Scientific Calculator Pro

This calculator has the most elegant design I've come across in such an app. Best of all is its super easy to use and very accessible esp. if one frequently works with complex numbers. Highly recommended! EDIT Devs can you please have an engineer option for i /j at the front of the imaginary number, and also a way to remove the underline when entering digits . Thanks!!

Beautiful interface, many functions including number base conversions. The best calculator out there. As other stated, it needs a detailed help feature and the ability copy and paste results.

Every thing I need for calculation in one handy package.

I need to do fractional operations like 1/2+1=3/2 not using decimal point answers

This app is great, especially when using complex numbers in polar/rectangular form, in a very similar way to graphing calculators (without the graph bit, of course). It is intuitive and quick to use. However, it is lacking a manual/instruction set file avaliable offline, inside the app, to make it perfect. Other than that, it deserves 5 stars.

This has been my favorite functional calculator for some time. After using it for over a year I am now forced to come and complain. The use of memory, history or complete computations is made impossible by its never ceasing crashes. My attempts to stop the issue have been fruitless. It feels good at the start, but after awhile you notice the crashes are not accidental back clicks.

I gave the free version 1 star and this paid version 5 stars. The latest "free" version permissions give it acess to just about all your personal data. This calculator is the best one I've found, bar none, but no app is worth giving all your personal info. This paid version asks for no permissions at all so spend a couple of bucks and just get it... You won't be sorry.

I don't know what are the premium features but I'm very happy with the free version

As many others, I found this app (one of) the best(s). It would be nice if digit grouping would also work when I enter the equations, not only at the result. And if I could navigate in the equation by tapping on the screen (beside the existing arrows), that would be a wonder. But these are less important things, the app is still very cool and useful.

As far as being a scientific calculator is concerned, this app is the best I've used. Lots of functionality; far more than I will likely need. The only issue is that, if exited without quitting (SHIFT + C), it will crash. If that issue was fixed, this would easily be a 5-star app.

I would love to give this app a 5-star rating, however it is constantly crashing whenever I try to open it. I can usually get it to work, but it sadly crashes about 50% of the time when I got to open it. Once it's open, it works great.

Why is the free version getting updated before the one that helps the development of the apps? This pro version too should be updated with new and different additions to version 1.6.3. I think we deserve some special treatment. You owe us that, Remember?

Actually it's a great calc, but I am not going to keep flipping my tablet over in order to use it. I did finally get the screen rotation lock to prevent the apps desire to flip over on start. Well, I didn't actually do anything, except to try it one last time days later and it worked. Now up is where it belongs, and the device buttons are in no danger of being pushed while attempting to hold the device.

This calc works great. But, it seems to crash every other time I launch it (Pro version). It seems to have trouble pulling up the memory of what was done earlier or something like that.

Needs no permissions and does everything I have ever needed it to do. Avoid the free version like the plague because it accesses your contact info. For a couple of bucks this paid version is worth it.

The option to view multiple lines like on a ti83 or ti89. I would love to be able to throw away my Texas instruments overpriced garbage.

The free version of the calculator has been updated numerous times since Jan 2015. The pro version has not. It crashes constantly. Otherwise a very good calculator.

Buy another app. The app crashes after being partially unloaded in the background by the os. I've been waiting for months for the devs to fix. Don't reward them for poor quality.

It always crash when I do this eq tan^-1 (-i)

I have tried many calculators. I think that this calculator is one of the best in terms of simplicity and functionality. It deserves more than five stars, because it does what it has to do. Many thanks to the creator of this calculator. However, please add the user manual, because when I try to convert polar form of the complex number into rectangular form, it displays an error. I think I am doing something wrong. Thanks.

Using galaxy tab A, app does not rotate. Option button does nor work

How to convert (0.8045+0.1901i) into polar form which answer is (0.947<0°+0.2376<126.86°) by using power cal.......Thanks

It's ok so far, but I need to figure out how to use each feature. It's not like it comes with an instruction manual. I'm just learning the basic Science, Physics, Quantum Physics Calculations, and Geometric Figures. So any added manuals out there would be greatly appreciated!! Then I'll give it a 5-Star rating. At least the App works.

Oh, that's right there is no manual and the developer doesn't respond to questions. However, it does work.

I upgraded to pro, but I am unable to access any of the pro features as the options button does nothing on my tablet. I emailed the developer weeks ago and have had no reply.

I like the app however it needs some help support. I find it to be just a little frustrating when you know what you wants to see and their isn't the guidelines or tools available to access for resolve. Please add a legend or better key map items within app to allow users an easier flow or experience

Very good job..!! Professionally done and it works and looks like any professional user will expect..!! It's my preferred classic calculator now, for work and/or home... Keep the improvements and new features coming..

Where? Please tell me!

Very powerful, stable and easy to use.

Simple to use

i^4 does not result in 1. Did I use it wrong?

Good app. Would like to see an option to customize the haptic feedback on keypress.

Does.not rotate, cannot setup font. Refund money not available....

Had the free version was perfectly happy with it. Does everything I want, does math the way I expect when I punch numbers in. I paid just because I want to support the app maker not because I needed features in the Pro version. It is that good! Wish I had this exact calculator in physical form.

Ez for use , neat

This is a great calculator. Fantastic graphics.

Useful

$ well spent. Needs a user guide. Update is awsome! (Unit conversion is the next logical enhancement) p.s., I preferred the older icon :)

Like the preferences on function placement . This allows for fast calculations for the most commonly used equations. Everything a calculator should be.
