[2012-11-07] Shawn: Great App Works just like a real HP 15c. No issues. |
|
[2012-10-31] mikeisgoodforyou: I like it Works just like the original except faster. Does what it says. |
|
[2012-10-30] RMB: Not worth the price I had an HP 41 emulator on my iphone 3gs. Same price. Even with the much smaller iphone screen that app is superior in every way to this one. There is almost no feedback to key presses with this app. No click, no key movement only a very slight darkening of the key. This app is definitely not worth 10 bucks. . |
|
[2012-10-24] Bruce: Just like the original My original HP15C is finally showing signs of old age, so it's good to have something to replace it with. It's on my Galaxy SII phone and Galaxy 10.1 tablet. I've tested the high-power functions with no surprises in the results. |
|
[2012-10-20] Jerry: HP 15c Great app. Programmable, faster than the original. I love it. I hate algebraic calculators, always lose numbers and want to throw them away. |
|
[2012-10-19] ntamm3: Excellent Excellent! |
|
[2012-10-09] Capt. Haddock: P15c A very useful and reliable app with good documentation |
|
[2012-10-04] Christopher: Great app. But...... I would have given this app. 5 stars, but the graphics are just to far off (i.e. power of as well as many other buttons contains a carat instead of the graphic that actually belongs there). Also, complex number functions etc., are not working. Other than that it looks great. Dev., could you PLEASE issue a fix? Reminder, this is NOT a free application!! |
|
[2012-10-03] Jim: I love this app! Just like my trusty 15c. |
|
[2012-09-19] Jorge: Excellent! Just line the original!!! |
|
[2012-09-19] Jeffry: Controls Eng. HP RPN calculators have always been my favorite and now I have one on my phone that looks and works just like one. |
|
[2012-09-12] Donald: 15c calculator Awesome app, works well. |
|
[2012-09-09] Fr Kevin: Superb! I loved my HP-15c and this is a great emulator! |
|
[2012-09-05] Ken: HP15c Great product |
|
[2012-09-02] xxloverxx: Appalling Unacceptable graphics on the Nexus 7. Half of the screen is wasted! On a pixellated background, might I add. |
|
[2012-08-30] Julian: Good simulator for HP15C Very pleased with this HP15C simulator. I use it interchangeably with my actual HP15C which has been going strong for 25 years. Would prefer the screen to flip either side rather than in just one direction. |
|
[2012-08-20] JT: True to my 15C This emulator does everything I have come to expect of my "real" 15C. |
|
[2012-08-17] Art: HP 15C Better than ever was |
|
[2012-08-17] Gregory: Love this app! |
|
[2012-08-12] Robert: Awful This is definitely NOT the only HP 15c emulator for Android; however it is probably the worst. The graphics are done ineptly and scale very poorly on larger screens. It looks absolutely atrocious on my tablets at both 1280x800 and 1920x1200. Moreover, key labels use normal characters instead of graphics, so any keys that use special symbols look nothing like the keys on a real 15c. The esthetics aside, the biggest problem with this app is that it doesn't support any functions that require a key to be held down. This is needed, for instance, to check the available memory, where you would press "g" and then hold down the "mem" key or, far more importantly, to view the imaginary part of complex numbers by holding down the "(i)" key. Instead of allowing you to hold down those keys and displaying the results for as long as the keys are held down (which is what a real 15c does), this app only allows you to tap the keys and displays the results for only a tiny fraction of a second, far too short to make out anything. Essentially, you cannot use complex numbers, which renders this app completely useless. |
|
[2012-08-01] Pabs: Great HP15c emulator Almost like the original! Better get a 5-inch or larger display as the touch input is tricky with ordinary, palm-sized Androids. |
|
[2012-07-31] grathganor: great remake I own an original hp 15c. while it is almost always with me, this is my go to replacement. |
|
[2012-07-25] dex: An old friend My 15C broke many years ago. It is wonderful to have it back. |
|
[2012-07-23] mark: Great emulator Great emulator of one of the best calculators ever. Makes me smile everytime I use it! |
|
