Natural Scientific Calculator

I teach science and math to kids in high school and middle. The way this calculator is setup, with boxes in the display to show where the numbers go, and the automatic brackets, well, it's just brilliant. I have suggested this app to my students, and they really seem to like it a lot. You can't get much easier than a Calc that writes out the equation for you and tells where to type the numbers. I love it!

Very unique and useful calculator with a beautiful UI and functions I've not seen in a calculator app before (fractions). I liked it so much I paid for the in-app upgrade to remove ads and give me themes. The only problem is that once I set a theme that setting disappears and goes back to the default theme when I close the app and come back in later. The developer is aware of this issue but has done nothing to correct it. Considering this is a feature I paid $ for I'm not real happy about that so lowering rating.

I love this app. A suggestion: One thing all apps of this type lack is the sum function (big sigma). Casio's products have had it available long ago, and it's the only reason why I (and my students) need to buy it instead of just using this app. If the sum function is included, we will fully support this app forever.

Let's start with the good, your design and functionality, this was the reason I bought your app(I already purchased the premium version of this app). It's got a great design and it truly makes me look at my old calculator like it's an[ insert insult here]. Functionality wise I really enjoyed the long press for the second function instead of having to press a second function button. The bad is that it isn't complete. It doesn't have an modulus function, and it doesn't have an open base log function, etc. .

Great calculator app, room for improvement would be being able to change theme without it reversing back to its default theme. Every time I've changed the theme the app has always changed itself back to its default theme when I go to use it later, could you please fix this issue.

Has all the functions that I need for my pre-calc class and very un-invasive ads. Especially like how radicals and fractions (including mixed) can be entered without alot of parentheses.

Tried different calculators on Play Store. None of them has flexible number input for exact position, i.e if you want to change value of root number after typing all the equation, good luck deleting everything to get back to the root. This app could change any value in any position.

I am very much used to casio Fx ES series calculator so i was having trouble using other calculator app. But this app simply gave me what i needed. 5strar!

First I would like to congratulate the makers for such an awesome calculator app, lately I have replaced my fx-991es but then one of the things I found missing was a linear as well as quadratic equation solver with variables. Try to include it please. People will be willing to pay for a complete calculator. I don't want to carry one with a phone already in my pocket. Cheers!

Why do I have to delete previous calculations first or erase them by tapping AC before doing new calculations. Like all the other calculators in the world after tapping on anwer no one should have to delte the previous inputs before giving new imports.

I just love this app... . No words..... I can't explain how dependent I am on this app as a 12th std student.... I just need this for all the crazy long calculations..... N with this I can do it in first step...... The only app which can edit the steps in between with ease..... Thank you!!!!

I have commented about it in the past and I said I am surprised it is free considering how much one can do with the app. I wish I knew how from this part of the world, to throw a coin to you guys in appreciation of your effort. Is it possible to include degrees in trigonometry in a future update. You only radians.

Although it has a nice User experience those visual effects are pretty annoying. Especially those ones for AC C. It would be nice if those can be disabled for the sake of performance.

Layout is beautiful. Displays your input the way you'd write it on paper. Simply the best calculator out there. I don't know why all the others aren't just like this!! A must if you're in science.

you have to remove ad first, in previous versions there is no such kind. of ad comes, but now i update and ad is coming, this is very irritated, i suggest u in free version dont give us any features but u have to remove ad first. i hope u understand. ASAP

it is impossible to use it if you are working with degrees-minutes-seconds (for example arccos(cos(20°36'18")+sin(15°25'18")).

I changed my device recently and I am not able to restore the purchase of the premium or pro version. The ads keep showing up.

This app is a real life saver! I was in class where we had to use buttons on a scientific calculator that no one in my class had. With them having their phones so they had the basic calculator. But I quickly found this app and was able to do the work quickly and efficiently thank alot. If not for the app I would be behind on the material.

Easy to use, has all the necessary functions. The ads is a bit annoying but they gotta make money somehow

Just make one more dream true. Add the ability for answers to show up with square root and special symbols (pi and engineering ratios like kilo, mega etc)...

I've gone through all the top rated calculator apps and this one is easily the best. Where most other calculators attempt to mimic a physical calculator this one takes advantage of being on a smart phone to give you some proper formula editing capabilities.

I was struck with log problems and to tally my answer with complex question there was nothing. Finally I found this app,this app is very easy to use, and must download app for science students !

Fast, intuitive everything is great. Only thing, calculations of fractions sets this one apart, yet there is less room to fully express the expressions. Please increase room on display and lessen it from keys. Thank you

Small problem with putting into memory from input line, will only do it with answer. Really nice interface, would be 5*

Best calculator app I've ever used, most phone calculators I've used can't stand up to a Casio calculator. However this does a pretty good job

I was multiplying only positive numbers and the result was a negative number :(

Most awaited app for a long time. But I couldn't see the "Pol" and "Rec" functions which I always have to use.

Excellent calculator app, works very smoothly and does everything I need it to do for both chemistry and physics classes without issue. Very intuitive display, history, scientific notation button, themes, everything I could ask for. Works fine as the free version but the lack of a bar ad across the top makes the interface a lot cleaner. I'll be using this a lot over the next few semesters of college.

This scientific calculator is the next level. The other calculator apps are just as good as this one. One search for a calculator app gives u many high rated apps. However this calculator app is highly customisable and extremely nice to use. It really has that smartphone appeal. With its amazing and beautiful UI and easy access to secondary functions this app is definitely worth getting premium!!!

The calculator might look pretty, but one after another ad in flashing font lying about viruses, memory, malware, and every kind of malady that it tries to make you believe has infected your phone just turns what might otherwise be a really nice ap many users ..would.. pay for, into another ..thing.. you can't trust. Two stars is probably one too many. (uninstall)

Good, but there are a couple of things that would make it better: . Arrows to move around . A movable cursor line e(like normal keyboards in other apps) . Increase the size of the screen and reduce the number pad (maybe half and half)

I just downloaded it I don't know if the display will be short-lived as most calculators are and then you have to pay for the pro version to keep the display as the way it was when you first installed but it is well done to say none the less

This is one of, if not the best, calculator app available on the play store. It's a really good calculator app.

I miss a lot the horizontal mode and statistic functons like standard deviation

Awesome! It would be the best if it had a Matrix, equation solving(2/3 unknown/quadratic), calculus, 2D graph plotting, few storing memories, few built in frequently used constant values & navigation keys to move cursor!

I use the fraction, radical and parenthesis functions all the time and I would really appreciate it if there were arrow keys to move the cursor around rather than trying to pinpoint the location with my finger. Otherwise its a great app!

Great design, easy on the eyes and very useful. However, this app really needs degrees, minutes, seconds (DMS)

Beautiful calculator, intuitive input interface. Way easier to use than the scientific calculator I previously carried to class. I love this calculator enough that I paid for premium to remove the added ads and to support the devs. I hope the calculator continues to be worthwhile to develop. Thanks!

Impossible to use secondary functions. Trying to press the secondary function only registers the primary function of the button, I even tried with a stylus.

oh thanks god.. i don't need to buy a Casio calculator now..i will download this app aNd i can used it.... anytime...
