handyCalc Calculator

It's small. It does maths just like you learned in college. It draws graphs. It even does conversions. The way it opens a new work-page so often is odd, and closing them isn't intuitive. However these don't even warrant dropping a star.

awesome SMART CALCULATOR.

[3]IT HAS BUILT IN UNIT CONVERTER. [4]IT HAS BUILT IN FORMULA AND WE CAN ADD ANY FORMULA. [5]IT SUPPORT FOR SAVE DOCUMENTS.

Love the app, but the currency converter will not update anymore. This has been for a couple of weeks now. Update 30 Nov 2017: Having uninstalled/reinstalled the app, the currency update still refuses to work.

Finally a calculator that has both decimals, fractions,and basic calculations. It took me 20 min just to find it thanks alot.It should have gotten 5 stars altogether with no bad reviews.

This calculator is, by far, the easiest to use, and is the most effective at doing work that a graphing calculator can. I actually prefer this app over using an actual calculator, as it's easy to understand, edit mistakes, and the interface is fantastic (the formatting of equations looks just like it would if handwritten)

Best calculator I've found thus far. I really like how you can write out the calculation and touch a place in the equation to make changes. It's simple and not filled with flashy useless stuff, but you also find yourself surprised to learn it still has a lot of function which is cleverly built in.

Works well, the only thing I would like it's the ability to remove a 'page' but that's small beer. It has currency and unit conversion, does scientific calcs, works really well. No ads either. Refreshing.

I frequently use this for engineering calculations - much better than anything else I've found.Been using it for years Pros: - Excellent natural display - Very lightweight app (no permissions needed) - Wide range of functions - Free

Best calculator there is. Missed it so hard on iOS, now I'm back on Android and this is among the first apps I download

6 years usage, and still my preference. Currencies, units, complex calculations, fractions, formulae, separate work spaces. Wish I had it on my PC. FroYo Desire to Marshmallow One m9 and multiple phones in between: consistently a go-to app. Thank you Dev. Hope karma pays you some favours.

Been abandoned by developer and certain functions no longer work, most notably the Currency converter. Emailed Dev but no response

This calculator is simply the best I've ever used. The amount of features are just staggering, and it works so much better for long calculations than 90% of other calculators out there. My only gripe is that the UI looks like it crawled out from late 2007. A bit of material goodness would likely make this app soar in popularity, as people tend to judge apps by their icon, and frankly this one looks unimpressive. If the dev is still around, I implore you to update this apps' UI and make this app fantastic.

It is one of the best calculator but it has one drawback. In one document once the page is created you can't delete it. Since I work on one equation over a period of time, it becomes clumsy due to large number of pages and non availability of delete page function. It is must. UI can be improved. For tab option should be given to work in portrait or landscape mode not only lanscape mode.

Favorite versatile calculator app. For some reason, I can't save unit converter shortcuts to home screen anymore got this app. They disappear after restart. I use unit converter frequently for work. Please fix!

Holy cow, this calculator can do... everything. Best calculator in existence. Seriously. I'd rename it to Brainiac then it could even fight superman. Really wish they would revamp UI or allow me to :)

Still the best by far. Interface has some minor flaws. Too bad it doesn't seem to be updated anymore.

seems to have overflow problems. e.g. do 20^20 (that's 20, shift, X^y, 20, =) and note the answer. Now do 20^15. Look familiar?

Please add and absolute function for graphing. If there aldready is one I am sorry I couldnt find it. DEVS TRY TO MULTI SCREEN SUPPORT FOR NOTE 2. 5 star app though very very good Plea

Nothing, absolutely nothing, like this on the Play store or iOS App store. Spartan but clean functional UI, which I personally don't mind. Great Currency and Unit Converter, of which I'm a fan. Have used countless calculators, but I wouldn't ever leave this one. Devlpr, Thank you.

Unique app in the whole Android universe that indicates insufficient storage space in my mobile device. Ridiculous.

Thank you very much for a simple, yet powerful tool. If I may ask; (1) it would be great if the calculator has option to delete and insert page at any section of an opened document. (2) Populate the free topmost section, where the icon is, with quick access buttons hidden away in menu.

Great calculator, though you might not guess it by the doofy icon. The icon and UI could be a lot prettier, but functionality is great. The parenthesis and division signs make big formulas way easier to read than on other calc apps.

Have used this since having an HTC Thunderbolt. Does a lot more than I usually need. Has always covered more complex calculations.

The best calc ever. I'm telling you get this now. Before your life suffers.

Not the best possible one but none seems better than this. The only thing better than this are the full fledged computational tools like maxima or octave. Still i wish copy paste utilities cud hv been better implemented. Even editor interface doesn't work very well. I hv also seen this crashing many times. But the biggest drawback is lack of import/export documents.

This gets installed in the first batch of apps on all of my devices. Lightweight and straightforward, plenty of features like unit conversion. Best feature, and for me essential, is the displayed calculation history like you get on a graphing calculator. Great app.

Not terribly easy to use, but play with it for a little while. Once you get the hang of it, there's all sorts of engineering calculations that become a snap with this app. Kind of like a mini wolfram or Matlab!

However after last update it will no longer rotate screen for when I'm putting in long calculations

Simple calculations are simple, but it can do just about anything. Handles fractions beautifully. Keeps a full record of calculations, which is surprisingly useful.

Performs almost every function you could ask for without requiring permissions or payment. Got me through college.

Awesome on high-res portrait displays, not so much on anything else. No keypad options, and with the current setup in landscape all of the number keys are off screen, making the app completely useless. Even with my FHD phone it won't rotate to landscape when mounted for GPS use. Seriously needs to support landscape mode and small screens.

I have seen so many good calculators at google play store, but this one is the top of tops. God bless you for making it free with no in-app purchases. You give it all to us. Thank you!

I will give five star when you adopt the material design.

I love it because of the very simple type of calculator and easy to use.

The Best calculator with all the features you can imagine, I don't get it why isn't this a editor's choice app!!

I tested alot of calculators if not all in the play store. and this is the best calculator period. its been with me for 10 months and I use it daily, never failed me. I now even use it instead of my real casio calculator. good work devs, keep it up.

After so many years this is still the best calculator I have ever used, and unbelievably still the only one with natural mathematic display. But it really need a new icon and new design. If you can't do it then give an option for the community to design themes for it. Please don't abandon it!
