This is the very best calculator ever. The description of the app by the author does not point out the half the cool stuff. I even persinalized each button!!! Menus are intuitive, easy to use, without unnecessary steps. I just ask to developer to include the switch between binomial and polar complex form in some button instead in the lateral menu. Any case i love the app!!!
I am using this for over a month and this is fantastic. To check the power of this calculator, I entered a hard integral problem. It took a minute and exactly found the answer. One request to the developer is that you should add limit of x,y tending to a,b that means two dimensional limit. It will be extremely helpful. Graph is not the best quality. I entered the general equation of a circle and it showed no graph. Scientific calculator is best. Better than any other app.
It's a really nice and useful app with plenty of functions. I installed it because I wanted to calculate probability distribution. So I would have rated 5 stars if I was not frustrated by th confusing (if I dare not say wrong) results of normal distribution calculation. Test it many times with different cases. All completely different results as standard results. Hopefully Philip can explain the problem. Thanks. Update: just received Philip's quick reply. A really responsible programmer. 5 stars
This is BY FAR the best scientific calculator I have come across. This is the best calculator you can find short of buying a Texas Instruments one for an absurd amount of money. Its free, easy to understand, and reliable. Thank you so much for this, my only regret is that I don't have the money to buy ad free (college student).
Supports 3d graphing of complex functions, with real and imaginary output on separate graphs. Supports integration, differentiation and even partial derivatives! Also supports matrices upto 10x10. Would be nice to have support for sparse matrices, that is, without having to input all the zeros..
[REQUEST] Please keep a option for old theme. Even if it is a paid option I will buy it. Edit: changed back to 5 star Edit 2: Yes I mean a option to change it to the orignal styling. As far as I have tried changing theme doesnt make it as it was earlier. Thank you for your quick response and for developing this app which actually is far better than whatever other apps are offerring
An excellent calculator but it's missing a few features. For example: how can I calculate an indefinite integral? Also, when graphing functions in the 2-D graph, I can't seem to find a way to graph a double or a triple function. Also, I can't graph any functions with conditions to it. EDIT: I understand why you didn't put indefinite integrals, but how about graphing double or triple functions? Also, adding domains to the functions is very important in graphing.
Updates 4 times a day so uninstalled Edit: Yes I based my rating on how often it updates at that moment that I saw it updating again. It's an excellent app actually. I just got (overly) annoyed with constant updates cause i only have data, no wifi most of the time. 5 stars minus 1 for that is what I should've given in hindsight not the other way around.
This app is great! It's very fast and has vast amount of features with new ones being added regularly. It's almost like a calculator from a maths students' dream with all features in one.
Excelent tool! Very intuitive and easy to use. Congrats to the developer! Each time I use it, I am pleasantly surprised by discovering new features. It has almost all functions needed by engineers and scientists in various areas.
Mr. Stephens,wonder if full programmibility planned for future-releases? Also,how can I enter a 500x1 vector or list if need be? ))) Thnx for the promp response.I can certainly understand your emphasis on statistlcs.I wonder if you can incorporate arima time-series into the app possibly using some compact form of modified LM-method to keep app-size managable
Really like this calculator app! It's visual appear looks simple, but it has many additional abilities that regular calculator app doesn't have (operations with complex numbers for example).
I really like this calculator. But it has one grave problem: The integrate function does not work for some functions. Example: x⁻² integrated from 1 to ∞ equals 1 but the calculator prompts diverging values when putting in increasing upper limits and prompts 'undefined' when you put in ∞. This also happens for other integrands with negative exponent. As I deal a lot with such kinds of integrals, this is very unfortunate. Fix this, add some way of saving natural constants and I'll give you 5/5!
Works really well. It has interrupting ads but it's only a small inconvenience for a free app. I'm going to buy the ad free version.
Its good but please avoid video ads. Think about someone having to watch annoying video ads when he is doing his calculations for a long and difficult problem during the exam.
Looks very good, and I say looks because I cannot read the tiny lettering on the keys. I use this app in a phone. Is it designed for a tablet? Edit: I followed your suggestion and it us better. Pending an updated review. Thanks
love this app. long time user. Noticed a tiny issue, if you set ANS to 0 and do ANS/ANS, you get 1. also, would make a big difference if the minimum haptic feedback was shorter, say 5ms. currently even setting it to 1 seems delayed and long.
Excellent . Edit: calculation of limit must be added . I am appreciating your merit in the field of software.---a pedagogic expert in physics .Edit- once again thanking you from the bottom of my heart, wishing a good prospect.23 /03/2020 Edit: gone through your efforts , excellent . Proceed further and you will be rewarded . I am understanding your ability . Thanks from the bottom of my heart .23.4.20: very good and stable improvement you have accomplished . Excellent. Once again thanking you.
i make for u alot of propagandas in my collage, im thankful alot for ur works admin 😍 now i used ur app alot on my math and physics classes and i wish u can make "equation slover" for unknown Variables In undefine (differentiation and integration) for simple example in the differentiation z=y^2+xy^3-5y dz/dy=? dz/dx=? all i want is a smart calculator can slove any undefine equation. i know many calculator had this advantage but they did not help me enough like you did 😊❤💕
The best of the best. Look carefully and thoroughly. It has all the necessary tools for a Maths student. I've used many calculators but this one takes the lead. Kudos to the developer!
This definitely without a doubt one of the best scientific calculator I have downloaded so far. It has pretty much everything required to solve math problems.
The app is really good, it has many options and works as a real scientific calculator. The looks of it could be better and it could be a little easier to use.
Awesome Scientific and Graphical Calculator One Comment - For Double integration the Calculator only allows numbers to be used as limits for y One cannot use the y limits as y=0 and y=x+1 I believe this feature to use y as a function of x as a limit on the integral may be available in a future version Do correct me if I am wrong
will be more convenient if previous calculations can be pasted directly into formula. or just add global copy/paste function. good job.
Nice execution. All features of a calculator are in there. I just wish there was an easy access documentation
I have to say this is the best calculator app. Can you add the various functionalities of 2d graph into 3d graph also. I have to say you guys are working very hard to provide best services to users.
I'm having problem with statistical function like ANOVA, it keep saying undefined. And i think some operation may require tutorials. Edit 1: I tried this ANOVA(list: [7,8,8],[9,7,7],[2,3,5]) in both column and row but i got undefined. Edit 2: Thank you! it worked. But it would have been cooler if you can do it with column/row matrix directly.
The new design looks kinda bad, are you considering an option to change it? maybe put an setting to get on the old design back...
probably the most complete calculator in functionality you can ever find on the market. others can't even handle the "matrix to the power of n" calculation. 👍
I'm using this app from an year, and regret that I didn't find it sooner. The app is simply awesome and I feel like small improvements can be made to do it better. Like solving linear and quadratic equations. Its taking a lot of time to fill both the variables and constants and that could be made better by giving blanks to the constants, it will be easier for calculation...
