Calculator ∞ App Comentários

Recomendo!

Calculadora muito boa

Excelente calculadora

Calculadora que faz além do básico! Gráficos, cálculo, complexos e matrizes. Tudo de maneira simples e funcional!

Excelente App. Vale muito a pena. Parabéns aos desenvolvedores.

Muito boa e eficiente.

O melhor app

Simples - direta - fácil de usar

Usei bastante a parte estatística na faculdade. Já era muito simples naquela época. Na versão atual, está ainda mais poderosa. Falta apenas um tutorial para ensinar pessoas que não sabe mexer com as outras funções. Recomendo!

Estou usando esta calculadora a mais dês dois anos, simplesmente a melhor de todas já tentei usar outras mas esta ainda é a melhor. Parabéns ao desenvolvedor, recomendo a todos.

Muito bom!

O aplicativo é excelente e poucos se comparam a ele

É bom, sem dúvida! Muito útil. Há teclas que têm duas funções... como acionar uma, a que se quer, sem que acidentalmente se acione a outra, a que não se quer?

Boa calculadora, muitas funções e formas fracionárias de matemática.

They have Oxygen in here then Jennifer l. LaFlora

I have been using this in school, and I will continue to use this in school. This calculator has every function pretty much anyone could ever need and is a great help in my math and engineering classes. 10/10 would recommend

Ridiculous not worth a penny

The best calculator I ever use.

You need more calculation be easier to navigate screen.

A great quality calculator with many useful features. I have several scientific calculators and have tried many, many more. This is one of my go to favorites. Well worth having.

I’ve been using this app for probably 10 years now, and anything you would want out of a calculator, this app is more than capable of providing. This app beats out my overpriced Ti-nspire CX ANY day of the week for just a fraction of the price!

Wow, this calculator is strong and the customer service is practically instantaneous and thorough. I have piles of calculators and pages full of calculator and converter apps, I may no longer need to use the others. Anything one may be trying to do or teach as a mathematician is right here in one app. The unit converter is an amazing piece of software as well, far stronger than any of the others I’ve used. Cheers, keep up the great work.

Good

First it took me forever and a day to find the % sign. Then when I tried to subtract 20% from 74.50 it just kept doing a straight subtraction ie: 74.30. Needs a better UI Thank You

Good calculator that has a lot of functions and finally iPad support. Price is not that high and no ads! Great calculator for school algebra. I am impressed.

This thing can do next to everything. I have an upgraded version and it is a lifesaver. This thing gave me a way to check my work in Linear Algebra, Physics, Calculus 1 & 2, EE classes and more. Its mobile user interface far surpasses desmos’s and can do far more. The navigation takes a second to get used to, but the amount of functions are totally worth it. Must have for engineers, and even better on iPad

I paid for the upgrade but it doesn’t work…still says I don’t have Pro Access. No answer from support as of yet.

Best calculator I’ve used so far

love the calculator, but I bought queries for pictures and they were never given to me. I really have no time to do this work! I will probably be screwed in school tomorrow.

Helpful app

A great calculator and easy to use.

Really wish there were commas or spacing. 1,000,000 or 1 000 000 For examples

But when you pop up a “rate this app” when I’m trying to do something time critical, that pisses me off. Enjoy the 1 star.

I’m a licensed professional engineer designing critical components; and this is my go-to calculator! The features are impressive; and, it’s also a great tool for quick calculations when you don’t need all the bells and whistles! 5 stars!

Extremely good .

Review

Great!

Can't believe how cool this app is, I don't even know how much stuff you could do with it

It offers multiple functions and methods to use. It’s my go-to for calculations of all manners, be it simple or advanced solutions. And thank you for regularly fixing bugs and crashes.

This is worth the price!!!

Even after purchasing the lifetime upgrade it still reverts to the free app and won’t let you in to the upgraded calculator unless you jump through the hoops at the App Store.

