[Sponsor] Illumipad's Multi Calc 6×4

Sometimes you come across such a simple yet clever app that it changes the way you do the most basic tasks. I’ve relied on the calculator widget on my Mac thousands of times to get quick answers to basic analysis questions. It’s much easier to press the F4 button than launch a spreadsheet. However you quickly run into the limitations of a simple calculator. Multi Calc 6×4 is a clever idea of having up to six linked calculators available on your desk at any time. From a work-flow point of view it sits between a spreadsheet and a calculator. You can do complex multi-step calculations without learning a new UI.

Every result from a calculator can be dragged to another with just press-and-hold touch. No more need for “memory” functions. This is the sort of improvement in a basic, everyday tool that only a large screen and touch interface can enable.

    Check out Soulver for a different approach to the same problem. Both apps have good ideas.

    Did something happen to this app? 

    I purchased it back when Asymco posted about it and now it has disappeared from the app store. 

    AND the copy I had installed on my iPad has stopped working (launch, then immediately close). I uninstalled the app, then discovered there is no reinstall option, the app and the publisher have just vanished for me. 

    Perhaps it has something to do with my recent upgrade to iOS 5.

    Anybody have any info on what happened to Multi Calc 6×4 for iPad?
