Comment on Calca iOS - Mathematical text editor for engineers

Glad to see Soulver [1] has some competition.

I absolutely love Soulver, but I think it's trying to achieve a subtly different aim. Soulver is a lot more focused, and definitely more a calculator (albeit one re-designed for the modern era) than a text editor.

What I'd really like to see is something like this, but with in-line typesetting. Similar to the Markdown editors where when the line is active and you're editing it you see the raw text, but when you move off to another line you see the typeset mathematics. Because at the moment, it's just so much quicker and easier to think with pen and paper when you can actually write and read correct notation, rather than a monospaced-ASCII-fascimile...

There is another similar app called MathPad, a Mac app first released twenty years ago:

Soulver groks magnitudes of bits and bytes, and carries units or denominations over, making it invaluable for quick scalability planning or bandwidth estimates and sharing the templates with teams via Dropbox. Love this tool.
