Your Ti-Nspire programs are my drug of choice, they are addictive, will enjoy them for rest of my life

Thank you.  I had been hesitating to make the purchase as I had wanted to get the apps for TI Voyage 200; 

but I decided to get the ones for TI-Nspire CAS CX instead, basically because it has more memory available.   

These apps you sell have the potential to become addictive so I most likely will be back for more!  

I think I made the right choice.

So, needless to say, I am very impressed.

Beauty is in the eye of the beholder.  Your programs are my drug of choice.  

I am sure to enjoy them for the remainder of my life.  

They are one of the few things worth buying besides food and a good pair of boots.

Perform Gravimetric Analysis on the TiNspire using Chemistry Made Easy

We just added a step by step Gravimetric Analyzer under the Stoichiometry section of

Chemistry Made Easy.


For more information on Gravimetric Analysis read at KhanaAcademy at



Perform Non-Parametric Tests such Wilcoxon, Kruskal or Signed Rank on the TI-nspire

Non Parametric Statistical Tests were just added to Statistics Made Easy package for the TiNspire at .

In particular, you can now easily perform

*Sign Tests

*Wilcoxon Signed Ranked Tests

*Kruskal Wallis Test

*Chi Square Tests

Just enter the given data and watch step by step how the p-value is computed so that you can draw your correct conclusions.

What is particular nice about using these tests , like for the parametric tests too, once you change 1 or 2 data points you can immediately see how that change influences the final conclusion. So, no reentry of all the data is needed, just a little tweak.


Calculus Made Easy was the ONLY reason I got an “A” grade in both Calculus 1 and 2

I am glad that you remembered me. I apologize for the length of my letter. The last time I had contacted your company was spring 2014 when I was taking the calculus classes.

By the way, your CME application was the ONLY reason I got an “A” grade in both Calculus 1 and 2 which helped propel my GPA that year from 3.14 up to 3.64.

I went on to take 2 Biology courses and 2 History courses and got 2 “A’s” and 2 “B’s” respectively and going into this fall semester my GPA is 3.58. My GPA needs to stay above 3.50 for me to maintain my membership in the “Phi Theta Kappa National Honor Society.” I have successfully taken all my required liberal art courses for my Business Administration major and Physics is the only one left. After this course I have only Business Administration course, which was not the college’s recommended way of taken course, but I wanted to get rid of all my liberal art courses so that I could truly be going to college strictly to be taking nothing but Business Administration course.


If I could get through this last liberal art course with my GPA above 3.50, I would feel like I had gotten through the hardest part of college. So at 54 years of age trying to maintain a GPA above 3.50, I need all the help I can get through the use of your Physics applications this semester. Thereafter, I will need your business applications the rest of the way until I get my bachelors degree. So from this point forward, keep my email address in your database because I will be a returning to you to purchase various business applications per semester according to the subject matter, i.e. finance, statistics, accounting, economics, etc.


Per your suggestion, I am going to purchase the Physics app after I send you this email. I got the TI nspire CX CAS a few months ago because of its larger storage capacity for installing many business apps that I anticipate needing to install in the near future. It also has a much brighter and colorful display screen which helps in visualizing a complex problem in picture form, especially in physics. If I can I may send you a few physics problems.

Linear Algebra Made Easy is incredible & enjoyable

User feedback today:

The step by step matrix operations, such as Row Echelon, Gauss Elimination etc are incredible

It is very easy to use;

I like the layout and on the Ti-spire since the processor is faster than the 89 it just makes it more enjoyable to use.

My linear algebra professor does allow us to use a CAS calculator and with the Ti-nspire cx CAS with your linear algebra app… Lets just say my fellow students and professor will be amazed with my knowledge and wisdom… and of course the speed at which I solve matrix operations and systems.
