Oovium

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.

I have oovium classic on my iphone, but the paid version is too expensive, as well as too limited in accessibility to afford. I WISH there was a pay-once option, (not sure if I know enough to say this, but $30 a year from each user is quite excessive, and presumably why the app has only 17 reviews for the 4+ years it (the paid app) has been on the app store.) If you made the app into a one-time purchase worth at least no more than $10, but ideally $3.99 or less, then you would have exponentially more purchasers that would (likely) result in well-over 20x your current earning rate. Then, if necessary, raise the purchase price for new buyers by maybe a dollar or two, once Oovium has gathered a wide-spread reputation, and earn even more. You could possibly obtain donation money as well from strongly-supportive clients. The only applications that can somewhat-justifiably get away with $30+ yearly subscriptions, are name-brand tools like adobe photoshop, Microsoft Office, etc. However, the most painful thing to see is that Oovium is Apple-exclusive. No one is going to be able to save Oovium if someone creates an open-source donation-based alternative with wider cross-platform availability.

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.
