Ten minutes in Excel to do a simple linear interpolation?
Something sounds wrong.
Perhaps you could publish your spreadsheet and one of us could look
at what is taking so long.

The last time I actually did something with extrapolation it was using
matlab, just because I like the graphs it produces more than
excel/open-office... the last time I was working with concentration
data though, I probably used excel/open-office.
The easiest way to build cross-platform apps is to do it in
HTML/Javascript... then in iPhone/Android you just drop a webKit
object in and load up your HTML. If you're making an app, I would say
you'd start entering the concentration and absorbtion/transmission
value of a standard, then allow users to keep adding more standards
(to build the "standard curve")... then allow then to enter the
unknown values.
There's some pretty nice Javascript graphing libraries available for
free on the web, I'm not sure of the names, but we're using one for
the open spectrometer data viewer which included zooming in/out, etc.
