  • Go To Calculator

    by Jigger's Tattoo

    Best calculator for an iPad. Simple and intuitive to use, but has relatively sophisticated functions. Would be nice to have a % button. Other apps may be cuter or way more complicated, but this is the one that always gets used.

  • Easy, simple to use

    by MsGeriLynne

    Like the calculator. Really like the line itemization so as to verify you totals. Would recommend.

  • Really like it.

    by Purple Wind

    This calculator has very good functionality. I especially like the computation "storage". I use this calculator 90% of the time I need to do calculations. For everyday home use, it can't be beat.

  • Great product

    Very pleased with it. I would hope you would add a % button to help make these types of calculations quicker.

  • Love it

    by Mofus400

    Easy to use, very helpful.

  • Why


    I like this app for the basics, but i would like to easily press one button for SIN to the -1.

  • Why even deploy this app...

    by Jbigby0619873400

    My cat would have done a better job in calculating numbers; I don't even have a cat - did Sarah Palin's baby create this app?

  • Calculator

    by Langsdorf

    This calculator has a strip at the bottom that displays advertising. This is very annoying and should not be apart of a calculator that you already pay money for. They did not tell me that this distracting advertising was a part of the application or I would not have purchased it. My advice, purchase a different calculator application.

  • Calculator

  • Calculator Review

    by PwdAH

    Nice basic calculator, we'll laid out and easy to use. Still, I would find a loan function far more useful than the standard scientific functions that come with these apps.

  • Smart and easy

    by PC 3498

    This app is smart and easy to use...I took the others off my iPad and only use this now.

  • Beware

    by LadyLitespeed

    In the app you will be invited to upgrade to the full version. In the app description, it says the app is on sale for 99 cents. I purchased it and was charged $1.99 (which is what was shown on the purchase button). The calculator is fine, but don't be misled about the price.

  • Nice easy calculator to use

    by Zebbidog

    Has most common function and makes for a nice calculator on the iPad.

  • Calculator usurps audio

    by laminatedhalo

    Opening this calculator pauses music since it takes control of the audio stream. Also, the screen shots are misleading since they only show the app after an in-store upgrade has been purchased. Developer honesty fail.

  • Good

    by Savannah. 3465729790853267

    It works very good

  • Great so far

  • Nothing Fancy but Exactly What I Need

    by Eri5437

    The best thing about this calculator app is when I hold my iPad landscape, right side become a record of my past calculations. This great when you happen to forget or lose track of your calculations.

  • Love It,

    by KC.tac

    Best calculator I have found!

  • Alexa

    by Hhhfig

  • Love it!

    by Boodapug

    Does what it's supposed to do and no annoying pop up messages every time I open it (like the last calculator app I had). I like the calculation history and that it shows what I have entered for each calculation so I can double check my input.

  • Calculator

    by S. A. 1946

    Has all basics. Like tape memory.

  • Highly Recommend

    by Marigold953

    I have used multiple calculator apps on both my iPad & iPhone. This by far is the best!!! I love how it gives you the notepad next to it so you can keep track of where you are should you get interrupted. I would highly recommend this app!!!

  • Great App!

    by funkybluegrass

    As a pilot I use calculators every day for multiple purposes (logbook, calculating performance data, etc). This calculator is simple and just works. Smooth, simple, love it.

  • Great app

    by dat04

    Was looking for a basic calculator app. This one works great.

  • Great App

    by Janai malone

    Great for school work. The ads aren't distracting!!

  • Best Simple & Effective Calc App

    by LithiumMethoxide

    When I got my iPad Mini Retina, I was pretty surprised to see a calculator doesn't come preinstalled. After checking out a few of the options on the App Store this one looked simple without any other extra gimmicks to be bothered about. There is an ad at the bottom of the screen, but it's not overly distracting. The apps history feature is very handy for doing multiple equations without having to copy & paste or write down previous answers. For a simple and easy calculator app, you really can't go wrong with this.

  • Calculates as expected

    by Folsom Fallies

    It is easy to use and operates as expected

  • Not Full Version

    by technojerry

    You can't even try the scientific function part of the calculator without doing an in app buy for the full version. The description doesn't even tell you that. It also hasn't been updated since Jan 2012.

  • Great

    by TUU@12

    Great app.

  • Drool

    by DGCooley

    Great app

    The history calculations 'tape' window makes it a great tool for my office and at home.

  • reviewer

    by !@#$1234

    REALLY GREAT. I've tried several for the iPad and this is by far the best one. Works very well. I do wish I could lock the screen when I turn the device so the calculator wouldn't switch to a scientific calculator. Functions Great! Love it. Highly recommend. Renata

  • Very good calculator

    by hliu98

    It is one of the best calculator after test more than ten other calculator app.

  • Great app

    by TheFoxyLady54

    Quick, easy to use. The only calculator I have on my iPad.

  • Wrong calculation.

    by JpWhite22

    I am deleting it. It told me several times that 45 x .75 = 78.75. There was absolutely no 1 in front of the .75 and I have several screenshots of the program's blatant error. Scary if you are using the calculator for something important. I am just linking to google's calculator as a link on my main screen. See ya...

  • Great job yo
