Works absolutely perfect! Why pay $85.00-$100.00 for a graphing / scientific calculator when you could spend just under $4 for something that does the EXACT same thing?!? It does EVERYTHING as promised, NO crashing, NO freezing and it's so stinking easy to use! I think I have maybe only written reviews for three products total, with this one being the third. That's how unbelievably awesome this app is! So THANK YOU sooo much to the developer of this app for creating such an AWESOME and unbelievably AFFORDABLE product!

Tim Chandler

Awesome app, best calculator on the market place. One of my favorite features is the ability to save functions. I can make my own conversions and really simplify some complicated calculations. Only thing that is missing for me is the ability to use it windowed on my tablet.

Enrique Rueda

Best calculator app As a college student taking calculus, I was looking for an app that could help me on my tablet, a Samsung Note 10.1 (2014). This app allows for half-screen which is amazing! After using the app free for a year, I was so happy and satisfied with it that I decided to buy it. Little did I know that buying the app allowed 3D graphing which is really helping me for Calculus III. The only downside is that it does not do integrals and other little things essential in calculus. Overall I am extremely happy with the app and it's developing team.

Kevin

Great App Works very well especially for graphing. Equivalent to a basic graphing calculator without a CAS system.

Michael Rector

Pretty good app Been using the free version for a while and decided I wanted to give them my money. Threw my money at them and am enjoying the app. A few features missing which make it less powerful than my emulated ti-89 platinum, but in all honesty that isn't a huge deal. The addition of solving derivatives, indefinite and definitive integrals, along with some other calculus features would be an improvement which would result in me cranking this rating up to 5 stars.

Justine Me

Flawless! If you are taking Statistics and cannot solve an equation with this calculator, YOU haven't learned all that it can do yet! Read the manual in Adobe because this calculator "woke up like this". #flawless #usererror

User reviews

Mathlab Apps, LLC March 18, 2015

Dear Jessica! Thank you very much for your nice feedback and financial support to develop the app. The app is still not perfect because it needs additional modules for integrals, limits, and statistics that we are working on to implement. We share what we have and try our best to make the app even more convenient tool to comprehend math with ease:) Mathlab Apps, LLC March 26, 2015

Thank you for your input, Tim. We'll think how to make the option to show the window with your functions offering to choose them. If you have your own vision and probably design how this window might look at in the screen, please share. You may use the screenshot to draw this window. Tell us more: calc@mathlab.us Mathlab Apps, LLC April 3, 2015

Thank you, Enrique :) We are implementing integrals now, but it is so difficult (especially because many indefinite integrals cannot be expressed in terms of elementary functions) that it probably needs a few more months. Mathlab Apps, LLC March 18, 2015

Hi Michael! Thank you very much for buying the app :) By the way, you can use it to count derivatives: http://help.mathlab.us/211-derivatives.html Best calculator on Android, 2015 Probably the best Android calculator in my opinion, year 2015, though by no means perfect. The reason is b/c: 1) it supports multi-window, 2) it supports graphing ability, 3) it is a scientific calculator with constants commonly used in math. I've tried various calculators and none has all of those things in one package.

Dang near essential This app has been an integral part to passing my math courses since I discovered it last year. I recommend it to everyone I know who struggles with math.

Mathlab Apps, LLC March 25, 2015

Thank you very much for your nice feedback, Cody! We are so happy that you and everybody who starts to use the app become more and more skillful and confident in math ! Congratulations! Best app I ever paid for! The free version of this app was so amazing that I bought the one that costs real money immediately. I origionally started using this app because I did not want to spend money on a graphing calculator. I use this app on a Note3 which has a lot more screen real-estate and pixels than a TI calculator; this makes it great for regular computation as well. This app is amazeballs and is fun to use. 10/10 Worth the six dollars I paid for it. (p.s. a dark mode/theme would be great for oled devices as a power-saver)

Most useful calculator. This is amazing. I bought it to encourage the developer. I don't even need the graphing.

Mathlab Apps, LLC April 22, 2015

Thank you very much, Matthew! We really appreciate your support and encouraging. We'll amaze you soon :) Amazing Does everything you need for the cost of nothing. Free version is just as good, but it is worth paying to give the congrats and props for such an awesome program.

Mathlab Apps, LLC March 17, 2015

Thank you, Derek! Mathlab Apps, LLC February 3, 2015

ERROR_SECURITY means that you have tools that block license verification. Uninstall or turn them off at least. Tools that designed to get paid apps for free. If it does not work for you, we will refund your purchase.
...
It does not check for specific apps that you might have installed. The app does not even have permission to do that. Mathlab Apps, LLC March 15, 2015

If it does not fit on one line, use variables just like in your own example. A=[[...]], then use A on next line. That way you will not have to repeat it again and again. If you need column vector, don't forget to transpose it b^T. Vectors are row vectors by default. Perfect Nothing beats this app. Took a while to get used to but now I've got the hang of it, definitely a life saver!

