Thank you for the great app! It's so useful for calculus and trig! Also, the support is impeccable!

by Jacob(March 7, 2011)

I use it as a teacher to model systems; works great!

by Edward (February 25, 2011)

Edward I was looking for an math app similar to HP T-83 with financial functions, such as amortization, present values, compound growth rates.

Seemed expensive at first, but worth every penny for the calculator alone.

by Rebecca (February 23, 2011)

I tutor math. Using my phone is much easier than carrying another calculator.

by Tyler (February 20, 2011)

Vary useful. Was debating on getting this due to the price, but happy I did.

by Jeremy (February 14, 2011)

Great app!! Nice not having to look at a pixelated graph.

by L (February 13, 2011)

Didnt get a refund ..............

Let me add comment here: I have never refused or delayed a refund. This is an outright lie, but no way to remove from Market comments!

TOP NOTCH!

Excellent. An app getting better and better. Well done. Thanks. by Eric (February 9, 2011) Comprehensive apps have a learning curve. This author has detailed tutorials on his website. Pgm works well.

by Roberto (February 9, 2011)

L'ho acquistato ma nn me lo fa scaricare -.-"

by Byron (February 8, 2011)

Bought to test features. It's ok, unweildy interface. Graphs look very polished. Not what I need & doesnt justify the price. I have a degree in math.

by Revmixman (February 6, 2011)

You get what you pay for. This is by far the best math tool you could ever own. I love how the graphs look. Squeeze theorem looks awesome on this app.

by maui77 (February 6, 2011)

Great application. A nice addon would be multitouch support for zoom in/out on graphs

by Zack (February 6, 2011)

Great fully functional calculator This is a great calculator capable of replacing high end graphing calculators. However it could use a UI update.

by SherriC (January 23, 2011)

This application is a Godsend for my Intermediate Algebra class. Well worth the $14 bucks!

by Nick (January 16, 2011)

Good for easy graphing by Franz (January 10, 2011) Missing the differentiation at a variable point.

Excellent.

by dobbs3x (December 29, 2010)

Great app! Did everything I needed for my college algebra, functions, graphs, matrices etc. Always updating and listens to feedback.

by allan.a (December 28, 2010)

I wasted a lot of time on free calcs. If your time is worth ANYTHING, suck it up and BUY this one. Great app!

by Donald (December 28, 2010)

Great app. Must have for engineers and math students. Please add ability to edit equations on calculator. Working with fractions would get 6 stars.

by cody (November 19, 2010)

Good program, needs ability to graph polar coordinates

by William (November 10, 2010)

Outstanding product and equally outstanding response to support requests and questions

by A (November 10, 2010)

Very useful calculator for Android. Excellent support.

by Monte (October 19, 2010)

How do you calculate derivatives

by Steve (October 9, 2010)

Best calculator on the market, responds quickly to emails and usually with an update not too far behind :)

by Hailee (September 28, 2010)

Awesome! I just wish i knew how to use the "Math" function set up like an actual graphing calculator (or have one added)! Love it otherwise!

by Alan (September 23, 2010)

A very good application that the author always updating, excellent.

by Darren (September 12, 2010)

Im downloading the update now. Let's hope for augmented matrix support! I find having to creates separate matrix for answers to be kind of tedious.

by Tom (September 12, 2010)

Best calculator app for android and keeps getting better. Developer is very open to suggestions.

by yasiel (September 10, 2010)

It seems to me that is very good... i'm waiting just to try it out in my next calculus test.

by Chris (August 16, 2010)

PERFECT APP! Does everything and more! Perfect for college math!! DX

by kevin (August 8, 2010)

Excellent app. Does almost everything the TI 83 and 84 does. Great for my math classes.

by jane (July 26, 2010)

Nice! Very good and useful calculator.

by nati (July 15, 2010)

Very versatile calculator. I asked for a mode button. Update has one! Support is the best.

by Mel (July 13, 2010)

Must have for Algebra! Does so many different things. Really good grapher too./p>

by JFEdgar (July 12, 2010)

Very very good for 15 bucks. Easy to use graphing calc with you at all times.

Doesn't use variables to store data, But overall useful for simple analysis. Needs more work, although the dev did a great job.

by Doc (November 15, 2010)

Thank you I finally understand web site awesome tool. A+

First of all I have been the Assistant Supervisor at a college tutorial lab for the past ten years. I have seen the Sharp, TI-83, TI-84, and Casio and personally own a TI-89. I was asked to field test the MathPac at work and I admit to being skeptical at first but, now bow to the fact that this app rocks! The upside? It is compact, affordable and as much as I have used it, the capabilities of the 83/84 as it applies to College Algebra, Trigonometry and Pre-Calculus. The downside? For me it was the navigation because I was not use to a touch screen, but for the younger generation this should not be a problem! I happily back this app and see it as an affordable alternative.

I think this is a great APP and I have been working with it since I loaded it. I am very happy with the MathPac. I am saving up to purchase the StatsPac. The more I use the MathPac the more I like it. I think Mathpack is a great value.

Hi Singh,

Crackberry posted the update today just before 1 PM Pacific. The original 5 X 5 Matrix I sent you is now correct. Also, to push the evaluation further, I tried an 18 X 18 Matrix. It also is correct.

Thank you!

The application looks very good and you have solved the problem. Thank you again for such a quick response. You have developed what appear to be the most advanced math applications for blackberry. If you’re ever looking for ideas for future development of another application or if there’s anything I can do for you on these, let me know.

Ed
