Smooth

I cannot believe how smoothly I can move around the boxes and the flows follow. Makes it intuitive to arrange the diagram. The essential feature however, is ability to export to PDF. That makes the app practical for my use.

Not ready for prime time

Update 12/8/24, This app hasn’t been updated for 4 years. Evidently, it hasn’t kept up with iOS updates so it doesn’t work any more. Pity…. I wish somebody would update it.

Update, 12/22/18

Too bad the developers have given up on this little app. It has great potential to be a useful app for expressing complicated flows in an easy to understand format.

The bugs I reported in 2015 seem to have been fixed so I upped the rating again.

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.

Good idea but...

The idea is great and a couple of examples are available. 30% of the screen is covered with the library menu which reduce the working surface to a very small area. Moving elements around doesn‘t work properly and formatting is complicated. Every element needs to be marked and then a menu to be opened.
Good basis but needs plenty of improvements regarding user friendliness.

funktioniert prima..

Ich brauchte allerdings eine kurze zeit, um die Bedienung zu verstehen. Den ersten Kasten erstellt man durch besonders langes drücken auf die freie Fläche. Einen Flow bekommt man, wenn man 2 Kästen gedrückt hält.
Bewegen, indem man sofort nach touch zieht.

super!

Für mich die beste App zum Erstellen von vernünftigen Diagrammen.
