Oovium

This is all I need :)

great app but absolutely unstable as I lost twice all my work because app don't open anymore. I had to cancel and to reinstall but lost all work.

That's what a touch alternative of excel looks like!!! I am really enjoing using it and looking forward to playing a lot with this tool! Keep up a great work!

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.

The web tutorial only really describes the iOS (iPad) app. The Mac version is different and if you follow the tutorial, bad things happen. Most notably it refers to "hit the '=' key" often but does not mean your physical mac keyboard. Hitting that bizzarely inserts two equal signs in the bubble.

Subscription is paid but you wont let me use the app. Please return my money.

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.

Crashes on launch on iPad. Used platform this to tell developers. Support via Reddit?

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.

This app allows me to prototype engineering design genetic algorithm and genetic programming models before I launch into coding. Great for visually analyzing a single example output to debug the logic. Very useful and handy since my iPad mini is quick and available.