[2012-07-18] Glen: Okay Works as advertised ... But it needs to stop asking me to rate it. |
|
[2012-06-26] Kent: Still needs a little more work Imperfect score due to the fact that the buttons did not adjust to my generic 7" tablet. |
|
[2012-06-19] Darin: Great Needs a bit more delay showing f ( i) |
|
[2012-06-12] JD: Thanks Thanks |
|
[2012-06-07] 4MLA1FN: very good hp15c is the greatest calculator. i love having a facsimile on my gnex. |
|
[2012-05-22] Michael: works exactly like my physical 15C |
|
[2012-05-19] David: HP15C Best RP 15C I've used on a Smartphone |
|
[2012-05-14] Angel Porfirio: Excellent Recommended to install it. |
|
[2012-04-28] Reint: really like HP15C can not calc without it I'm using the real HP15C since 28 years. having this on my android phones lets me calculate without thinking where the buttons are..or rethink how to calc without RPN. Absolutely a great app. Reint |
|
[2012-04-22] John: Great Simulation Only complaint, pause in programming is way too short. Using stop instead. |
|
[2012-04-02] kljoki mlitavi mlitic klimavi: Small graphics ! Cons: (1) The keys almost unvisible and unreadable on 4 inch screen (640x800). (2) Display numbers to thin and too small. (3) It does not use the full screen. (*) Dear developer ... take a look at "go15c" graphics. My glasses dioptry is +1.75, calc is almost useless for me. |
|
[2012-03-24] the 4/1/2012 : Seems to be a faithful reproduction I've used it for a while and have no complaints. Its refreshing that an app can work without requesting any extra privileges. |
|
[2012-03-22] Mike P.: Love it! just like my old 15c |
|
[2012-03-22] mamboze: Minimal changes to make this an outstanding app The 15c is a good emulation of the HP 15c which seems to have identical functionality to the original. It could bear some improvement tho. As other reviewers have noted, the key labels are simply too small, this detracts from usability as well as appearance . I have an HP 15c and the key labels occupy nearly the entire top of the keys. Unfortunately, the developer has chosen to use the existing system font for labeling the keys and other text. This is a design mistake. The key labels and other text should be bit mapped to ensure fidelity to the original design. I cannot see why this was not done, except for reasons of easy implementation. Not good for an app which is in the higher cost range. Moreover, in the original HP 15c the 0-9 digits occupy the width of the display screen. In the 15c, the 10 digits are unnecessarily small and occupy less than half the available screen space. Why is this so? Again, a curious design decision. I have written a rather lengthy review because I think 15c is mostly well done and I like the convenience of having a familiar and very powerful calculator on my Galaxy S2. It just needs some finishing touches to make it an outstanding app. |
|
[2012-03-19] Carlo: Good emulator for my HP 15C. An improvement would be to have standard math operator symbols, eg ÷ instead of /. |
|
[2012-03-04] Matt: Great App! This one of the best HP-15 apps. Downloaded the manual and have tested various functions and they work! All it needs is the back of calc graphic... |
|
[2012-03-04] Simon: Good Like this app. Very realistic. |
|
[2012-02-25] steveo: Just OK Graphics are a little small; I can't enter complex numbers using the (i) & I functions. Everything else is great. |
|
[2012-02-06] AardWurk: Great app! Now that HP has the 15c back in limited edition, this makes a great traveling tool. |
|
[2012-02-05] Steve: Great RPN Calculator This app functions very well as a RPN calculator, but it would be just a bit more awesome if it could display and function in both portrait as well as landscape orientation. It's just a little inconvenient that it works only in landscape mode and I often have to flip/rotate my device just to use this application. On my superamoled HD screen (Samsung Galaxy Nexus), the calculator keys seem a bit too wide when the calculator face is displayed in landscape mode. |
|
[2012-01-17] Philip: Just great! Love it! |
|
[2012-01-17] charlie: Tiny tiny tiny I love the old HP functionality but have to agree with others complaining about the font size. For me its Betty difficult to tell the plus sign from the divide sign. It slows me down. Just increase the font guys and change the classic division sign to a slash |
