SymCalc - Symbolic Calculator

I had bought the App, years ago. On my new smartphone it has vanished, I had to install it and it turned out to be a lite version that lacks most of the features, that were useful. The old version was based on REDUCE, the new one has a different CAS, I suppose SymPy. There are no new features. Both REDUCE and SYMPY are open source and can be downloaded for FREE.

Nach dem neuesten Update stehen mir viele Funktionen nicht mehr kostenlos zur Verfügung, die ich in meiner gekauften Version jahrelang nutzen konnte.

...please fix the screen size issues.

It is simple and keeps history of operations.

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!

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.

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.
