Mariner Software has released its first iPhone and iPod touch
application: Mariner Calc
( It’s now
available for US$9.99 at the Apple App Store.

In development for more than a year, Mariner Calc takes advantage of
almost two decades of spreadsheet experience on the Mac, according to
Michael Wray, president of Mariner Software. It also introduces the
ability to view and edit native Microsoft files (.xls format Excel 97
and up) on the iPhone.

Mariner Calc includes 24 math functions, 18 finance functions, 17
trig functions, 13 statistics functions, 14 lookup functions plus
logic, date, text and info functions — with many more on the way. It
also supports splitting panes and freezing, as well as creating
borders and changing fonts, colors and alignment. Landscape and
portrait views are both available.
