Oovium 4+

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.

Promising

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.
