Oovium vs Auer Sleek Notes
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Oovium
This app is a novel calculation sandbox that combines the functionality of calculators, spreadsheets, concept maps, and programming languages into a single, visually intuitive interface. It aims to make complex computing abilities accessible to a wider audience through explicit visual representations.
- Calculation sandbox
- Visual programming interface
- Spreadsheet functionality (GridBub)
- Concept mapping (TextBub)
- Custom function definition (MechBub)
- Object instances (InstBub)

Oovium makes my geek heart flutter. - Anne Wind This app is a thing of beauty. - W Smith Jr Wow I love this - OkeyMor57 22nd century calculating - bill knighton This will become Hari Seldon’s Prime Radiant some day. - nicked off Oovium is not an attempt to rehash old outdated inventions, but it subsumes much of their functionality.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!

Verdict
The clearest difference is ratings volume: Oovium at 5 against Auer Sleek Notes's 1. Oovium also leads on device support (4 vs 2) and iOS requirement (15.1 vs 26.0). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 5.0 for Oovium against 5.0 for Auer Sleek Notes. That said, the two scores are not equally well evidenced: Oovium has 5 ratings behind it against 1, so its average is the more settled of the two.
