2nd Time Around  Still Awesome I bought this app back when it was $15, switched phones and now I needed it again. Yay, the price went down greatly, but the app is even better! Thanks Singh!
Joseph Cush
It keeps not working for me When I try to graph the stats inputted it shuts down to the input screen. It seems like a great program but I can't use it. I have a Note 4. Please fix it
Garth Michaels
Best of the Best This extensive graphing calculator is the most beautifully laid out, comprehensive and useful math and statistics program in the Android market. Like a truly fine wine, it is worth every penny. Smooth as silk and highly recommended!

ie.wojtek Good app. I am happy to use it. Question/Suggestion to programmer: natural input would be good update.

Hi Joseph,
Can you please send more details to singh.kelly@mobilecaltronics.com.
There are 38 different screens from the stats portion of the app that can graph so I would like a few more details so I can remedy your issue. Thank you Good Casio like operation. 《v11.1》 Good app for me who's been using a Casio since high school. The lists for regression and statistics doesn't have an export / save function (but it can import). I'd like it better if it can export lists, better (clearer) interface concerning its functions, and if it has a computer algebra system

Hi David,
.......sounds like you have some mem storage errors let in the cache.
Please uninstall all previous versions of MathPac+ from your device.
Reboot your phone/tablet then go back to GooglePlay for a fresh install.
let me know if this does not work for you. :)
Out $25 & no app  UPDATE UPDATE 2: If you are trying to decide between this and Math Studio, let me save you the trouble: THIS is the one to. FAR more useful by a long shot! UPDATE: Starting with the last update the app began working again. When it works, it is the best calculator app out there; I have tried over 10 of them. To the seller: I have the receipt for both purchases and 2 emails from you. So, I better be "licensed." OLD: I have paid for this app twice. From Amazon & Google: it stopped working both times after a while.

Google Wallet has no record of Hjalmar Schacht ever purchasing an app from me. I am happy to refund your money, but you must tell me who you are.
new: OK, I still cannot find you in my database, but as long as you're happy and the app is working properly I am happy too :) No Longer Meh I haven't used most of the the functions yet, but the calculator function doesn't keep track of small numbers (e.g. 1.602*10^19 = 0) well. Edit: nevermind that seems to be totally fixed in the most up to date version!
MobileCaltronics, LLC September 11, 2013
This was corrected in v9.9.
Thank you for bringing it to my attention. :) Stops working a lot I guess this OK, I'm using it for a college level modeling course but it stops working every time. Very frustrating. Just going to buy the $107 calculator my prof recommended.
MobileCaltronics, LLC September 8, 2013
I did send an email asking for specifics, but never got a reply:( Good but... I'd like the ability to use user defined functions (possibly y1y9) in the calculator section. The calculator section is decent but could stand to use more functions for convenience (eg arcsec, floor, etc). Overall, I'm impressed. This calculator is leaps and bounds above most graphing calculators on Play, and I've tried about 20 of them.
Great app and support This app is great. It has everything I need for my classes at an exceptional price compared to going out and buying a graphing calculator. I originally purchased MathPac graphing calculator instead of MathPac+ which I later found had a few things I needed that the first program didn't. I contacted the developer as instructed and was refunded my money for the MathPac graphing calculator purchase the next morning. While I haven't had to contact many developers for support, I was pleasantly surprised at the speed and quality of service I received. 5 stars all the way.
Simply Outstanding I have struggled with visualizing aspects of cal wasn't culus and my TI84 just cutting it. This calculator has, in a matter of days, significantly improved my understanding of limits. The interface is simple and the graphs...beautiful. It seemed pricey at the time I purchased it but after a few minutes of using it all reservations vanished. I can't adequately describe how much I love this calculator.
Brilliant Originally used this excellent calc as I couldn't get my preferred calc on Android. Math Pac has done everything I need without fuss. Best handheld all round stats and Math calc I've ever used, outstanding. Developer answered my every query next day with the best user service I've seen in years. Would give it six stars if I could. Highly recommended for students and professionals.
Impressed my Professor Although obviously not allowed on a test, it allows you to do many things your standard graphing calculator cannot, such as graph x= equations and get imaginary numbers in answers. My old calculator would just cough up errors. Immensely helpful as this makes it easier to check my work and get answers when an example may not exist for a certain problem. Very powerful tool here. Probably gonna save myself headaches countless times.
1st impression I have a couple calc and stats courses over the next semester or two.. a little pricey for an app but has potential. looks good after 15 mins use, with minor issues. Not optimized for 320x240 res (u8100), but functional. Needs a2sd; ~3mb on internal partition. Will be studying for finals this week and will rereview if I get a chance to use it.
thanks for constant update i like devs who constantly offer updates for app. give it a 5 star
Great app, great service This is a great app. I will be recommending it for my students. It has full functionality, on screen help, video tutorials for every function on the developer's website, an emulator I can display in my classroom, and developer who is unbelievably responsive to inquiries and suggestions.
Functional, but sloppy. Does the stats, but menus look like an old BASIC program. Would rather devs just used the standard Android menus.
Better deal You guys update this all the time. Awesome, simply awesome calculator and worth every penny
Awesome app Love the amount of things you can do with this. Who needs a TI calculator, when you can have this instead!
Perfect app! I was impressed by wide functionality of the app, I thought that there are no app that have all the functionality I need, but it exists :) And it works fine both at smartphone and at Acer Iconia Tab A500, that is helpful for collaboration
Good app, but can't use On Acer Iconia Tab A500, installing this app causes Acer content folders to force close on launch, every time. Can't imagine why this is happening, but uninstalling Mathpac fixes the problem. So I have a $20 app that I can't use unless I'm willing to lose Acer content folders. Reported this bug to the developer over a month ago, and response was quick and courteous, but I still can't use my $20 app. seems like a good app otherwise. Update: Long since replaced my tablet and phone. App works well now. Probably has worked well for everyone except A500 owners, but I only recently reinstalled the app.
Worth $20 My preferred calculator is the TI89 Titanium, so I have rather high expectations. While it doesn't have 3D graphs or the ability to do just about any of the functions from the main calculator (if you know the correct shorthand for it), it's adequately robust enough that I can still do any of my classwork in my upper college level maths even if I forget my TI89 or the batteries had died. (The catalyst for me downloading the app) I'm glad I bought it.
Very useful app, has a lot of information, it's going to help a lot in my trig class.
Excellent. I would like some additional functions such as working with differential equations and showing derivative equations rather than a value.
Regressions do not calculate or plot residuals Nice application for the most common elementary cases but has no flexibility. It calculates and plots the regression line but I could not find a way to calculate and plot the residuals. Statistics Calculator does the same limited regression for free.
MobileCaltronics, LLC September 11, 2013
Plotting residuals was added v8.5
Thanks for pointing out this need!^_^!
Although it seems It seems that other people like this app but dont get to excited. I do not like the TI89 because it has to many buttons with no organization. This is too organized. For the basic calculator there is no way of typing in the derivative. But do not let that alarm you it has many other features but many will be useless to what you want them for. The UI isn't all that good. Im going to stick with mymathlab calculator app for now
MobileCaltronics, LLC October 29, 2013
I must agree  the UI is the weakest feature.
I am working on this. There are many, many changes and I want to test them all before I publish a new release using the navigation drawer and Action Bar Icons. Please look for new nav drawer/actionbar release soon:) After that I will start on phasing out basic buttons and putting in Tiles w/Icons.
sk Powerful, but....... This program is very powerful, but the graphics needs a lot of work. Sometimes the butron got cut of, so its really hard to press it. But overall its a good program.
What's New
Corrected an issue with selected GREATEST INTEGER functions not displaying graph.
Darkened the INVERSE FUNCTION GRAPH to allow for greater contrast. :)

