Graph plot section sometime lags on even high endings devices... I suggest your team to fix this bug...one more question is that how to plot more than one graph Simultaneously???

Performance issue? Then calculating something like (1+1/[big number])^[big number] I get 1.000something instead of ~e. Or it shows result of previous calculation. (Phone LG E975, cyanogen 12). Flash news : "cos(pi/2)=.999E-18"...

I would really like to be able to use units in my calculations For example, I'd like to be able to set the metric unit system as the default (or some arbitrary set of units that I choose), but enter "2in + 5" and get 30.8mm as the result (i.e. 2in*25.4mm/1in + 5mm). This is how my TI-89 worked that I used throughout high school and college, and it was awesome.

So many features, and free for all! If you're a math or a science major, this is perfect! While simplistic, the drag select method enables the user to use all the features on the same screen. Furthermore, it provides numerous and customizable functions and constants and graphing features. Too good to be free!

Thanks for this app 🙏 Got confused at first! I'm a chemical engineering student and this is very helpful and beautiful design. But please add a separator between buttons Also add more math calculations, like matrix, complex equation solving and so.

Great calculator app but... it needs instructions on how to do simple steps! I still haven't figured out how to do fractions, and I know it can from the description. Took me a while to figure out how to do negative numbers, etc. (minus sign before a number)

User reviews

Best calculator ever A very useful and very good done calculator. I use it every time I need some quick and hard calculations. Just a single suggestion, you need to add a way to add exponential on variable and constant panel where you add a new constant. The only way is to edit the current result of your calculation (ans).

One of my go-to calculator apps I like the configurable options and layouts. However it's difficult to get used to the equals sign in the top left or wherever it is depending on the mode. Perhaps let us move the copy/paste bar to the left side, and equals can be on the right side, configurable tiles? I wish there was a RPN mode. Graphing is a plus. 3D mode is cool, wish I had this in school. I use the floating window extensively. Wish it had option for % transparency.

Awesome calculator! I love all the unique features of this calculator. The quick access to engineering functions, ability to create my own variables, window mode, angle and base conversions... I could go on, but I am ever so slightly disappointed that there wasn't an option for Dozenal. It's the only thing I have a second calculator for.

Best calculator but needs true scientific notation and sci. notation button Hello! Thank you for creating this wonderful app! It truly does outshine every other calculator app I have used by far. However, it would be way better if there was a menu option to switch between engineering notation - the current "scientific notation," ex. 39.032E0 - and "true" scientific notation, ex. 3.9032E1. This is a very minor issue, as it's easy to shift the decimal and add to the exponent in your head, but it'd still be nice. Far more importantly, I think it should have a scientific notation butt

Calculater and function plotter in one Great calculator, capable of solving derivations and simple integrals. The function plotter is quite useful to me as physics student, especially as it's able to plot 2d functions. My only critic is the hard to read output; depending on your input, some simple things like (-1) will be diplayed as (ln (1/e)), or powers being displayed with " ^ " .

Amazing smooth and intuitive And I don't see any ads... Suggestion: Matrix calculator which supports value inserts with space separator... With that you will kill all other apps entirely... No idea why this isn't the number 1 as I use it instead of my real scientific calculator because it's more comfy

Very powerful tool This tiny calculator app is more powerful than those big hardware calculators we were using in engineering studies. Very good work, keep it up! One thing I discovered is when I punch in e.g. sin(180) in DEG mode, it will give me a small number, but not Zero. Is that an internal rounding error?

Great simple calculator After getting my LG G4 which oddly didnt come with a calculator I researched some calculators and this was rated one of the best and I can't agree more. Its great. The design looks good to what I'm used to, the speed is up to par and the features it has I find unique like windowed calculator so you can multitask with it.

Best Calculator App It is easy to use. It adjusted nicely based on orientation. The button slide feature is nice. Also has a nice look.

Great calculator but... Its a great calculator bt the only thing i don't like is its interface...Its interface is very hard for the first time user like me...Plz make its interface easy......And also add some more mathematical calculation and plz add a option to show ans also in numerator and denominator form not only in decimal form it will be very helpful for students

Best calculator so far! I tried a ton of calculators and this one is definitely the best, and that's saying something! I live how with amidst as little buttons as a basic calc you deliver about as much features as midst scientific calks +some exclusive (i think). Or can be used just add a normal, basic calc, or as a scientific one without tweaking. The astetics are good The gestures for the scientific functions are just great. I highly recommend using it unless there is a function you can't get by without and this app lacks it.

Love it! Been using it for ages, best calculator I've ever had. Just one problem... Every time I launch the app I get this same error: Some user data could not be loaded. Please contact developers. Unable to load: AFunction{name='crd_r2p', parameterNames=[r, u, n], content='-eq(n, 1)*(-atan(u/r))-eq(n, 3)*(180-atan(u/r))-eq(n, 2)*(360-atan(u/r))+eq(n, 0)*(py(r, u))-eq(n, 4)*(-(180+atan(u/r)))'} And the function gets removed. I really need it and have had to recreate it from the error message 3 times. Any ideas?

Best android calculator This is simple enough to use for day to day calculations, but powerful enough for pretty much anything you'd want to do. Equation entry and plotting are actually just about as simple as working out a tip. I can't think how I'd improve it, particularly once you've used an app to hook it into the swipe-up gesture and make it always available
