Scientific Calculator Plus

excellent calculator that I tried but i hope you add option for resize number on main screen because it's small

Fantastic!

Not fan at all of the new layout. Edit: you didn't miss anything, the new layout looks on my phone exactly as on the screenshots: 3 lines for the display and squished input buttons. I personally prefer the old layout: 2 lines for the display and big square buttons. That's why I'll stick to version 5 for the moment. Thanks anyway, it's still a great app ????

Display and keyboard very readable thanks to good contrast and choice of colors (esp. Tavern theme). In general a solid, very usable set of features What a pity that absence of the expression editor prevents this from being one of the very best apps of its kind.

This continues to be my favorite scientific calculator application. It is splendidly well designed. It's operation is very intuitive and easy. The more I use it, the more I appreciate how well designed it is. One of the hallmarks of a superior software application is that, over time, the user comes to appreciate it more and more.

This can't do parentheses in equations? SO disappointed. It should be able to handle this equation: 6/2(2+1)=. All of my scientific calculators as well as realcalc allows you to use a parentheses this way. Calctastic does not. In fact, the parenthesis buttons are pretty useless. If you type (3+2) and type another number it gives you the answer of 5 and moves on to your next equation. Wow. Just, wow. A scientific calculator should be able to handle simply 9(5) and get 45. You may as well remove the parentheses from the program if they aren't going to work like every scientific calculator on the planet. Seriously.

Great app. But I really wish there was an option for showing hex, dec and bin at the same time on my phone. It has a 1080x1920 display after all. I can live with smaller digits and keyboard if necessary...

Best calculator I have seen so far - does everything I need and with a nice feel. Also have been missing RPN so much since I gave up on my old HP calculator many years ago - so easy to getting used to. And I can see that it has hundreds of features that I have not even touched upon yet - what a great tool ^_^

Works perfectly as designed,like a charm.Excellent UI+most elegant calc skins I have ever seen.Some suggestions:needs scientific function programming and graphing modes to be a full-featured calculator(matrix entry and linear-algebra features would be great).Also, onboard-installed help would be more convenient than the existing web-based.

Handles complex math very nicely. Go ahead, take sqrt(-4). It nonchalantly comes up with 2i.

Full-featured and good-looking calculator that supports RPN! Programming calculator is really useful, as are stack viewing and statistics operations on the stack.

Love the UX and UI, combined with great functionality. Best scientific calculator on the Play Store. Favourite theme is Monokai.

I use it in a daily basis at work. All the functions I need respond properly. No complaints, it just worth the money

Works like an RPN software calculator ought to work. Sharp graphics and number font. Variety of themes included are attractive, too. I wish the stack display was depth=4, but no stars off for that. Excellent tool.

One of the very few RPN calculators in the Play store that faithfully implements a solid stack system. It's even better than the HP 50g in the Play store. Keep up the awesome work!

A great calculator, especially in RPN mode - the best of the store. It would be nice to be able to use a smaller font, but that's nitpicking.

Efficient rpn calculator with lots of cool functions, conversions and constants. I paid more for apps based on such calculators as hp15c and HP prime. I also own physical 15c's, 42's, a 48, a 35s and a prime. However, I use Scientific Calculator Plus the most by far. Thanks for making this excellent calculator.

Very convenient calculator app. Wish it was possible to edit a previous expression instead of entering it again.

Finally a calculator that works like a real calculator.

Excellent calculator app in terms of functionality and usability. As an electrical engineer, I use it almost every day. Just 2 places I would like to see improvement. 1) exp and pi are very commonly used keys for engineers. Would be better if they could be placed on the bottom row. 2) It would be nice if user would be able to move cursor in an active expression to change or correct its variables and operations. Thanks!

All in one app: basic view, scientific view, programmer view. Easy to use but still very powerful. There may be calcs with more fancy feature or more configuration options, but this one is an excellent all-rounder for daily use.

Great calculator that supports complex numbers and doesn't ask for unnecessary permissions!

I've tested many and this is the best one! Not only full of functions but also most importantly user friendly! Just use the 'root' function and compare it with others you will know! After tested the free version I immediately bought this version. Plus it's only $0.99, way cheaper than the others.

One litte thing: in algebraic mode, enter this: 1 + i = x 3 = The result is 3+3i (correct!) but the expression display shows 1 + i x 3 = instead of (1 + i) x 3 = Please fix! UPDATE: thanks for reply! The spacing diference is too hard to notice IMO, it is better to add (..) around the complex numbers when it is required by algebra.

in a user interface. Customizable look, fine tuning of haptic feedback, and an easily scrollable history. I bought the upgrade not because I necessarily needed the features, but because I'm happy to support quality development. Thanks for a great app!

This is a very good and very useful scientific calculator app. I teach a number of science classes to entering college students, thus I need a good scientific calculator. This one gets the job done and is good looking too.

Love the UX and UI, combined with great functionality. This is the calculator to have on your brand new Google Pixel phone.

Best RPN calculator by far. I purchased this full version five minutes after using the free one. Excellent implementation of the kinds of unique features that a touch interface can bring to a calculator while still having a well-laid-out and responsive keyboard. Thanks! I'm very used to my HP 35s where the square root/squared key is the inverse of calctastic, x^2 is the shifted function. Some way of letting users customize their keyboard is probably much more complicated of a feature to set up than this non-programmer is aware of, though I'd get a lot of use out of it.

Needs scientific function programming and graphing modes to be a full-featured calculator.Would prefer onboard-installed help to the existing web-based.One note:Selecting stacks-display still retains the algebraic-entry;RPN-mode selection done in the settings-menu which makes an "enter" key to show up.This aspect somewhat confusing to the first-time user.

At least as good as the other RPN calculator apps I've tried, better than most, and the least expensive. Love the binary display in programmer mode. Would be helpful if mode could be switched by swiping left & right, and if all modes shared the same stack. Some AMOLED-friendly black and modern Material Design themes would also be nice.

I got this originally as a programmer's calculator, but was pleased to find that it also does all sorts of unit conversions. Looks great on large screens. New basic mode makes this the only calculator I need.

I finally found a modern feeling rpn calculator! I've tried everything on the store, this is the best so far! The flat Monokai theme looks great. I'd recommend including more material style flat themes like that in the free version, or making it the default theme in the pro. The other themes with the gradients and drop shadows don't follow material guidelines.

Really great calculator. Works almost exactly as you expect with minimal key strokes. As mentioned by other reviewers I'd also vote for automatic data transfer from programmer to scientific mode as at least an option.

I used the free standard CalcTastic product for a day. I was so impressed that I bought CalcTastic Plus the next day. I wanted to support the developer who did a great job, and responded promptly to the queries I posted. Thank you for a job well done.

I wish you make another one as a Financial Calculator.

Thank you well done.

Excellent product, can you remove icons from top right to menu...

I'm still waiting for your widget option but it is completely

Excellent caculator