Free Graphing Calculator
Free Graphing Calculator
Does far more than most of the paid calculators out there . . . let alone the free ones.
Features:
1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:
• the usual arithmetic functions and exponentiation.
• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.
2) Graphing. Capabilities:
• Graph up to four equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
• Graph in polar coordinates.
• Graph parametric equations
3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!
4) Constants for scientific calculations  speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation  i.e, you don't have to key in the value. Again, great for doing physics homework!
5) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.
6) Forgot the quadratic formula? Or the doubleangle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.
I'd love to hear your comments or suggestions. You can write me at the email address in the app. Thanks!

Wabbitemu supports the TI73, TI81, TI82, TI83, TI83 Plus, TI83 Plus Silver Edition, TI84 Plus, TI84 Plus Silver Edition, TI85, and TI86. 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/ti84plusfamilyti83plusfamily#view=mathapps. 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 'Rerun setup wizard'. As you go through the setup make sure you have selected OS 2.55 MP on the OS selection screen.

To run AlmostTI, you will need at least one calculator system ROM. AlmostTI does not include any calculator ROMs on its own, as they are intellectual property of Texas Instruments. You should place your own ROM, preferably dumped from the calculator you own, onto your internal storage. AlmostTI recognizes following ROM files (in upper or lower case):
TI85.ROM, TI86.ROM, TI81.ROM, TI82.ROM, TI73.ROM, TI83.ROM, TI83P.ROM, TI83SE.ROM, TI84P.ROM, TI84SE.ROM
TI85.ROM, TI86.ROM, TI81.ROM, TI82.ROM, TI73.ROM, TI83.ROM, TI83P.ROM, TI83SE.ROM, TI84P.ROM, TI84SE.ROM
For information on dumping a ROM from your own calculator, see here:

Statistics 1
$0.99 for a limited time!
Coming Soon to the Android version  Quizzes & Calculators
Intro Statistics ETextbook with: lessons, flashcards, decision trees, a glossary, and a list of formulas and symbols.
It's the perfect tool for students in an intro statistics course, or professionals who need a Stats 101 book on their phone.
Statistics 1 was pilot tested in a statistics course at Abilene Christian University. Here’s what some of the students had to say:
“It gives reallife examples in each lesson and tables so I can easily reinforce the information I just read.”
“It's a great tool to go to for an easy answer. Instead of searching through a whole textbook I can click on a specific section in the app and find the answer easily and see a graph that represents the idea.”
Coming soon: Quizzes, calculators, and sims.
The app was designed by educational psychology Ph.D.s, statistics teachers, and software experts. Many of us learned stats the traditional, boring way – through books and lectures. We always wanted more interactive, visual, and engaging ways to learn stats. Stats has many abstract concepts so we use realworld examples to anchor your understanding.
 "Cliff Notes  Statistics" book or pdf sells for $16.99.
 "Statistics for Dummies" sells for $19.99.
 "The Complete Idiot's Guide to Statistics" sells for $18.95
