NCalc Scientific Calculator + Reviews

Geeze Apple. Now instead of losing the reviews, you’re losing their formatting! Update: I feel foolish I didn’t see the font size setting in Settings. My bad. Being lazy. Display font is plenty big now. 🤓👍 Somewhere along the lines I lost track of things and your reply, though a little tardy, brought Ncalc back to mind. It’s like discovering Ncalc again for the first time but THIS TIME I appreciate what I see better this time. So much so I ust bought the lifetime option (Thank you for not ONLY having subscriptions. Unless it’s a bookclub or tabloid, I don’t (and won’t) do subscriptions for 98% of the apps!) Excellent work! 5-Stars! ————- Algebra, Numbers, Boolean, etc., their associated text is uncomfortably small to read much of it. Still playing around with the test of the features. It is very configurable.

If you are looking for a piece of software that looks like your TI-84 Plus or Casio fx-9750GII/GIII or HP Prime is taped to your screen minus the graphing functions, then this is gonna get you there. There are other alternatives available, like those that truly mimic the TI-84 Plus CE. But, this is probably one of your best options as it doesn't take up the whole screen and has several types of calculator options. That's something your calculator can't do. Switching it's keyboard layout. But, that would require an edge to edge glass touchscreen. Please Apple, don't do it. They're expensive enough already.

I’ve tried couple of calculators but none of them were as good as NCalc Fx. Apple’s own calculator is just fine for day to day calculations but the main limitation is not having scientific functions (even some basic functions like square, square root are missing). So, I had to look for other calculators. I have been using this calculator for a couple of months and I’m really enjoying this calculator. $2.99 lifetime purchase is just awesome. Don’t get me wrong. The free version was as good as the paid version. I just don’t want watching ads that’s why I purchased the lifetime subscription. Really worth the money. ALL IN ONE PACKAGE.

Is there an option to make the outputs order of a polynomial be in descending order from left to right?

For example,
If my input is: 1 / (x+2)^3

The current output is:
1 / (8 + 12x + 6x^2 + x^3)

I would like the output to be:
1 / (x^3 + 6x^2 + 12x + 8)

Edit:

Thanks for your feedback for my original post.

Here is some more feedback that would be amazing in future updates!

1) Double tap a previous entry/answer to paste it into the current entry line.

2) Work on the CAS simplifying method:

For example:
If I take the derivative of a function, it isn't always simplified down entirely.

Input: [2*sqrt(2)*(X^3)] / (X^4)

Current Output: [2*sqrt(2)*(X^3)] / (X^4)

Preferred Output: 2*sqrt(2)*X

3)When something is raised to a power, creating a toggle to leave the powers as fractions, and not simplifying it with a nth root.
For example:

Input: [X^(5/2)] * [X^(2)]

Current Output: sqrt(X^9)

Preferred Output: X^(9/2)

Alternative output:
Auto pulling out whole powers: X^4*sqrt(X)

This calculator is legendary BTW.

Having purchased and tested many calculator apps, this one is by far the best for my needs. It takes a little to get used to, but once you do, it is extremely powerful. It is responsive on input, has a nice visual representation of the input and output, and the ability to edit historical calculations easily is needed indispensable for me. I hope they keep it this easy to use as my previous calculator was just as good but when they did an update they ruined the ease of use. So far this one is well worth the money.

This calculator is a pleasure to use. I have tried a lot out there, and I’ve concluded this is the best overalls. It feels natural and intuitive. The buttons are well placed, well displayed and responsive. The array of math functions is vast and highly findable, probably the biggest challenge in a modern Calc app. The customizable interface was an added bonus. This team are true calculator nerds! I like the separate graphing screen because you can do much more than you could with it. Just an overall pleasure to use

This calculator has great precision and lots of features, definitely worth the price for the premium version. I wish it was smarter with the display of the results. In SCI mode no need to display * 10^0, if decimals are all 0 could be avoided. In FIX mode if the number is very large it could also be converted to SCI. It would be good to have an option to skip the list of divisors when you press ‘Detail’ on the LCD, it takes very long time for large numbers and I saw it crashing a little after. The 3 digit comma for the decimal part should start at the dot, do not show in Details 0.8,234,567,567…

I’ve been looking for a good calculator app for my iPad, and NCalcScientificCalculator tops off all the other apps I’ve tried. The design is sleek and set like a real life scientific calculator. My favorite feature is tapping in the answer, and NCalcScientificCalculator shows what my answer is like in decimal form, mixed fractions, etc.

