I bought a tool called “iShowU HD”, and I plan on creating videos to answer the most frequently asked questions. I quickly tested it by creating a video that shows off the scientific calculator and graphing features of the application.

Version 1.1.3
Saturday, May 30, 2009
Version 1.1.3 was recently released to the App store. This is a minor release with no new features. In addition to a few bug fixes, changes include the following:
- A new function selection screen with a brief description of each function. This should help clarify the cryptic function names such as sqrt() and asin().
- Changed the table view such that it only displays the equations that are toggled “on”. This was a popular request because people wanted more screen space for the functions they care about, and it makes the table screen more consistent with the graph screen.
- Made the application work better on Apple’s upcoming 3.0 firmware.
Version 1.1.2
Thursday, April 30, 2009
I just completed version 1.1.2, and it’s currently under review. As always, it should take about one week for it to be available in the App Store. The new release contains a serious bug fix, and the current most requested feature. Here’s a full list of changes:
- Added the ability to find the exact (x,y) coordinates for roots and intersections using the trace mode. The trace will now automatically snap to points of interest. This was the most requested new feature.
- Fixed the bug responsible for freezing the graph view when touched by three fingers at once. If you ever had the graph freeze while zooming, this is what caused it.
- Redesigned the help page to make it easier to navigate.
- Cosmetic changes to the keyboard. There are two styles to pick from as some of you didn’t like the brushed metal look.
Here is a screen shot showing off the new intersection finder feature:
This is what the new black-stone keyboard theme looks like:
