United StatesThe perfect tool for students, teachers and engineers, built on an extremely powerful algebra engine, SymCalc solves any math problems from basic arithmetics to university-level advanced math. It offers all the advantages of an advanced graphing/scientific calculator mixed with the convenience of a modern mobile app. Features overview: - Exact arithmetic. 5/15 is 1/3 and not 0.333 (unless you select rounded numerical mode) - Store unlimited number of variables, create custom functions - Algebra: operations on polynomials, such as expansion and factorization, collecting terms, division with remainder, etc. - Calculus: derivatives, integrals, limits, taylor expansion, etc. - Linear algebra: matrix operations, determinant, rank, reduced echelon form, characteristic polynomial, etc. - Solvers: single equations or systems, symbolically or numerically, differential equations - Complex arithmetics - Graphing - Session management: export, import sessions or create PDF files - All built-in functions come with descriptions and examples - Fully offline This free version of SymCalc provides basic symbolic arithmetic features for free. A paid subscription unlocks the more advanced tools and online sharing capabilities. - Length of subscription is 1 year. - Payment will be charged to iTunes account at confirmation of purchase. - Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period – Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal – Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase Terms of Use: http://voxeloid.com/symcalctos.html Privacy Policy: http://voxeloid.com/privacy.txt

It is simple and keeps history of operations.
United StatesLike it, but UI fixes needed.
I have been using this for about a day now and I love it except for some UI issues. So I will be using my other favorite : Pcalc Lite half the time at least. 1. Swipe up to switch between apps causes numbers to be entered. I am always switching back and forth between my data feeds and the calculator and every time I return, I need to delete unwanted characters from the swipe up gesture. Really annoying to do this hundreds of times a day. Pcalc does not have this problem, so please do what ever they are doing to fix this annoyance. 2. You need slightly different color shades around the numbers and another different shade of gray around common operators to guide fast number entry. The two color UI is kinda pure but not worth the slowdown caused for entering numbers. People like me are switching back and forth between multiple engineering apps each with its own key layout, multiple times per minute. So a bit of guidance through color is useful. Again, look at Pcalc for a tasteful example. Also, it would be nice to get rid of the bright background on the answers and just use white text on black - just a personal preference. Thanks for this awesome app!
United StatesAdvanced college math? Not even close.
I don’t know what college is being referred to by this developer but it’s not the one I attended. There is nothing here that wasn’t covered in my high school math classes. At best, these are sophomore year math at any top engineering institute. I was hoping for at least a bit of Symbolic Logic and brane calculations. Something useful in physics and knowledge engineering. Nope. Not here — not even with the subscription, not with the + version. This is a typical CAS port. Looks like it’s back to Mathematica.

It is an excellent application. It is very easy to use and it is far more convenient than the average calculators app I have used so far. I quite recommend it.

These should be free

works with all numbers and gives you the choice to approximate irrational and transcendental numbers or leave them be.
United StatesA little concerned
I have used this app for also number of years so I don't really understand why it is now subscription based over an outright purchase? The difference between the Symcalc and Symcalc+ are not properly explained. It seems like the developer is hoping on board the subscription train like most others, but the there doesn't seem to be any added features with each update as is normally associated with a subscription. The part that finally made me write a negative review is the fact that the app cannot handle the simple function "integrate(sqrt(cosh(x)),x,0,1)" it just returns the same function without any error message. The hp49 app on the app store can handle this easily! Dev please fix this.
