My app of the day is powerOne Financial Calculator from Infinity Softworks. It’s free — or $4.99 for the iOS Pro Edition. It replaces your device’s built-in calculator with a more fully featured replacement.
It also provides dozens of templates to simplify the most complex calculations.
Or, select from a library of downloadable templates numbering in the hundreds.
powerOne’s approach to complex business, finance, engineering or scientific calculations is driven by filling in a table of values to achieve the desired result.
powerOne on my iPhone is the tool that has finally let me put away my vintage HP12c calculator. And for that alone, it is my app of the day.
