Oovium is not an attempt to rehash old outdated inventions, but it subsumes much of their functionality.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

What’s New

Version 2.0.1

- Complete re-write of Oovium in Swift / C
- 300-fold performance increase (a calculation that used to take 5 hours now takes 1 minute)
- The visuals of MechBub, TailBub, CronBub and GridBub have been tweaked.
- Aether import has been moved to the aether itself via the AlsoBub
- Lexicon and 'obj' tab have been removed and replaced by the 'dev' tab.
- Function pointers have been added. Anchor-Tap MechBubs or TailBubs to add a function pointer to your expression.
- Dropbox support has been removed and replaced by rudimentary iCloud support. More advanced features to follow.
- The antechamber has been added. Keep up to date with the latest Oovium news and the Oovium Roadmap.

Oovium is ALIVE!!!

This app is great. It has use possibilities that haven't even been realized yet. I gave it 4 stars instead 5 because of where it is now as opposed to its destination. This app is in its infancy stages and between its developer and the end users, this can grow to something universally useful for everyone.

I needed to utilize support recently and the response was excellent. The developer is also invested in its success. The company is small but diligent. I have been told by the developer that a new iteration of Oovium is being worked from the ground up and taking what is possible now and expanding its possibilities even more.
Keep the faith Oovites

Almost Great

I love the idea of this app. I could be extremely useful and even game changing. I just wish it would work with my Logitech keyboard. I wish it had a manual or a help file or even pop up labels for its icons. I wish it had a loop structure other than recursion. I wish it had graphing and graphics capabilities. Other than that it is so compelling I can't stop playing with it.

Happy to contribute to such a creative approach to tablet-based calculation, which is sorely lacking IMO. I find conventional spreadsheets are annoying and unsuitable for the tablet interface. None of them rank over 3 stars in the store, and I completely understand why. I believe this one could get to 5 given the obvious talent of the developer. From an engineering POV, this is my idea of a great app for entering lab measurements with a library of functions for post-processing the data (a critical use-case I believe for adoption). The only major things I am missing after creating my first function library and dependent ether are strings, constants, and units. The minor issues associated with automatic numeric representation and column widths will undoubtedly work themselves out in near-term updates. I get it ... start with the simplest interface and add complexity only when unavoidable. This is very impressive given the current readiness level. Thanks for yet another reason for employers to issue iPads. I'm very much looking forward to the complete implementation of the vision (suspense deadly). Recommendation: Buy now before the price goes way up.
