Latest reviews

(2021-03-06) DoubleU: this is a great calculator, but can it solve for variables? every time i put in a variable it just says "error undefined"
(2019-09-05) Max Feige: Very useful little application for the homework I have that saves time and valuable desk space in lectures. For a free application this is about as good as you can get! Supports a lot of advanced mathematics as well, giving a lot of control over what I need to do.
(2016-09-11) S Hawke: Nice app but doesn't handle numbers very well on a samsung exynos chromebook. I haven't yet tried it under windows and intel environments. I would expect the processing to occur using more precision or currency accounting numeric types under the hood to avoid leaking precision. eg. 69.3 − 10.5 − 2.1 gives 56.699999999999996 rather than 56.70. Please fix it!
(2016-08-17) Absolutely amazing.
(2016-07-15) Marc Mull: need practice
(2016-05-25) Matthias Arndt: Option to interpret , as decimal point (German keyboard) is missing, leading to unnecessary input errors.
(2016-04-02) Greg Nixon: Works as quickly and as easily as a regular calculator. Like it very much.
(2015-12-05) Glenn Minks: Intermittently will not perform a simple mortage payment calculation. Returns a calculated value of 0. It's like it's missing the "1 -" and dividing the product of principle x monthly interest rate by a number very close to zero and then rounding to zero. Sometimes it works, sometimes it doesn't... odd... I'll stick with my old calculator
(2015-11-21) Ben Hope: I love this for doing my physics and circuits homework. It makes calculations with data and formulas lovely. My only complaint is the multiplication syntax isn't as flexible as that of my TI-84, but I can't type with a keyboard on that device, so this still wins out.
(2015-10-07) Timothy Doughty: Unable to do modulus, which is what I needed. Other than that, pretty decent.
(2015-09-29) Neil Wyman: no nth root. I need a $5 scientific calculator
(2015-08-27) zdenek cada: it is what i need!!! good work, guys!
(2015-06-30) John Bladon: Does not do division; rather it converts a rational fraction to a simple fraction -- Useless
(2015-04-29) mhmood hassan: nice but need more fuction
(2015-03-03) Rick: well at least its helping more than just paper and pencil
(2015-02-26) Zachary Keeney: Thanks. Keep up with it!
(2015-02-20) Zoltán Erdőkövy: The reasons I'm using this extension: Implied multiplication, custom functions and variables, results as either decimals or exact fractions, keypad for mouse operation.
(2015-02-16) Cibean Cristian: Waste of time.
(2015-02-09) Leon Niceday: Very good. However, a bit slow, and wish it pop-up as a simpler calculator, thus faster, then, if needed, I would click on some 'advanced' button and bring the full power on.
(2015-01-22) Josh: better than the default calculator on my chromebook
(2014-08-29) Happy CG: TERRIBLE APP. I immediately had to delete it due to how poorly it works. It constantly has errors for even simple calculations. I would give it 0 stars if I could.
(2014-08-26) Lilia Romero: is very well
(2014-08-24) Alain Hoffmann: very useful and gives exact result ( like sqrt(2) - 1 )
(2014-06-15) Christos Gkantidis: Really great app!!! Just what I wanted. I use it all the time for Physics and Math.
(2014-05-31) Gfast Gao: I love calculator like this one that can really help me make thing done! GOOD WORK!
(2014-05-29) Stefan Barney: Free scientific calculator; no problems found yet.
(2014-05-12) Mostafiz Rahman: Loved it!!
(2014-05-04) Tom Jones: Wow! This is the online calculator that every Engineer / Scientist can use daily! It even has an Engineering format to display numbers. Being able to program it and store scripts and variables allows one to extend it beyond the authors design and thus allows one to add 'Constants' do conversions and a whole lot more! One should not complain as the calculator is free! Try writing a better one. Thanks to silentmatt for this gem!
(2014-04-25) Dr. Dharmraj Ghodke: not good for scientific use at all
(2014-04-05) very helpful app!
(2014-04-01) camma andstar: Good job at making a simple PYTHON/SCRIPT CALCULATOR THAT ANYONE WITH COMPUTER EXPERIENCE COULD MAKE!
(2014-03-23) Stephanie Carty: Should be able to use parentheses to multiply. If I type "-4(6)(-4)", it outputs " -4 6 -4 not a function". Should output "96". Frustrating to have to use *.
(2014-03-23) 白霜: Although it is English, it still helps me really! I hope there will be Chinese(Traditional) version.
(2014-03-12) Joachim Löw: Well done! Especially the option to write scripts is great. Some more script examples in the help would be helpful to get used to the syntax.
(2014-03-10) حمزة محمد التمسماني: very good
(2014-02-20) Shrief Mohamed: it need more decent library of equations and it will be perfect
(2014-02-15) Asad Rehan: Best
(2014-02-03) Shankar Sesma: good, need some improvement
(2014-01-27) Jasmin Escoto: okay lang.... simple calculator...
(2014-01-18) Douglas S Dierdorf: I like it, a programmable without RPN
(2013-12-30) Peter Milewski: A clever calculator with lots of options. For simpletons like me you can do multiple calculations then take screenshots as a record of what you have done, that can be checked later for errors. For the sophisticated there's plenty to satisfy them too.
(2013-12-19) Tony Metger: Best calculator for the computer, I use it evveryday and it's great. It displays calculations very nicely and the possibility of adding constants in a script is very useful. Thanks to the developer for making my life easier!
(2013-12-15) Stasia Taylor: horrid if you are doing chemical equations
(2013-12-09) Jenny Chulee: This is really good. Helps me with my reading log :D.
(2013-11-29) It is amazing at all the functions I ever wanted. Has some problems with imaginary numbers. Should have an instructions manual to script writing.
(2013-11-25) Courtney Williams: It just doesn't do as good as what a real calculator does.It keeps giving me fracations
(2013-11-22) Leonardo Prosperi: It cannot calculate what is in its icon: e^πi= −1.+1.2246063538223773×10−16i
(2013-11-16) Kason: Has all the essentials that a scientist wants in a calculator. You can store variables. Perfect.
(2013-11-06) Works; too bad it doesn't do graphing as well. Suggestion to the developer based on feedback: try auto-rounding the digits to n places (n is determined by a default and/or user) so people don't get confused with the computer's imprecision. Suggestion to reviewers who have this problem: it's a known phenomenon in computer science that computers can give slightly off answers for floating-point calculations. Just chop off the extra "stuff" at the end as you feel fit.
(2013-11-04) David Jeng: One of the best online programmable calculator
