I've never used Soulver, because I don't have a Mac. I really liked the idea of using text editor style input for a calculator. Being a software developer, I created one to see how this would work. This is my interpretation of the text editor style calculator and I'm trying to found out where I can take this design.

I don't begrudge you bringing this concept to a different platform (kudos for that), but if you arrived at this idea of your on volition, it's a startling coincidence.

Having said that, I'll definitely be sharing a link to your software to all my Linux-user friends. The document-as-a-calculator concept is a fantastic. There's tremendous demand for it as well.

Not terribly startling, no. Anybody that has thought much about advanced text editor features probably has a good chance of thinking to integrate a calculator with a text editor, especially given that spreadsheets are the essentially same idea restricted to a grid. I expect it's been independently re-invented hundreds of times.

Emacs has `calc' which is somewhat similar.

I like the fact one of the features for this app. is: "Addition, subtraction, multiplication and division are all supported".

If this thing ever gets traction, it will be because of this new 'multiplication' feature. Nobody I know uses division, and every calculator out there has some form of addition built-in. Of course, emacs already has it - try `M-x multiply-the-left-number-with-the-right-number-and-return-the-result`.

Personally, I prefer raw elisp to calc.

Available on iPad! I'm getting it now. Not enough of an app to be "killer" but 3 or more such apps would be a fatality! (Takes advantage of form factor to be more usable than the smartphone equivalent, yet is also very useful in a mobile context.)
