Totally worth the money Totally worth the moneyI've had this app since September 2014, and I turn to it constantly. It is so good, I deleted all the other calculators on my phone. I still have my 41CX, but I use this version much more often. I feel it was totally worth the money. My current complaint is that it's taking over 1GB on my phone. Why? The app is about 130MB, so why does it need so much more for data and documentation? I want to minimize this. Please tell me how, or implement it. My phone is only 16GB, and I can't have the app taking up so much of it.

So powerful I may never fully plumb the depths of this app So powerful I may never fully plumb the depths of this appMarch 2 2015: Thanks for the update. I'd give this app 6 stars if I could. ------ This is the most amazing app I've ever seen. I bought it years ago, thinking I merely had a powerful calculator. Only recently did I discover the huge number of FREE plug-in modules, which turn the i41CX+ into any number of specialty calculators. For example, if you 1) put the FINANCE module into one of the 4 open slots, 2) set it to the FINANCE overlay and 3) type XEQ [ALPHA KEY] MONEY [ALPHA KEY], you will have yourself a financial calculator so powerful it'll bring tears to your eyes. This one example only scratches the surface of what you can do with this app There is so much more to this app module-wise, but on top of that it has programmability and CAS. You can view a printer tape and email results. The question is, what can this calculator NOT do? Downloading the modules is how you tap into the multitude of abilities this app has, then follow the 3 steps above for the particular calculator you want the i41CX+ to become. . I recommend getting the Mini Manual to help you get going. It's a free download, easily found in any search engine. Footnote: about a month ago, I did buy a dedicated Financial calculator for $8 in the App Store. As good as it is, it turned out I wasted that $8, since what I described above far and away surpasses it. I had questions which the developer promptly responded to, that's always a huge plus for me.
