Rip off
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.

Molto buona.
App molto valida e con un CAS potente. Alcuni risultati possono essere semplificati meglio. Ad esempio perché mettere in un risultato 2tg(X/2)/(1-(tg(x/2))^2) , quando puoi scrivere tgx ?
Best calculator
It is simple and keeps history of operations.

Like 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!
