ajpollin,
Overall very good calculator app
Edit: ⭐️ I’m downgrading to 1 star. Even after giving a 5-star review under duress, I continue to receive pop up notices asking for a 5-star review.
Edit: ⭐️⭐️⭐️ I have given this 5 stars only because it is incredibly obnoxious to have to have to click away the pop up asking for a 5-star review (see below) every other time I open the app. I paid for premium so I wouldn’t have to deal with distractions from using the calculator when I need it. The calculator itself is excellent. It’s too bad the developers marketing strategy isn’t. Original review: Overall NCalc is a very good calculator app, especially if you are used to Casio’s scientific calculator layout. I’m giving it 4 stars rather than 5 for two reasons. First, the layout of the arrow buttons doesn’t match the Casio, and irrespective of that, it’s just not very intuitive. The up and down buttons are side-by-side instead of stacked, so I really have to pay extra attention when using them. It’s a little thing, but it’s distracting and a bit irritating. Second is the fact that even with the paid version, half the time I open the app it’s to a pop up asking for a 5-star rating, which I have to close before I can use the calculator. It’s almost as obnoxious as the ads were in the free version. I understand why the developers want (good) ratings, but they should be incentivizing users to willingly rate rather than punishing us for not rating.

Reviewerxx,
A solid scientific calculator
Just buy it if you're in a field like math or engineering and you need a solid calculator.
Here's what I like:
(1) It handles symbolic manipulations very well
(2) Reliable outputs and stable performance
(3) Lots of useful mathematical functions
(4) Layout and buttons work exactly like a regular calculator, and some people may not like that, but I like the simplicity
Here's what I don't like:
(1) The icon is incomprehensive. It's way too busy looking. I have it on my dock and it's annoying me everyday.
(2) Cannot use finger to move cursor around. You can tap on a location, but it's not accurate enough to get you to where you need in the expression. I want to be able to use the magnifier to move around. Currently, I have to use either the arrow keys or external keyboard to move around the expression, which is fine since that's how regular calculators work. But I think it would be more convenient to use the magnifier.
(3) For some weird reason, why you start up the app, the edit screen will resume with the last expression you worked out. That means when you open the app, and you start typing in a new expression, it will add to the last expression rather than start a new expression. It's really annoying, because I have to exit the previous expression before I can type a new calculation every time I open the app.

Eriptron,
Font text for text associated with the 8 green buttons
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.
Elvis-n-Max,
Great app
I love this calc been using for years it has a high tech look and I paid for the ad free version. It looks great and works great on my I pad pro. Split screen and slide over works very well. My only complaint I wish there was a way to display numbers in a column fashion. When adding long lists of numbers they disappear off the right of the screen since they populate left to right. Of course you can use the arrows to slide the numbers back into view. But that is slow. I’d like to see a wrapping function, or better yet the ability to tally numbers in a vertical column as you would by hand on paper and it would be neat to see a line under this column and the total sum as you would do and see on paper.
Caleb Nathaniel,
It does every calculation I could possibly ask of it.
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.
Tanjid Ahmed,
This is just an awesome calculator.
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.

Perfect for a casio loving engineer
I grew up using Casio scientific calculators mostly the fx-991ES during engineering school. And let me tell you that this app was the perfect choice for me. After using it a couple of days with the ads, it was a no brainer to pay the lifetime subscription. The only difference I feel from using a real Casio is missing the feel of the keys. However having not to carry an extra device and being able to copy/paste/edit history adds a convenience that is better IMO. First ever app I paid real money for and I do not regret it at all
Cody2185,
Polynomial Descending Order?
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.

Excellent Calculator
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.
Mist02,
Impressive
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…
