Best ad-free expression-based calc After trying many calcs out there, I have concluded this is the best ad-free expression-based calculator available. It doesn't try to look like a Casio calculator, and it lacks graphing, conversions, and advanced features. But I, again, it's ad-free and expression-based--that's what does it for me.

Martin Jennings

Decent calculator no fuss. I think this calculator is clear and easy to use and I am glad the user interface is kept easy to use. I notice a few improvements having used this application in previous versions.

Where's the cube root? To get the cube root, you have to do a square of 1/3. Cumbersome... if you can increase the standard number of functions and also go with vertical scrolling on long equations, rather than horizontal, would be a very accomplished app...

User reviews

Best Calc, No Permissions Requested Excellent calc app, easy to use. Thank you for not requesting any permission :-) Galaxy Nexus, Android 4.2.1

Best calculator Latest update now has a button/icon to clear the entire screen of calculator. This can also be done via long press on the screen, you can also opt to clear one line.

Previous version worked fine on HTC Hero 1.5, this one FC's instantly, and I didn't save the app. Oh well, time to upgrade the OS.

Great Calculator I use three calculators. This and handycalc (and graphcalc on the pc). This one is simple, shows a list of previous calculations. Handycalc is good for complex stuff

Perfect I've been using it for over a year too. It's UI is just perfect, and has all the functionality I could ever need. Best Sci Calc I've seen yet as well.

Best ever. What I love most is the history displayed. You can delete individual entries or tap on them and modify to create a new entry. Awesome

The best calc I've found. A smoother interface, smarter operators--self closing () etc, and conversions would be very welcome.

My favorite Android calculator, though I would request an option to view answers as a fraction.

No instructions or manual. Eg how do you do vectors or matrices. Bitwise doesn't work.

Good calculator You can view all the steps of the calculation. Helpful while making calculations of long list of items like groceries.

Decent application, and I very much appreciate the effort. Unfortunately, Eval is definitely the better calculator.

I carry a TI 89 Titanium but I find myself using this 1 more than the TI 89 because this is back lit and I can see it where I can't TI89.

I love the UI but it doesnt matter because it does not look full screen on my Galaxy Tab

Been using this more then a year! Still the best! Just noticed the nice touch on your icon! XD

Need to have graphic, solver. Will be best app for Droid. SGS

Amazing! Nothing else like it out there. Has most useful functions, copy and paste, store, good button layout. I use it as a replacement for ti 83

Clean UI design, supports high-precision calculation. 5 stars (until I find something not good enough... *^_^*).

Only complaint is since app drawer is alphabetical m for mathdroid comes after c for calculator lol

Try handy calculator saves history and has graphing ability

Very beautiful and useful app. It would be even better if there's an option to shift between very simple and advanced mode. Or simply swipe to shift.

Great! Closest thing to a TI-8x calc i can find for my phone. Droid 2; Android 2:2

Best droid calculator I've found by far. Multi-line is great and using previous answers is a good addition

It would be nice if each result in the history could be accessed like: 5+(press history item 2). Currently just overwrites existing input

Graphics and polynomial solver would be cool too, now using 2 more apps for those functions

Latest update has broken keyboard input with the ShapeWriter keyboard. Doesn't allow entry of variables any more. Please fix :)

one of the better calculator apps I've installed on my phone. Thank you for the haptic feedback, though it feels a bit weak.

Great UI and like being able to see all actions. Would like 1) Bigger number pad (G1) and 2) Ans key should be auto inserted if a function key is 1st.

its a great app. its actually worth money unlike many other garbage apps in the market. need some fix such as no negative sign. multi line is the best

If only it allowed for degree/rad selection for trig functions it would be perfect.