|
[2012-01-08] Edward: Easy to read clear keyboard does more than I'll ever need. |
|
[2012-01-07] Mark: Okay, but needs some work (for tablet at least) On my Galaxy tablet, the calculator looks too "spread out", and the display is ridiculously long. The X<>Y key is mislabeled, and the clear prefix command (to show the full number of digits calculated) gives a super-quick look, too fast to be of use. Also the menu command (Android) doesn't work, which I suspect should enable me to enable key clicks and save calculator state, in any event I have no access to key clicks or save state. I'm very glad to see the developer working on a tablet version, but would recommend for update: don't spread this out over the full size of a 10" tablet screen. Make the aesthetics a bit better, and work on the features noted above. Looking forward to updates! |
|
[2011-12-22] Darren: Great : A nice job on a classic calculator |
|
[2011-12-22] cnac: Hp calculator The +,-,*,/ symbols are too small to read on a smart phone. Can the key symbils be made larger |
|
[2011-12-17] astroglenn: Nice job Very nice reproduction of a classic! |
|
[2011-12-14] Joe: Okay One of the great features of HP calculators is the positive button press feedback. The emulator is lacking in that regard. Maybe with an update. . . |
|
[2011-12-08] Tim: I've always loved the hp-15c Would be nice to have the vibrate feedback when pressing buttons. |
|
[2011-11-28] Sotos: Perfect! For those of us hooked on RPN logic, this is a fantastic application. Good work! |
|
[2011-11-22] Daryn: Great Great to see a 15c, key formatting is fixed on HTC magic. |
|
[2011-11-03] Andrew: A good emulator of the HP15c, probs with sequences like "f PREFIX" to view full precision & to view Mem allocation, neither stay long enough to see |
|
[2011-10-02] Thomas: OK I wish buttons and typeset would be a bit bigger, I find legibility borderline. I also really miss that I can see values of the entire stack. |
|
[2011-08-25] nocklebeast: It's awesome. The only thing it lacks is the keyboard feel of the original. |
|
[2011-08-18] Kjell Jarle: I like it. Wishes: Larger digits and let ON button actually terminate app. |
|
[2011-08-15] T: Text too small Text is way too small to be used. I cannot recommend this program until it is fixed. |
|
[2011-08-14] Dave: Poor display Functionally it works like thee calculator but the display is nothing close. The numbers are too small and the font is proportional (goofy looking) |
|
[2011-08-03] D: Works like the original at a fraction of the cost. |
|
[2011-07-29] Robert: Great emulation Very pleased! |
|
[2011-07-11] mjc: They promptly fixed problems I found. So far, appears good. |
|
[2011-07-11] Bill: Beautiful work. I would like it better if the symbols on the virtual keys were a bit larger. I have a large display with small pixels. |
|
[2011-07-11] Angus: ExACTly like the real thing. My phone just became a REAL calculator...just amazing.... |
|
[2011-06-26] Matt: This one of the best HP-15 apps. Downloaded the manual and have tested various functions and they work! All it needs is the back of calc graphic... |
|
[2011-06-21] Jorge: Just line the original!!! |
|
[2011-06-07] Nelis: Graphics too small, barely readible. If you know the HP15 well it might be ok, but for new user it is a struggle to locate the keys. I prefer droid48. |
|
[2011-05-05] Mark: great HP15C emulation I'm very happy with this. Used a HP15C as my primary calculator for years. There is a minor bug on the T-mobile G2 in that the keyclick doesn't work. Still I was happy to pay $10 for this app. |
|
[2011-05-01] John: This app should have had a free trial version for non-legacy hp 15C users to be able to try. Works good I guess, but I much prefer the Free42 calc. |
|
[2011-04-23] Tom: So far I like it. Only thing I would change is increase the point size of the yellow and blue function letters. I have not tested all functions yet. |
|
[2011-04-11] Tony: Good calculator! But for a $10 app, you should get help built in (i.e. the manual), and there should be some options, e.g. enabling haptic feedback. |
|
[2011-04-01] Daryn: Great to see a 15c, key formatting is fixed on HTC magic. |
