Andrew Keith

Best matrix app With free step by step solutions this app is very useful for solving and learning matrix and vector operations. Cool new interface too.

Mark Oman

I like it but gives incorrect answers. Great interface and range of tools but I've gotten incorrect answers from the cross product tool which makes me wary of the whole thing. My error case was {2,4,-3}x{7,0,7}={28,35,-28} when the real answer (verified by hand and on Wolfram Alpha) is {28,-35,-28}. Fix the logic and this will be awesome.

Enrique Ceballos

Awesome Great overall. I am a math professor and I recommend this app to my students once we get into large matrices or into situations where we have to put a matrix to a large power. The only suggestion I would give to the developer is to eliminate what's in a cell when one chooses it. It takes time to have to clear the cell instead of just typing the number in

Finally I found a creator that reply to our feedback. I will recommend it to all of my classmates. Keep it up.

Algrebra This looks and sounds excellent, how long will this last in order to learn the concepts and rules?

Decision made I haven't use this app a lot but for the short time I have, its been doing well til this pass week. It keep force closing on me. If it keeps up.....can we say uninstalled. (Update 2/4/14): time has passed since my last statement. I must say there has been a lot of improvement and I do like the sleeker look it has. I have used this app a lot and it has proven to be very useful. Thank you for fixing the bugs that was causing it to force close!

Thank you for your review, Brittney! ComfyMobile December 11, 2013

Dear Sebastian! If you want to fast closing, you have HOME button on your device. Shows steps I accidentally reduced my B matrix too far, and it erased a row in A, mostly: having to clear wrong data from each segment before entering correct #'s is a pain. Besides not preserving the column data and this extra step it's a gem for checking work.

This feature is made to prevent data loss in case of accidental resizing. We plan to add quick removal, thank you for your review Can't even get a determinant right Kept telling me the determinant of a matrix was 4 when more reliable software and my own calculations confirmed it was 1. Piece of junk.
