CALCULATE

Whether math and science, conversions, engineering, construction, finance, investing or real estate, powerOne has you covered. There are hundreds of spreadsheet-like calculator templates pre-installed or in the Library, ready right now for all kinds of what-if scenario analysis. Five templates included with this Lite version or buy the Pro version to access hundreds more.

And for those one-off calculations use powerOne's elegant algebraic and RPN calculator. Perform calculations in either decimal, scientific, engineering, fraction or feet-inch format with functions that include powers, logs, trig and more.


GRAPH

Sometimes a number isn't enough. Visually seeing data in the form of a function graph, bar chart or scatter plot enhances understanding like a result never could. For instance, see a bar chart of entered data in Summary Data or purchase additional templates that include graphing via in app purchase. Zoom, pan, trace and analyze in the bundled and in app purchase templates, or add to your own.


CREATE

powerOne is easily customized. It includes a dynamic language to create your own calculator templates. It can be as easy as entering a formula similar to HP Solve or harness the complete capabilities of powerOne's simple scripting language. Hundreds of examples and instructions included. Create one with this Lite edition; create hundreds with the Pro version.