I know it may be complex, but I’m really hoping the same developers could make a graphing calculator too. I am so impressed and hope for more accomplishments for this group. Job well done.

This calculator has everything that you could need just to make a simple calculation. The fact that it has unit conversion makes it all the better. Never thought a simple calculator could seriously get this advanced to where you use it for every calculation in your day to day life.

It took me about thirty minutes to figure out most of the buttons, and let me just say, it made my Algebra 2 homework go WAY faster.( don’t worry, I had my teachers permission). NCalcScientificCalculator is way smarter then the calculator app that automatically comes on your iPhone. You can actually solve problems. I’ve only had it half a day and already love it.

I can’t tell you how much money I have spent on other apps I thought would do the job only to find out I was wrong. This calculator does everything I need it to and so much more. I use it for everything from checkbook to Calculus. The GUI is amazing and the calculator is mind blowing. Well done Dev, thank you for such an amazing calculator!!!

At first this calculator is capable of so much that it is rather daunting. You end up hunting for, say, the % key, jumping from one keyboard to another. But there are loads of help pages and after a while you will find your way around, and decide that it is the only calculator you will ever need. And indeed, it is. I love it.

My main complaint is with NCalcScientificCalculator you can't inpupt a decimal point using the numeric keypad (on the right side) on my Mac's keyboard. At times, I can't use my keyboard at all to input numbers or certain functions ( - * / enter). When this happens, I quit NCalcScientificCalculator and start over and then I have access to the numbers and certain functions on my keyboard.

This calculator has a host of fantastic features and options (too many to list), great themes, and an amazingly thorough help file. It has replaced Mathway for me...and at a fraction of the price. I've tried them all, and this is the absolute best all-around calc I've found. This one's a no-brainer, people.

This is honestly the best calculator app I have. I purchased the premium (for life and only $3) and I love it! Even if you don’t have premium it gives you everything you need. I used it throughout middle school, and I am still using it. Definitely recommend!

It operates as one would expect. If you move between the real one and NCalcScientificCalculator , one hardly notices the difference unless using the extensions in NCalcScientificCalculator . Outstanding calculator. It has replaced my other calc apps in everyday use.

I have probably 10 calculators on my phone, though 9 of them get any use since NCalcScientificCalculator. Well thought out, nice and familiar UI, extremely customizable. Wish it allowed for user defined schemes, but that is just a nice to have. Well done team!

I went through all the top scientific calculators. Most are missing the most basic keys, such as 1/x or EE, but cluttered up with useless functions. Well designed, intuitive for the most part. Help is clear where needed.

By far my favorite calculator app. As a machinist I use it daily. It’s easier to use than the one on my phone and has all the conversion info I will ever need. Everything is intuitive enough for me that there wasn’t much of a learning curve

I’ve been using an HP 48 emulator on my phone so long I didn’t think I could ever switch to another calculator, but this is so easy to use, so beautiful, so well typeset, and so clear it’s become the only calculator I want to use

Love this calculator, it’s not Wolfram Mathematica, but it’s vastly more useful than most of the other choices.

Improvement points needed.
More decimal precision, at least up to 32 digits.
Base conversion (at minimum binary up to hexadecimal bases).
Better Copy&Paste. Add the ability to select formulas & save to a selectable Save & retrieval list. Add the ability to select numbers from the HISTORY log file and add them to a save list.

Very nice calculator which long time have been waited for it!
Thank you for your great software

This is one of the best scientific calculator in NCalcScientificCalculator Store. It’s worth every penny. Great job.

Very nice calculator. If you are used with Casio classwiz models it is very similar.

Please

V v v good work thanks developer may u live long

Loved NCalcScientificCalculator !!

Es maravillosa esta aplicación, recomendada al 100%, a penas pueda comprare su versión full sin pensarlo

Quá đỉnh luôn ấy ạaa

Giao diện đẹp, sử dụng tốt. Có thể thay thế được máy tính bỏ túi

Sử dụng tốt. Mọi người có thể sử dụng thay máy tính cầm tay

After I changed some parameters in one equation, the result went wrongly which is really inconvenient bc I have to reinput my equation and go over the process again.So confusing.

The only app I missed when I switched from Android to iOS is RealCalc, which is only available on the Android store. I am very glad that I finally found this “emulator” sci-calc for iOS. To the developer: Thank you so much for creating this important and unique emulator and making it available for free. I really appreciate your work!

This is one of the best apps i have found till now. Appreciated your hard work.
