MathViz 1.0 AppStore link
Before you ask why it's $0.99 and not free - I wanted to see if I could get a FireMonkey paid app approved, and I'm very happy to say that I could. And anyone can, of course!
I will leave it at $0.99 for the next couple of weeks, and anyone that wants to "donate" to a lunch, dinner, party or whatever it turns out to be, can do so in the next couple of weeks. After that it will become free for all.
The link above is live, but it will take up to 24 hours for MathViz to be searchable in the AppStores world wide.
Your purchases of MathViz will go to a couple of things - Apple, the IRS and finally some kind of FireMonkey party of some kind - total volume of paid sales and actual payouts from Apple will determine what will happen.
Now that MathViz is available I will use it for blog fodder, webinar fodder, and I will of course publish the source code.
Thanks everyone in advance for playing and giving feedback!
MathViz 1.0 is powered by TExpressionParser - a flexible and fast expression parser for logical and mathematical functions by Egbert van Nes, with contributions by John Bultena and Ralf Junker. Thanks for Egbert van Nes' explicit permission to use it in a paid app. :)
