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.

Worst application ever!

Try a free web based service for sankeys. This is hopeless, and charged 14.99 for the privilege

Waster of Money

For the $15 I paid for this app, I was expecting something. I got virtually nothing. This app is not worth downloading even for FREE. Sorry devs, apps need features.

it woks efficiently

was able to make my first diagram right away being productive with my time and wasting it.