The star off is for the (undeclared in the marketing) in-app purchase necessary to use a feature, namely the OCR/handwriting recognition. The charge isn’t even the issue, services cost money, but it shouldn’t be on potential customers to find this out after getting the paid app.

I just wanna see simple result like A+B-C=D without whole caculating process in handwriting mode to capture and paste to PDF excercise book(Flexil,Goodnotes,Notability,...) empty space not to occupy big space. So please make that option.

This calculator includes about everything that one would need to do math and logic. It also part of an ecosystem that includes a very comprehensive unit conversion calculator. As with any complex software, there’s a learning curve. But once completed, this app has been very helpful.

The pro version will remove the adds which are a hassle but you have to tell the program every time twice to log you into pro

It really has become my go to calculator. I really like it and recommend it.

This calculator is the best it lets you take pictures of the problem and it solves it for you

I used the free version for a year or so and bought pro when on sale. Best decision hah! The pro version of this calc can do basically anything. There are even some calculus level functions I’ve only ever seen on big TI calcs like the 89. I love that it can be a side app on the iPad Pro next to another app, and its size is adjustable without UI problems. Great for multitasking. Only criticism is that I can’t set it as my default calculator app (Apple problem). Also, could use a GUI update, feels a little 2013 when it comes to the graphical assets.

Some suggestions: Keys on the main keyboard page (flat, dark mode) have gray backgrounds witch is great, but what about the other extended keyboard pages?! Did the designers forget them?! Zero key is one of the most used keys on most calculators and so the zero key is one of the largest. But here, it’s not only the same size, but also is just above the menu key and you should be careful to not touch the menu key by mistake. The menu bar color (blue) is not matched with the overall dark design. Maybe a gray and darker color would be great. Even an auto hide option for menu bar would be awesome. Thanks for this great and powerful calculator!

They changed the UI on they latest release. It’s now awkward and hard to use.

I’ve been using this as one of my prime scientific calculators since high school. It is very feature rich and worth spending the money on. It does almost everything I have ever needed to do. Also graphs and solves equations for you.

Los números ahora son más pequeños que la versión anterior.

'Nuff said. It's the best. Get it. Period. Five year later, still best. Get it. Now.

I really liked this app, so I bought it, then they changed the ui and now I don't use it as much anymore

I haven’t used this calculator for a while so when I opened it up today I was surprised to see something that to me doesn’t even look like a calculator. I remember that it used to have a nice intuitive UI and now, not so much. I’ve been using scientific calculators since the 70’s and I’m getting too old to have to waste time digging through the manual to do the simplest calculations. If it ain’t broke, don’t fix it.

…and when there’s an interface that’s as crazy as this one is, there should be some guide or manual or tutorial that isn’t COMPLETE GARBAGE.

Infinity calculator. Covers many scientific functions and calculations. Ability to program and view multiple equations is nice

I have used HP calcs my entire career and so am having to unlearn RPN. I would rate it 5 stars if it had an RPN mode.

Love it

I recently switched to an iPhone from Android and was really missing my RealCalc scientific calculator from that platform. This one is a very good alternative- there’s a bunch of things I won’t need to use, but it does have everything I need for my engineering activities when I don’t have my normal scientific calculator on hand. The free version worked well but the ads were super annoying, full screen overlay in the middle of use. I could not find anything in the documentation or reviews that said the paid version would remove ads, so I took a gamble. I can confirm after buying the “lifetime” that the Infinity version of the app is ad-free. Hopefully this helps others that were on the fence about spending $5-7 on a scientific calculator app if it was confirmed ad-free.

this calculator is really good but i cannot graph trigonometric functions with it :/

Comming from an HP11c, this one has so much more to offer... With the caveat that to to do simple calculation requires switching to the simple calculator. The whole app is well done. Spending time learning the functionality pays off.

I’ve been using this app for years and haven’t needed a physical calculator for anything since. It does everything from simple arithmetic to complex integration.
