Oovium is not an attempt to rehash old outdated inventions, but it subsumes much of their functionality.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!

Crashes regularly and feels like a work in progress. Lot's of work required for this to be a serious app. Disappointed as the concept has potential but the implementation is not intuitive enough and on screen instructions are clunky. Why not just a series of screenshots and text as help rather than the on screen hints which don't even rotate with the screen orientation.

No recent updates, has lost functionality

This app hasn't been updated in a long time. It hasn't kept up to date with iOS changes and hence no longer works as advertised. For example links to Dropbox no longer work. A great pity because it was an excellent app.

Actually it's brilliant...

However, it has one little niggle that for me puts this as a four star instead of the six I want to give it.

The niggle is that if I'm working in Landscape mode and go away from the app, when I return its back to portrait mode and I have to move the iPad. Not the end of the world, I know, but an irritation. I know the developer is aware of this and is looking at ways he can get rid of this niggle so I can give the six stars the app deserves.

The best thing about this app is that you can set up a calculation with labels on the amounts and be able to show it someone who would find a spread sheet mind boggling but will be able to follow the calculation in Oovium. As I said above, it's brilliant!
