TouchRPN
A fully unit-aware, scientific and engineering RPN (reverse polish notation) calculator. Great for anything from basic math in the supermarket to evaluating the ground state energy of a simple harmonic oscillator on your Quantum Mechanics final (if they let you in with an iPhone, of course). TouchRPN knows most basic physical constants and units, as well as household, cooking, and "imperial" units. A built-in tutorial will show you how to use RPN if you're stuck, as well as how to access the advanced features.
Now available on the app store:
TouchRPN 1.1.1 ($5.99)

Beta Program
If you find a bug/etc or have a feature request, send me an email, and as I work on it, I'd love continued feedback! If you want to participate in the beta process, download Erica Sadun's free UDID Helper app from the app store and send me an email at dstaudigel@gmail.com with your UDID. Once I respond that your ID has been added to the program, download the following code:
Decompress the folder and drag both of it's contents (a .app, which appears as a folder in Windows, and a .mobileprovision) simultaneously to your iTunes library. Then sync your iPhone. Alternatively you can use Apple's iPhone Configuration Utility to install both the provision and the app.
