Love the app I love the app, but what happen after June 22? Will I no longer be able to use this app?
Jeremiah Brown
Very good Graphing functions are not always intuitive. Creating long equations can be tricky, since it only displays a limited amount of text. But overall this is my calculator of choice.
Alexander Johnson
Great In desperate need of a UI enhancement, other than that does great. Would love some touch inputs on graphing mode
Henry Santana
Very good except for solving quadratics This app does not accept noninteger coefficients in quadratic equations. This is a serious limitations, most applications are not so tidy. Ok for students

MobileCaltronics, LLC April 22, 2015
MathPac will no longer be sold or updated after 06/2015; however, it will continue to work on your device until 06/2016. Great In desperate need of a UI enhancement, other than that does great. Would love some touch inputs on graphing mode
MobileCaltronics, LLC May 20, 2014
I agree!
touch input on the graph is the current "TODO" :) Good, but bad U.I. the program itself works very well, but it is unsightly and difficult to navigate. still prefer my graphing calculator, but will do in a pinch
MobileCaltronics, LLC September 11, 2013
I have been working on a new UI since April. I do hope to have it published by the end of this month.:) . Why so many updates? Make your changes & update no more than once a month.
Fixed within 24 hours It works great now. They fixed within 24 hours. They really stay on top of their program.
Terrible The new update automatically crashes Motorola Droid Razr Maxx HD
Old, not maintained well Crashes my galaxy s2 about every forth time loaded. Running ics 4.0.3. Table view pops up spontaneously when I try to move graph display. INCREDIBLY ANNOYING!!!
Excellent Value I have installed this app and Stat PAC on both my Kindle Fire and Google Nexus. I heartily recommend both apps, but really praise the Google Nexus version. It is outstanding. I am finding the Nexus to be a truly educational device, and these apps are one of the reasons. (I also have GeometryPad, SkySafari Plus, Solar Explorer, and MathStudio installed.) These are expensive apps, but are so worth it to make my Google Nexus a true educational resource. My only recommendation would be that you take the plunge and buy Math PAC Plus right at the start, and get the whole package in one app instread of two. I see a real potential for tablets in the schools (seven inch is good since it is more affordable). This app should be on a tablet used for that purpose.
Great calculator app I used to lug around my trusty old TI82 to do equations on the go (what a brick), this app is great for picking up alot of the graphing and matricies type equations when you need it.
Accurate and reliable! Very versatile calculator. You can tell it was developed by instructor. Great App A+
No good at remote locations I do some work at a remote location  no phone service, no internet and now no calculator because it needs to do some sort of "handshake" to verify that I have an authorized copy. If I could give this POS a negative number of stars I would.
good so worth it. save me money. haven't had problems with it yet.
Great fully functional calculator This is a great calculator capable of replacing high end graphing calculators. However it could use a UI update.
Not worth $15 Missing a lot of the functionality of an actual graphing calculator. Theres no way you could actually use this any college courses. Not worth price.
Worth the expense Just like having to learn a TI calc, this app is WAY more useful with color and a bigger screen on my galaxy s. Using it for advanced statistics.
An excellent app written by an expert who is helpful and supportive of the end user. Thanks for the last update 6 out of 5 stars! Perfect.
I don't see pi anywhere in the calculator. Edit: changing fonts fixed symbol issue. Tested on another calc app
It is a complete and easy to use calculator for all educational levels.
Pricey. Not my favorite calculator, but the author is developing a fine product and cares about supporting it well. Excellent tutorials.
Best all round maths app I have found. Well worth the price!
As a calculus teacher, I recommend this application to first year calculus students.
I tutor math. Using my phone is much easier than carrying another calculator.X

Graphing Calculator MathlabPRO
If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.
Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the highquality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x and y values and displays them as well.

AlmostTI  TI Calc Emulator
AlmostTI turns your Android device into a Texas Instruments graphing calculator. It fully emulates TI84+, TI84+ Silver Edition, TI83+, TI83+ Silver Edition, TI73, TI83, TI85, TI86, TI82, and TI81 calculators made by Texas Instruments. And yes, if you have got a tablet, it will become a really BIG TI calculator. AlmostTI also lets you save your calculations at any point and then select from several previously saved tasks.
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:

Desmos Graphing Calculator
At Desmos, we imagine a world of universal math literacy and envision a world where math is accessible and enjoyable for all students. We believe the key is learning by doing.
To achieve this vision, we’ve started by building the next generation of the graphing calculator. Using our powerful and blazinglyfast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Sliders make it a breeze to demonstrate function transformations. It's intuitive, beautiful math. And best of all: it's completely free.
Features:
Graphing: Plot polar, cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time  and you don’t even need to enter expressions in y= form!
Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph
Tables: Input and plot data, or create an inputoutput table for any function
Statistics: Find bestfit lines, parabolas, and more.
Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window.
Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger.
Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. It can handle square roots, logs, absolute value, and more.
Inequalities: Plot cartesian and polar inequalities.
Offline: No internet access required.
Visit www.desmos.com to learn more and to see the free online version of our calculator.
Note: the app doesn’t yet support saving & sharing of graphs. If you need to save and share, we recommend visiting www.desmos.com on your device.
