Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.

Don't hesitate to contact us if you have any questions or concerns.

4 ★An update just to change the name of the app?

5 ★Very nice thank you again

5 ★Very nice job.

5 ★From five stars to one star. Get rid of it ASAP !!! Update: Back to FIVE stars after removing the obnoxious splash screen. 👍✌😉

5 ★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.

5 ★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.

5 ★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.

5 ★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 !!!!

5 ★Love the app, HATE the new icon.

3 ★mismatched keyboard codes

5 ★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.

4 ★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
