QSCalc is a Graphing Calculator, Home and Car Loan Calculator, Unit Converter, and a Tip/Discount Calculator all in one easy to use iPhone application.

Are you frustrated because you have to have 4 or 5 applications for calculating? QSCalc will end your frustration. QSCalc has 6 different calculators in this one application.

The graphing calculator is a mathematical expression calculator that not only performs calculations like other calculators, it also displays the formula as you enter it. You may also graph equations of one variable, X. And, the graphs may be zoomed and moved.

The loan calculators allow you to solve for several different values. The unit converter performs conversions for money, volume, weight, and length. And the tip calculator will also split the bill for you. What more could you want?

What's New in Version 1.2

iPhone OS 3.0 compatibility changes
Bug fixes:
- Delete button should no longer crash program when field is empty
- Fixed button states and graphing
- Fixed currency conversion update issues

I am continuing to work on the look and feel to make this utility an elegant and useful tool.

Some of us have not updated to the new OS for various reasons. If you are like myself - this will not work on OS <3.0.

Outstanding effort. Thank you. What a great addition to the iPhone. You could be paying for this and not get all these functions. It just does not get better.
