Oovium is not an attempt to rehash old outdated inventions, but it subsumes much of their functionality.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

outstanding concept but pitiful documentation

Even 11 years old and I’m still a huge fan of this and sadly the programmer is not contactable. i’m only writing this because I see that the subscription is not automatically renewed.I get the feeling this is an abandoned project now which is sad because it is really very cool it just needs some better terminology and vastly better documentation. If you Google hard enough you might find some Vimeo videos which are really bad showing you how to use it but otherwise be prepared to spend a lot of time with trial and error.

Developer Response ,

Thanks for the feedback. Subscriptions have been removed. The app is now entirely free; no need to renew the subscription.

You can contact me via the website (aepryus.com) or head to the discord server. From iOS you can find the discord server from the red dot menu: Help/Links/Discord; from macOS you can use the top menu: Links/Discord.

I’ll be happy to answer any and all questions you may have; I look forward to hearing from you!

Works like my brain

As a mind or concept mapping tool, Oovium is unsurpassed. Most other apps of this kind make you think like the app...Oovium allows me to make a map reflecting the way I think. For specific tasks the flexibility of this app makes it possible to approach diverse problems in the optimal manner, differently from one to the next. In combination with these attributes, the addition of mathematical elements have proven invaluable in modeling a mechanical system. I first map out the general structure of a machine, then I use the numerical functions to flesh out the model. In gear ratios for example, I can enter constant values and immediately see the effect of changing one or more variables in the system.

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.
