Alph Comes to the iPad!

[Craig Morris]

Version 1.3 of Alph is now a "Universal" app that will run natively on
either the iPhone/iPod Touch or the iPad. The extra screen real estate
on the iPad allows the information flow diagram to always be visible,
with other windows opening over top of it. The functionality is
identical on both devices, but the iPad definitely is nicer to work
on.

This version also introduces a function solver tool which will use the
Brent (single equation) or Broyden (multiple equations) methods to
alter its outputs until the input formulas equate to zero. This allows
the solution of both simple adjust functions and complex multiple
recycle problems to be automated.

The base version of Alph now includes the tower tool, compounds C1-
nC10, iC4, iC5, N2, CO2, H2S and water, but it now costs $19.99 or
your local currency equivalent. Alph Jr continues as a free
application with all tools, but limited to just C1-nC10. Having the
base version of Alph less capable than Alph Jr. just didn't seem to
make sense.

The compound options have also been consolidated into larger groups
and an Alph Professional option in the Alph Store will upgrade Alph to
have all available features.

Other changes include:

Interface changes - the Information Flow Diagram takes on a more
central role.
Formula enhancements - added trig functions, max and min functions and
even an if and a not function.
Polytropic Efficiency is now calculated by the compressor/expander
tool.
And of course numerous miscellaneous fixes
