This is a good calculator and has an okay graphing environment, but where the calculator shines is the scripting environment, which has a nice programming language behind the scenes. If you need to script something quickly on your phone, this is your best bet. It's got a faster start up time than any other language you might use on your phone with a syntax that is simple enough to learn quickly. Sure, it's not Python or Lisp, but it works for most problems.
Update, 2 years later: It is a major disappointment... that it isn't on iOS... Joking aside, why did it take this long for somebody to create a calculator that feels like it's built for a phone/tablet? Intuitive to the point that it seems second nature from the start. I keep 3 calculators. I have 1 for handwriting and 1 with all algebraic formulas built in, but this is my daily driver. I check iOS for it frequently (Android phone, iPad). Better than the $100+ TI-84 I used in college.
Too many popups, and they disappear faster than I can read them. That makes them useless. If you make them stay longer - this amount of popups will get even more annoying. This is not the right way to educate the user. If you trying to solve UX problems with excessive amount of instructions - you already failed.
I had the app for a while, but I'm mostly still exploring it, since typically when I need to compute something more elaborate I usually have access to my pc, but got to say, so far so good. I definitely appreciate the possibility of making scripts, quite a unique feature among android calculator apps.
Very powerful calculator, reminds me of MATLAB or R, just starting to use it, so will update my review later. Minor detail, would like to have all buttons with dark theme, I can't see well the lower part i.e white and yellow buttons. Using the Pro version.
great math app, with one small bug on my device that hurts me inside like a not so gental cellmate. besides being a great calculator, it has a pretty nice scripting environment. It even allows you to run a script at startup, which lets you do anything from having some variables on hand to defining nearly any function that you can write. Unfortunately, I cant save the scripts on my device. I allowed it access to the file sustem but it still fails to write. Still my favorite calculator though.
Ads no ads, if the app has notifications switching off feature it should respect it. That also means it has all the time connection to push notifications server open, what for? The app itself is brillant. If I want a function or a tutorial I will get it myself. Thank you.
Amazing, just amazing. This is literally the ultimate calculator on the play store. I really like the UI. Everything is well organized. Works, looks and feel extremely professional and definitely recommend it. Good job 👌
This app is great if you need more than basic calculator. It can do algebra and graphics and scripts. I see some comments about having to use * instead of X but this is because variables are allowed so X can be a number whereas * cannot. If you want more than the calculator already installed on your device, this is a good alternative as it can be as complex or as simple as you like
The app is great but would love it if you included built in numerical method scripts because those are practical applications people would want to do especially with the convenience of the phone. I would want to see Bisection method for example. But the app is still great.
This is what I've been looking for! This is not a typical calculator interface (which is limiting), this is using the computing power of your phone / tablet in a much more intelligent and powerful way. Mr. Gromada has created a true gem here! Thank you very much, sir!

It has the most detailed funtions and qualities I have ever seen. Can't wait to see what it will bring in future. I really liked the graph representation and its really satisfying.
Great app for math savy person. Very powerful. Great to be able to carry results. The interphase could be more friendly. Being able to use labels will be giid addition.
Really well made programmable calculator. I inquired earlier about an issue with Android 10, and the developer not only responded quickly, but soon after pushed an update. Awesome work. It's now definitely worth 5 stars.
Seems not to include complex numbers. Underscore might be frequently used but is difficult to type; adding another row for symbols or long-pressing "space" to type it would be reasonable.
This app exactly what i want for a long time. This will be perfect if it had option to disable vibrating and make wide keyboard in landscape mode for both hands.
I am only scratching the surface of the power of this program. I am hooked. Intuitive interface let's you unravel the many features at your own pace.
This application is useless. Every time I try and calculate anything there are so many pop-up messages that I cannot input anything. I already know how to use a calculator. I don't need a pop-up telling me how to use every feature and option.
It's has a bit too many functions I think. I will have to take time to learn about it. Overall, a good app. But maybe you should include a simple calculator mode. Just my suggestion
Good app but bought by mistake (I didn't see the Google play license check at first). this DRM is not a Google requirement. As long as this "permission" is set, I will not buy the app. Sorry........... edit 17th November 2021: As I took the opportunity to get the app for free, I cannot complain...thx a lot
Ok, good. But how can I open the menu after turn off show menu open button option. Update:Thanks for your reply. I really like this calculator after using it for a while. Keep developing this app..
This app is very well constructed. Superbly functional. Obvious purchase. Although it might take a little time to understand how IT thinks, you'll probably end up quite pleased. Strongly recommended.
I really love this calculator, that really isn't a sufficent name as it's more a specialized computer. I haven't even begun to scratch the surface but I'm immediatly reminded of my beloved HP48g (w\o RPN) of school days. Keep up the great work!
This has so much functionality in it. I doubt very many people will find it lacking. It's pretty it's smart, it's functional. Would definitely recommend.
Very sophisticated calculator. Has everything I need and it's the only one I have installed. One thing I would like to see is the ability to change the font size.
This is an Awesome mathematics app. Great design, excellent job. Hip hip hip Hurray! Still the most wonderful math engine you can ever have. I love this great Mathematical machine. Indispensable great engine. You all at Scalar have our great support. PAA.
Wow, inagine an app that actually lives up to the description. Rare but in thus case a reality. I'm learning new things about each time I use it. Great
Incredible app! Super powerful, I haven't even begun to use all of its features! Definitely worth your time and money, if you need an app like this.
I just hate when people write false opinions of an otherwise very good software. Scalar Pro is almost perfect. Thanks buddy
One of the best app I paid for. It does what it is supposed to. Five star. Only two concern: the graph is a bit complex to deal 2ith. I use Microsoft math for that. And second one thought the scalar script is able to handle small scripts, it couldn't utilise the powerful phone RAM/Compute to deal with a lengthy one. I didn't even bother about the free one.
