Crash on startup As of version 2, the program crashes on startup with an "out of memory" error on my Xperia X10i (the last working version was 1.5). I'm hoping this will be fixed soon.

more accurate than original HP15c ? I only just tried this out, on a Samsung tablet running Android 4.2.2. I have an original HP 15c and was comparing it to this app. I enter radians mode (fn.g-RAD), then enter pi (fn.g-pi) symbol, then hit SIN. The original calculator says -4.100 E-10 but the app says 0.000 E 00 which is technically the correct answer, although different from the slightly-inaccurate HP15c. On my Samsung Galaxy Ace (smaller screen) the blue and yellow function text on each key is slightly hard to read (looks like a larger bitmap downscaled without antialiasing, so some pixels are omitted). If I had a choice I would make the keyboard background darker for higher contrast. My real 15c has a darker background keyboard / case color (more black than grey). ...also, thank you for not requiring network access permissions, as some competing 15c apps do.

Adaptive Simpson's Method and DSE/ISG I like the layout of the Andro15C very much but I would recommend a future release incorporate the Romberg integration method (or even Gaussian Quadrature) instead of Adaptive Simpson's. The very first integral I tried to solve was unsuccessful. It will not solve Vardi's integral: ln(ln(tan(x))) dx from pi/4 to pi/2. Jeff K

Excellent ! The most accurate 15C emulation for Android. Perfect graphics and functionality. Well done dev, thank you for making this available for us all !

Simply just right !!! I've tried loads of scientific calculators. Either the key responses are poor or the graphics deficient or a really awkward method of accessing trig functions.. Not this calculator; it just works !!!!

Awesome 15c emulation, like all of Elvis' Voyager series implementations (please check my other reviews). Note that if you can't find the menu button, you can still access the app menu by touching the numeric display (noticed this on Lollipop, YMMV). This lets you access special functions to adjust the display, calculator speed, saving and loading program memory, etc.

Nice implementation Elvis has put together a nice clone of the original. For me, startup always takes a couple of seconds, FYI, but no star deductions just for that. You'll be happy with the app.

New Icon Love the app, HATE the new icon.

Keys vibrate nicely. Looks real. Small tweak: A small improvement would be, if press-and-hold-fPREFIX, then keep displaying all digits while button is held down, like the real 15C [edit: holy crap, updated and now it's perfect]. This app is the one I recommend for a reasonable price.

Nice implementation as an original HP 15C Owner. Elvis has put together a nice clone of the original, and he releases updates as needed. For me, startup always takes a couple of seconds, FYI, but no star deductions just for that. You'll be happy with the app.

Excellent value Except for perhaps the superb yet pricey HP app, this is about the best emulation or simulation of the 15c I have tried. It looks good, it works, it is faster and works with higher internal precision so programs run better, and it has the excellent feature of storing and retrieving the calculator state so program memory can be preserved. The free version is an eyesore with the ill-positioned display and ads. Serious fans of the 15c will not regret parting with a few bucks for this one.
