Reviews for Scientific calculator plus 991

The app known as, 'Scientific Calculator', has been quite useful to me for my calculations. It has been of invaluable use to me ever since I downloaded it and I highly recommend it to anyone who needs an on-the-go scientific calculator for any reason!!

This app does substitute my Casio whenever it is not around me. It is true that it does more than a 30 euro calculator which is really impressive. Still physical buttons are physical buttons..., but excellent job on developing this very useful app. Thanks helps a lot.

great calculator app. the name starts with C when installed so you find it when looking through alphabetically sorted apps. there's no subscription. it's a one time purchase for removing ads and unlocking some more advanced features. simply fantastic

This app is very wonderful, great, nice and lovely, I'm a science student and this is helping me so well than a normal calculator. It's so impactful in studies and homeworks,brings out more unexpected options of your choice, and helps you to solve math, physics and chemistry questions, equations and brings out great topics in them that has not been thoughted in class to a higher level in your studies, Thank you so much for this app it is a great opportunity using this app.😁👍

i love this easily the best scientific calculator app in the store in my opinion it is the EXACT copy of the normal physical scientific calculator that i have and the paid features are only for the cosmetics! everything related to functionality is in the free version it makes me want to buy the paid version just to support this app

I love using this calculator. Quickly calculate complex equation. I started using this calculator and college. I even use it during exams where calculators were allowed. a decade later I still use this app. I prefer this calculator or my default phone calculator. plus it looks cool to pop out this app for a quick calculation. I don't even notice the adds. nothing ever pops up during my calcs.

I was considering a £100 physical calculator but tried this app instead. The £5 pro license offers comparable functionality at a fraction of the cost. Straightforward interface, reliable performance, and eliminates the need for expensive hardware. A practical, cost-effective solution for serious calculations. Recommended.

I liked the scientific calculator app it helps me more in my education & I can get the answers instantly & make so many questions in easily and catchy ways. I wanna need to Tnxs you for everything you have done to me. I just want to say keep it up & make progress & changes by improving your potential and addressing & and understanding academic skills. As a Suggestion I advise you to do better on other Subjects like physics,chemistry and etc... as much as possible to do.

Ever since I found this app, I haven't complained about not having the right tool for solving my tough calculations. For me it is a life saver for it can solve trigonometry, vectors, matrices, do unit conversion, and even draw graphs. There is no need for a physical calculator when you have this app on your phone. It's simply the best. I'm giving it the five stars it deserves. Highly recommended for students and professionals.

Excellent calculator. The only problem is it looks cluttered. Of course, by practicing its use, the problem will be normalized. But the suggestion is : please set the variable x, y or z in the first keyboard around +,- or 7,8,9. Its painful to use it by always tapping the alpha button.

Full disclosure, I did pay for premium -- premium is worth it for sure. This is a truly outstanding calculator app. It offers everything: fast numeric calculation, symbolic calculation, it has tons of equations and different calculation methods, it has a conversation function, it has graphing, it has programmability. A hidden gem, maybe the best calculator app (for engineers or mathy people) in the whole app store.

It is incredible for students and can help you even after school I bought the pro version I think it was a incredible price would have paid more for it if I knew how good and helpful it would be. Have contacted them for support pretty helpful. I wish they made the tutorial more visible possibly if you opened the app for the first time it asks you if you want to see a tutorial. I wish you could take a photo of a math question and have it be imported instead of writing it all out. Overall happy.

Very useful and quite advanced calculator for a phone. I even find myself using it more than my physical calculator as funny as it seems. Mainly because it can solve a simultaneous equation with 3 uknows, solve cubics...etc stuff that you have to pay $60 for on a physical one. All in all not "SUPER RIDICULOUSLY FANTASTIC" but it surely gets the job done

Does nearly everything (and then some) that I can think to ask a calculator to do. No intrusive ads, the UI is super customizable, it keeps history, and it has a handy lil' nugget I lucked upon: you can create shortcuts for often used conversions. Easily and quickly accessible on my homepage, I have mph ›› ft./s and mph ›› s/mi. (mild obsession with timing common activities). I have only one complaint - I hate the icon. Lol. Hardly counts. Best calculator though, and I have tried many others.

Best scientific calculator on android, and I've tried them all. I wish this exact app was on iOS. No other calculator has the right combination of UI, one line per computation, being able to sroll back through calculations, and functionality. Premium is a one time purchase that's absolutely worth it. The only other app that comes close is HP Prime, if you need to bring out the big guns and can deal with a heavier, clunkier app.

I love this app, it's rigorous in its performance. perfect for schooling, studying, learning, and of course for fun if you enjoy pure mathematics for its lore or as hobby. I rarely spend money on paying for premium apps, mainly because I don't use a whole lot of apps in general; but purchasing the premium for this one was definitely worth it, I bought I without a second thought. Even if you won't use it enough to justify buying it, the free version is plenty rigorous for what you need it for.

Excellent calculator. So far, it seems to have most, if not all of the functions that I need for at least high school math. Furthermore, I kind of use it as a notepad for numbers. While I leave many numerous mathematical problems on the calculator screen, I go on to the next one by just simply scrolling it down and calculate anew from that point on. Or I can take a single problem and break it down in screen separations, step by step. The one step not interfering with the other one,if so wanted.

First, the graphics are great! Makes the phone look like an actual calculator. Next, functions are grouped perfectly--easy, quick access. No glitches/screen freeze, etc. Put together very well. Thank you! This is the correct way you get people to buy a product--create a great app, DON'T put a bunch of annoying ads in their face. Once they see how amazing it is they WANT to contribute a few dollars. I would have paid more for this calculator ($10) -- it's SO much better than the others.

I have the paid version. This is my go-to app when I want a calculator with advanced features. But it needs better documentation, and it's missing a few features (or they're there, and I can't find them, such as adding and subtracting clock times took too long to figure out - didn't think of the °'" key). Also, sometimes I get wonky answers, such as when taking the square root of a mixed number that is input with the fraction key rather than the mixed number key. I would think both should work.

This app is an absolute lifesaver for scientific calculations. It offers advanced functions like trigonometry, matrices, and unit conversions, all in a sleek and user-friendly interface. The accuracy is spot-on, and it runs smoothly without lag. No need for a physical calculator, this app has it all. A must-have for students and professionals.
