I started working on the most frequently requested feature, and that is to find roots, minimums, maximums, and intersections. You’ll just have to hold your finger on an intersection, min/max, or root for one second, and a pop-up will display the exact X and Y coordinates.
At this time, the version with the bug fixes (version 1.0.2) didn’t make it to the App Store yet. I heard from others that it takes about seven days for updates to get approved.
If you sent me an e-mail, and I didn’t reply, I still appreciate the input. I read every single e-mail I received related to my Graphing Calculator.

The application became much more popular than I expected, and it is now one of the Top 10 applications.
Unfortunately, I didn’t test it enough before posting the first version, and there were many problems. Because of the problems with the order of operations, some of the graphs are not accurate. I recommend that you are careful when using this for your homework until the next version (1.0.2) is available on the App Store.
Thanks for downloading, and providing feedback.

I sent a new version of the calculator to Apple. It should resolve the problems you guys e-mailed me about, and it will be ready to be downloaded as soon as Apple approves the update.
Here are the list of changes for this release:
- Fixed bugs that caused certain equations to crash the application.
- Fixed the degrees to radians, radians to degrees, and log10 functions.
- Fixed problems with the order of operations. For example: -x^2 will graph like -(x^2).
- Added a button to clear all equations.
- Added an option to reset the grid to the defaults if the user shakes the phone.

I would like to thank all of you that downloaded this application. I received lots of bug reports and valuable input on what’s missing features wise. Some of the bugs would have taken me a long time to find on my own, so I appreciate the e-mail reports.
Before adding any new features, I’m going to get the problems fixed as soon as I can, and send an update to Apple. I think Apple will have to review my application one more time, and my guess is that there will be a new version in the store in about a week.
The most requested feature is being able to find function intersections, and x-y intercepts, so that’s what I’m going to work on once I run out of bugs to fix.
