crashed 3 times during the first hour.

Third, I left the app for a moment and when I returned, the only version of my diagram was an hour old. All the work I did during the previous hour was gone.

I would like my money back, please.
