Oovium is not an attempt to rehash old outdated inventions, but it subsumes much of their functionality. The calculator, spreadsheet, concept map, programming language: Oovium is all of them and it's none of them.
Oovium is the first (but certainly not the last) of an entirely new class of app, the calculation sandbox. It has been made possible by the invention of the touch device and Oovium's clean, efficient and tactile interface, designed for such devices, has been part of its DNA since its inception.
At its heart, Oovium aspires to make powerful, sophisticated and complex abilities (such as those currently available only to programmers) accessible to a wider audience. Oovium understands that increasing accessibility does not mean dumbing down an application by hiding complex functionality, it means making that complex functionality understandable by creating explicit visual representations for it.
The workspace of Oovium is a two-dimensional surface known as the Aether. Upon this aether a user can place Bubbles. There are currently four types of bubbles:
- InstBub is an instance of an object, usually a number, which in turn may be the result of an expression.
- MechBub allows the user to define their own functions.
- GridBub allows for a tabular arrangement of numbers and expressions similar to a spreadsheet.
- TextBub is a node that can be connected to other TextBub nodes in order to create concept maps.
These bubbles can be connected to each other in order to render sophisticated calculations in a visual (and aesthetic) way. Libraries of custom functions can be developed and included in other aethers when needed.
The concept of Oovium has six different aspects; in its current form it contains only one of these six aspects. It is a highly ambitious project with much more planned, that hopes to empower users; it hopes to change the way people think about and work with their computers; in short, it hopes to change the world! Come help drive its functionality; come help make Oovium happen!

World's first pocket computer! Now running on your iPhone.
RPN-65 SD is the iPhone version of RPN-65 Pro, the first complete simulation of Hewlett-Packard's stunning HP-65 programmable calculator for iOS. Produced from 1974 to 1977 at an initial price of $795 (that's close to $5,000 today!), the HP-65 was a breakthrough. Not only was it programmable, it also contained a motorized magnetic card reader - and still fit into Bill Hewlett's shirt pocket.
Experience this revolutionary calculator on your iPhone. With over 180 original HP programs included with the app, you can get started right away.
