Flowchart Designer 3 4+

I needed to create a decision tree to analyze a situation. I checked the App Store for apps to create org charts and flow charts. There are so many! It's hard to know which to choose.
I read a few reviews and descriptions, and decided to try Flowchart Designer 3.
The app opens with a tutorial on how to start creating charts. The UI is straightforward. If you have used any kind of drawing app on the Mac, you will be familiar with it.
The feature set in the free version is pretty limited, but that's OK. There are enough features to create basic flowcharts, org charts - and decision trees. People who complain that it's too limited have to remember that it's free. For a few more dollars you can unlock more features.
I was able to get up to speed quickly, develop the decision tree, and submit it to the team for review. If I continue to use Flowchart Designer 3, I will probably pay to unlock the additional features.

There are a few free flow chart and design apps for the iPad, and while they do the job for me, I was thrilled to discover a Mac-compatible alternative. That moment was the best of my life. This program is a pretty straightforward chart or flowchart, and I can use it on my iPad, iPhone, and Mac mini. It doesn't matter what approach to mind mapping you're trying to adopt. Dad has all the fundamental features necessary for easily producing a professional-looking flowchart. Obviously, I shelled out for the full version, and I couldn't be happier; please keep improving flow chart designer; it's a fantastic tool. ~ Robert Smith, policy Manager

This is a very powerful and intuitive tool for making a wide variety of great looking flow charts. The customization options are complete and easily accessible. Alignment, snap, line styles, colors, sizing - it’s all there. The only problem I’ve found is with text. For every object type including the text tool itself, the text alignment option (left, right, center, justify) is broken. If you ever de-center text you can never center it again because the center option does not work. Thankfully, center is the default so all text objects are initially centered.

The fee for purchasing the full set of shapes is well worth the $7.99 one-time price. I hope the text alignment issue gets fixed, then this app will be perfect.