Mathlab Apps, LLC March 10, 2015

The video (8 min) shows how to use the app, different features etc,: www.youtube.com/watch?v=doIYR6hUCpg The User Manual online: http://help.mathlab.us The PDF of the User Manual to read it offline: http://help.mathlab.us/uploads/1/4/4/1/14418664/graphing_calculator_by_mathlab.pdf Okay It's okay, doesnt do negative factorials, and doesnt do time graphing. Im going to stick to MathStudio.

Mathlab Apps, LLC February 21, 2015

Hi Zack. Thank you for your input. We'll implement negative factorials and time graphing with motion. For now, the app does everything that is promised in the description. By the way, the app plots parametric equations, for example, x=cos(t), y=sin(t): http://s4.postimg.org/y5wbcvgp9/Parametric.png Absolutely helpful, suggest to everyone This a great application to help everyone with many different aspects of math

Mathlab Apps, LLC September 8, 2014

Yes! It is the easiest practical way to understand math! The curiosity to enter random functions to see how they turn out helps to comprehend concepts and methods with ease! It's time to get A-grades only for all of your math courses. Best Wishes! Mathlab Apps, LLC March 10, 2015

Look at the map of the keyboard carefully once, try to understand the logic of its organization, then it stops to confuse you anymore: http://s10.postimg.org/gvhlgh5q1/kbd_map4.png Best so far Excellent in performance and reliable. Except I can't get solutions at intersection of graphic functions.

Mathlab Apps, LLC February 21, 2015

You can see the coordinates of intersections. Look at this picture with 3 steps how to change settings: http://s16.postimg.org/5oye2ax3p/set_graph_1.png Look at this picture with 3 steps how to see the coordinates of intersections, roots, and critical points: http://s3.postimg.org/eejq2env7/set_graph_2.png Click the button inside of the red line. # What's New

Fast and convenient, Wabbitemu allows you to always have your trusty calculator with you. Because Wabbitemu is an emulator, the calculator it creates will act exactly like the real thing.

Wabbitemu, like all emulators, requires a ROM image. Wabbitemu includes an easy to use setup wizard that will help you create a ROM image for your TI.

Frequently Asked Questions:

1. How do I bring up the menu?

You can bring up the menu by swiping from the left edge of the screen, or pressing the menu key (if your device has one).

2. How do I disable vibration when I tap on a button?

Open the menu and click on settings. Under the 'Skin' category unselect 'Vibrate on keypress'

3. How do I load apps like PlySmlt2 or Inequalz?

To load any file to your calculator you need to first download it to your SD card or internal storage on your device. You can find the official TI applications for the 84 Plus (non color) available here: http://education.ti.com/en/us/software/search/ti-84-plus-family-ti-83-plus-family#view=math-apps. Once you have downloaded the app to your device open Wabbitemu. Swipe from the left edeg of the screen to bring up the menu, and select 'Load file'. Find the file you just downloaded in the list and select it. The file will be sent to your calculator. Apps for the 83+ and 84+ calcs will end in *.8xk. Apps for the 84+CSE will end in *.8ck or *.8xk.

4. I'm missing fraction options when I press Alpha+F1! How do I get these fraction options?

Fraction options (and the rest of the Alpha+FN menus) are only available on OS 2.55 MP. Wabbitemu allows you to download both 2.43 and 2.55 MP. You can check your OS version by hitting '2nd' then '+'. Then press enter to go to the about screen. If it not 2.55 MP or 2.53 MP you will need to upgrade.

To upgrade you will need to recreate your ROM by going through the setup wizard again. The setup wizard is runnable if you bring up the menu by swiping from the left edge of the screen. Then select 'Re-run setup wizard'. As you go through the setup make sure you have selected OS 2.55 MP on the OS selection screen.

Mathematics is a powerful calculation software for your android smartphone.

FEATURES

Calculate any formula you want and show them in a 2d or 3d plot. The natural display shows fractions, roots and exponents as you would expect it from mathematics.

In a few seconds you derivate or integrate your desired function, calculate the zero points of your function und show them in the function plot. See all maxima, minima or inflection points in one view.

The easy way of use allows you to solve linear equations in just a moment. Or transform your mathematical, physical or chemical equation to any unknown variable.

You often needs to calculate with binary, octal or hexadecimal number systems? No problem! You can mix them together in one calculation even by using decimal digits. But that's not enough! You can also calculate with any other number system with base 2 to 18.

From time to time you may need to convert units to another one, like Celsius to Fahrenheit, miles to kilometre, inches to foot and so on.

You will also be able to calculate with vectors, matrices and determinants.

All this features are combined in this app and will make your mathematical life a lot easier.
