Still the best

I’ve been using Duy Tran’s calculator apps for a few years now. Absolutely fantastic apps. They work in a completely familiar way and can sit comfortably on Mac desktop, iPadOS and iPhone. Great to have proper scientific calculators on hand without needing a separate device!

Outstanding calculator

So easy to enter problems

Hervorragend

Mit Abstand der beste Taschenrechner für die Hosentasche!

Ich nutze die App seit 3 Jahren gerne und sie ist nach jedem Update sogar noch besser geworden. Die Vollversion lohnt sich, der Entwickler gibt sich wirklich Mühe und das merkt man auch.

Ein Muss für die Baustelle oder im Ingenieursstudium. Schnell, übersichtlich und viele Design Optionen. Teilweise nutze ich die App beim Lernen, wegen den praktischen Grafiken, sogar lieber als meinen Uni Taschenrechner.

I’m a seasoned electrical engineer having spent my career using RPN. RPN is efficient for simple calculations but the breadth of capability using NCALC has me excited to learn other ways to solve circuit issues. There is nothing the tool can’t conquer with some work and devotion. I’ve owned NCALC for a few years and hoped a few YouTube videos would suffice. I was wrong. Fortunately, the manual is excellent and as I take on more tasks to uncover, the possibilities keep revealing themselves. It’s very well done and that it works on so many Apple devices allows the circumstances of life to not keep from reaching for it. Thanks to the design and quality team for making this tool available.

Simply put, the best calculator I’ve ever had!

I was always fascinated by what calculators could offer, and even though I had in the past some quite capable ones, NCalc is just the best of them all, the simplest and most intuitive to use, and the one with the most attention to detail on its user interface I’ve seen so far!

Pretty good

I mean, this calculator isn’t perfect, but compared to the other ones(specifically the black & orange ones that are filled with ad breaks), it’s pretty good, really helps in match class :D

Button Not Updates

Please update the interface of button as natural keyboard (up,down,left,right buttons) as updated in android version. Also provide update as soon as updated on android version. Other is fine I had purchased premium and praises this software developer make a best product. If updated 5 star now only3.

It s ok to use it

Best iPhone calculator

Does everything I need and is easy to use.

Good calculator with a huge minor problem

The calculator itself is fine. The problem is the ads that displayed there. When i play a video or a music in the background while using the calculator, the ads stop my music or video from playing.

I tried using it offline and it was fine because no ads showed up. I don't know if the ads that you place there are videos by nature or what but it's like that in other apps.

Second problem is, there are sexual ads that sometimes appear. I'm not interested in those things. Please fix this. There is no need to have adds on a calculator. You can block many features to make proper to but the full app which is fine but the ads are repulsive

It helped me so much with my English assignment!! So good!

So basically I had a task to write a story about a bear, and I wanted to write about Winnie the Pooh. I planned this splendid story about how Winnie needed honey and then asked Piglet for some. It the thing was, I did not know how to spell delishous! Well, I downloaded this calculator and it helped me spell it, and even gave me tips on how to improve my story! Thanks to it, I now know that delishous is spelled with an sh and not a c, like I previously though. This app is super ⭐️⭐️⭐️⭐️⭐️

It’s good, but there needs to be a fix.

The “*10^n” part beyond 10^10^20 needs to be inside the exponent, not outside.

Good app but I wish there was dark mode icon

I like this app, but I wish there was a dark mode icon
