## What is TI?

Texas Instruments, the No. 1 recommended brand of graphing calculators in the U.S., has optimized its most powerful Computer Algebra System (CAS) math engine for an all-in-one iPad app that makes teaching and learning math more engaging, meaningful and … fun! 

ONE CAS APP. ALL THE MATH. 

Open the door to math mastery with the first-in-class iPad CAS app that delivers comprehensive graphing, data entry and analysis, statistical modeling and calculating functionality. 

Solve equations with algebraic precision, factor and expand variable expressions, complete the square, find antiderivatives, compute limits, find exact solutions in irrational form and more. 

Make math more meaningful by importing images from the iPad camera or photo library and overlaying graphs and equations on them to illustrate abstract math principles in the real world.* 

Visualize crucial connections by observing how equations change — in real time, on one screen — when you touch, grab and interact with shapes, graphs and objects on the screen. 

Graph functions, inequalities, implicit functions, conic sections, scatter plots, statistical plots and regression models, 3D graphs, parametric, polar and differential equations. 

Enter equations in proper math notation so math symbols and formulas on the screen are identical to those in text books and on the board. 

Deepen understanding by exploring hundreds of free activities for Pre-Algebra, Algebra, Geometry, Calculus, Statistics, Pre-Calculus and more from the online Math Nspired resource center. 

Create and store work on your iPad, and share it using your Email or Dropbox account.

### 3/5 — The app crashes and it's not intuitive

*2025-10-19, version 6.3.0*

Unfortunately, the app is way less stable than I expected as it crashed multiple times on my iPAD pro, while doing different things. Also, it's not intuitive: I don't have an easy way to discover the name of the functions for the things I'd like to do. I'm sure that if I insist on using it for some time could get better, but the fact that crashes it's very demotivating. I've used way cheaper symbolic calculators on iOS that turned out to be much more stable. I expected much more from TI.

### 3/5 — Falta actualizar / lack of update

*2025-09-23, version 6.2.2*

Tiene un teclado demasiado pequeño para gráficas / it has a keyboard too small.

### 1/5 — Beschweren

*2024-11-07, version 6.2.1*

Am Anfang ging es gut aber in laufe der Zeit spackt es immer mehr und ich kann kaum noch in Mathe Unterricht mitarbeiten. Drecks App

### 5/5 — Llevo usándola del 2016

*2024-10-07, version 6.2.1*

Esta aplicación la compre en mi prime año de universidad. Estaba en busca de una calculadora programable para mis clases de calculo, física y química. Una de las opciones que mas se escuchaban eran las de Texas en especial las opciones TI, yo en esos momentos usaba mi iPad para tomar apuntes y leer pdf, así que decidí comprarla y me lleve una muy grata sorpresa por que los programas que creaban mis compañeros y que hacían en sus calculadores físicas las podía ocupar en mi iPad. Además de que existen comunidades que te comparten sus programas especializados. Yo recuerdo que tenida un programa que te ayudaba a resolver ecuaciones REDOX de química. Es una herramienta muy útil y recomendable. Pero tienes que investigar y leerte los manuales que Texas tiene en su pagina si quieres sacarle el máximo provecho.

### 3/5 — Why is the TVM solver is missing from the financial math manual?

*2024-06-22, version 6.1.1*

I was using this app to teach my students and suddenly realised that this important selection of the financial math part is gone. I tried to use YouTube to double check if it was there but it was shown that the app should contain this choice. What’s wrong with this app that I purchased?

### 5/5 — Bien buena

*2024-06-16, version 6.1.1*

Que siga mejorando!

### 1/5 — Extrem enttäuschend

*2024-05-08, version 6.1.1*

Verwenden die App im schulischen Alltag. Leider ist die Bedienung der App sehr umständlich und ist in der Benutzung somit sehr umständlich

### 1/5 — Tastatur ist schlecht

*2024-01-25, version 6.1.0*

Die Tastatur verschwindet seit dem Update immer wodurch es so wie 
Unmöglich ist flüssig zu schreiben

### 4/5 — Gute Alternative, ABER…

*2023-11-24, version 6.0.7*

Insgesamt eine gute Alternative zum Handheld. Auch etwas intuitiver zu bedienen. ABER: Ein ganz großes Manko ist, dass kein Splitscreen-Modus möglich ist, was das arbeiten mit App und parallel Goodnotes o.ä. deutlich erschwert. Da muss dringend nachgebessert werden. Andere TR-Apps schaffen das ja auch!

### 4/5 — Need multi window

*2023-11-21, version 6.0.7*

I hope there will be a multi-window function and a screen version such as an actual calculator for use in class
