Perform mathematics calculations by bumping numbers together.

Version 2.0.0 and above is MAJOR version update.
Previous users of this program will find that the interface has been COMPLETELY redesign, hell even the Tag engine itself have been completely rewritten for speed.
You will find the whole program to be sleeker.
With all the motions the program will be generating, you will literally be seeing how numbers interact with each other.
The program will be "talking" to you in a way [via text, not voice] through the top panel, a new feature created for the kids [I will explain it later].

The reason for this drastic change is due to this single reviewer by the name of "Cobalt Chameleon":
"I teach 5th grade deaf students, so we rely heavily on visual learning.
I love this whole concept & I know my incoming students are also going to love it as well.
They're going to latch onto this quickly and have fun doing math. Wish I'd thought of it!"

When I first created this program, it was to further a concept I have in my mind, to create a calculator that visually shows the interaction of numbers.

After I am done with this app, I moved on without a second thought.

But then I saw this one review months later [it was the only review at the time] and it makes me all emotional when I realize that through a teacher, I have benefited a group of deaf students.
It made me cry a little [Yes, I am a man and I cry...] to know that a simple idea from me could help a small group of deaf students.

With the understanding that there will be children using this, I immediately drop all my projects and work on this again; I have to redesign the whole thing for them and I’ve dropped the price to $0.99.

I’ve made it more lively, added more features, made the buttons bigger for them.
When things get complicated, there will be textual explanation so that the kids can understand.
The by product of the bigger buttons also means that it’s now usable on the iPhone, hence, this version is also iPhone compatible!

And if you are the kids reading this, don’t worry about the sound; I have made sure that all you need to know can be read, I am sorry, I didn’t know you couldn’t hear the sound, I am sorry kids.

This is for you kids...and your Teacher Cobalt Chameleon.

I was a teacher before; I feel so much for the kids and the teachers.

And to Cobalt Chameleon, I am not a "company", I am one person, when you wrote this review, you wrote to me.
I hope this will make you and your kids happy, I felt so happy writing this and from all the work I’ve placed on this new version with my heart.

If you have any suggestions, please kindly drop your email along with the review so that I can get back to you if necessary.

This is one of the positive things my user says about version 1 of this app:
I don't care how useful this is...but it takes the iPad cool factor to another level.
I downloaded it and use it to wow people who want to get a closer look at the iPad.
My Grandson plays with this thing more than his other toys and I've take advantage of that to teach him math...this has so much potential...I hope the author of this app knows this as well! Looking forward to updates.

What's New

Version 2.0.9

In my attempt to upgrade the app to be 64 bit compatible, it ended up working great for the new iPhones but completely kills it for the older versions [iPhone 5 and below].
This problem is now fixed, this app now runs smoothly across all versions !

Ratings and Reviews

Very Nice App


Being a Star Trek fan, this is particularly nifty. My only suggestions would be to add the ability to add labels to the tags to assist in reference during long, multi-step calculations to facilitate re-use of tags in building larger calculations. Second, I would also suggest adding the ability to have multiple pages of tags that can be stored and recalled from memory. I also find that once I put something into the memory, the only way to completely clear it is to completely exit and re-enter the app. Way to think outside the box, great app. This has become my standard replacement calculator, since Apple decided not to include a calculator in the iPad!



Since i am visually impaired the interface is a real help. Unfortunately, the visually impaired often have troubles in the field of mathematics. When you start throwing numbers and symbols around our vision can betray us.

The reason I didn't give it four (it is extremely rare that anything gets a five!) stars is the limited types of operations that can be performed. There does not seem to be a way to enter advanced algebraic, trig, or calculus equations. Not even something as simple as: 3 a = 12

Based on the description I should have expected this limited functionality. But I was still hoping that this type of interface might help me with a life long problem with math.

A Breakthrough


I bought the previous version of this app and was impressed with its possibilities. This new version is even more promising, and I congratulate the developer on his achievement.

Traditional calculators are limited to a small display window because of technological limitations on those devices. This app allows for the user to place and arrange all of the numbers that they will be using for a calculation on a large screen BEFORE they start doing any calculations with them.

There's only a few things that are missing, and I hope the developer reads this review and considers these suggestions.

When a number is created in this app, it's in a field called a called a "tag". With traditional calculators, the user has to remember what figures they are going to be using, and/or remember the results of previous calculations. Not only that, but they have to remember the relevance of each number. For example if you added John's restaurant bill of $4.00 and Mary's bill of $3.00, you'd have their combined bill of $7.00. Just seeing "4", "3", and "7" in a calculator window is limiting, and with this new app it might finally be unnecessary. There is no reason that each tag generated in this app couldn't have editable text attached to it. The tags have enough space to accommodate a label, and the "report panel" at the top of the screen could show both the labels AND the math used to get a resulting figure... which could also be labelled.

Also, it would be useful if the app allowed for the ability to create a "corral" on part of the screen where labelled numbers could be placed/stored- so the user can continue to work on new, relevant calculations on the rest of the screen. That way, tags that were in the "corral" would not be affected by calculations that the tags outside of the corral would. This would be useful if a user were exploring different mathematical scenarios with interest rates or something, and needed to (1). use the same numbers again and again, and (2). reference the results of previous calculations. If an editable labeling feature were available, keeping all of these numbers in a "corral" would keep them all visible, individually recognizable, and ready to use.

Lastly, since calculator use is frequently concerned with money, it might be helpful if there were a function that rounded for currency and displayed a "$" before a figure.

This app is truly taking advantage of what a touch screen computer can do and is a marvelous innovation. I hope that it finds a user base, and that the developer continues to enhance the app.
