Calculator‘ App Comments & Reviews

Calculator‘ Positive Reviews

The History Function is Simply FantasticYour Calculator app is 100% the absolute best calculator app I have ever used. I have diagnosed ADHD, and trying to keep a budget can be difficult (I have literal notebooks filled with budgets from years of trying - lol). The history function & feature on your app has allowed me to go back when I forget whether I included a bill amount, and verify whether I need to recalculate. It has saved me so much time & money in my many years of using it. Your Calculator app was the first I ever tried on my very first iPad, and I have downloaded it on every iPadOS device since. It changed the way I do all financial calculations. I am just so happy to be able to support this company in any way, even just with the annual subscription to this app. Thank you for designing something simple, practical, and completely functional..Version: 3.6.6

An Effective #2...I usually accomplish my calculating needs with a TI-30X-II-S, as it is ideal for the common trigonometry that pops up in daily life. However, if I find myself without it, yet have my iPad, then this calculator app is often the next logical option. It performs all the functions necessary with an acceptable visual interface, but my preference is for the feel of a dedicated device that almost becomes an extension of my hand. The physical touch of the entering data on a touch screen is less appealing to me, as I have to look at the screen to avoid input error; the TI allows touch familiarity, much like when operating a TV remote. For casual use, it is a solid option. For my preferences, it is my second option... for now..Version: 3.5.4

Review for calculatorI absolutely love that it gives a history. It is the first calculator that I have used that I can check to see if I entered things correctly. Plus it has a back arrow to correct mistakes if I notice them right away. I may have made an error, or sometimes, I forget to press the function key of adding another item and therefore two things get all run together. Any other calculator, I would have to start all over, but not with this one. Thank you for a couple priceless improvements. I now want to use this calculator over any other one or even an adding machine..Version: 3.6.2

Functional, but...A huge improvement over the stock calculator, but, as other reviewers have noted, the ad coverage is annoying. I could deal with the ever-present banner at the bottom, but the full-screen pop-up that just recently started completely disables the app, and the tiny kill-switch “x” in the corner is—by design, of course—virtually impossible to engage, frequently making it necessary to exit the app and restart in order to restore function. I’d happily pay a one-time fee to get rid of the ads, but the option isn’t available. Although I do like the app, the advertising interference has me looking for an alternative..Version: 3.2.6

Finally a calculator that shows the historyNow I don’t need to purchase and adding machine. I’ve been planning on buying one for a while because I really want to see the history of my entries, but this is even better; no need to print it out and buy/waste paper adding machine tape. No need to even buy an adding machine. I know that there are other calculator apps which show the history in some inconspicuous location if you know the secret password and cross your eyes just so, but this one is so much more convenient. The history is up front and center without having to say the magic word. Well done!.Version: 3.4.11

Too many ads.I’ve used this app four 3 years or so. I’ve come to the App Store to find a new calculator app to replace it. I don’t mind seeing ads on a free app but this has gotten out of control with multiple full screen pop ups that interrupt my calculations. I guess they need to make money but I read all these reviews about folks deleting the app and it seems to me they are going to lose more money than they make. If you are looking for a calculator app I suggest you scroll past this one and keep looking..Version: 3.8.10

Just a normal calculator.I just needed a calculator. They don’t seem to make them anymore. They are all so complicated. This is really easy to use. It keeps track of what you have recently done so you can your work while you are using the calculator. Kind of a safety measure if you get interrupted while using it. Cool 😊 It also has a scientific calculator for those who need that you can switch too that one if that is what you need. I really appreciate that they are separated. Thank you for thinking of all of us..Version: 3.2.10

The best calculator app!This calculator app is absolutely the best. You can do scientific functions or basic math it even allows you to use the memory keys. There is also history section that keeps track of all the calculations just in case you need them. End it also shows you in list form everything that you were typing in so you can make sure that if you make a mistake you can fix it fast. It’s simple and easy to use. I also really love the huge buttons..Version: 3.2.2

Great calculator… butIt really was a nice calculator, it was my favorite until recently. There has always been an ad at the bottom of the display, which was fine. They recently started large pop-up ads that are very intrusive, and often make me have to restart the app. The only way to get rid of the ads is to buy a yearly subscription. Yep, that’s right, they want a yearly subscription for a calculator. I would happily pay a ONE time fee of $2.99 for a calculator app, but anything more than that is simply ridiculous in my opinion..Version: 3.6.7

SIMPLE, REFRESHING, UNDISTRACTED PERFORMANCE…This app does exactly what I need done without the dizzying options that some calculators come with and without the overly disruptive advertisements. I’ve used this calculator for years having been disappointed with the bombardment of distractions on other calc. apps. This app stays on my home screen dock and is placed there any time I get a new device. Developers occasionally create apps that are worthy of being “Go To’s.” This is one of them. That about “SUMS” it up.😉.Version: 3.6.1

CalculatorI guess I have to actually write something for the "send" option to light up...and it did, of course. Since I'm here, I might as well let you know, I've been using this app for 11 years and it works. However, when I was in college I had to download another app to do linear equations. That was the only time I needed a different calculator. Otherwise, this was/has and continues to do my "every day math" quite efficiently..Version: 3.6.4

Cluttered = Confident + ComprehensiveAt first I didn’t enjoy this app because it is visually cluttered/confusing. As I used it each day, I appreciate the storage area on the left side which can be fully deleted or delete individual calculations. I am on a 1200 calorie/day diet and I use this to determine the calories for each meal then transfer the result to another calculator. If I had to select only one calculator in the App Store, this would be the definitive one..Version: 3.5.18

Slow audio feedbackI like this app and now use it instead of my old stand-alone calculator, and would prefer to deduct only a fraction of a star. The only flaw is that the audio feedback lags behind the actual keytouch just enough to be noticed. I can touch a second key by the time I hear the click of the first. This is confusing because I have to look up to make sure the first touch registered. I like having audio feedback, but may have to silence it unless future updates reduce the lag time..Version: 3.2.16

Holy guacamole!I am not exaggerating in the slightest this application has changed my life for the best. Before, I had trouble adding, subtracting, and dividing (I’ve always had a knack for multiplying so I’ve rarely had issues in that front) but since this app, I have been just absolutely crunching the he*l out of some numbers! This is so much worse than the built in calculator application. PS if Meghan is reading this congratulations on getting married last night! From nay love, Susannah.Version: 3.4.4

Basic calculator plusI have enjoyed this app for several years. I only use the basic functions, but if you need more then it is available. Personally I detest algebra and have no use for scientific functions. Basic is fine for remodeling and landscape work. Keep up the great app! Really really recommend this app. Even without the premium it is GREAT! Thank you and a shoutout to the developers..Version: 3.9.1

CalculatorThe calculator is the Best calculator you can ever find. You can do any math equation you could ever find. I like the history part because it shows you that you don’t does question and you can see if you already did it. You can even learned from it. Like your parents can’t give you a list of math equations. And you can first opened and then check if you did it The question right find out what you can do.🙂.Version: 3.2.14

CalculatorI am so grateful that I am using my new Calculator and I hope that this will come very handy in me. And I hope that this is the best way I can use this all the time if I need too. And I have been using it with my phone to. It is very good to do that on my own time and is very good to keep and part of all of my records and receipts and checking. I am keep it that up and all it is good..Version: 3.8.8

Beware of ads!This calculator is a fine app, and I use it all the time. The number buttons are large and the printing on them is clear. It works quickly for the very simple uses I have for it. Actually, the only things I don’t like about it are the ads on the bar below the calculator. I know that I have to put up with ads in order to get a free app, but they are as intrusive as they can possibly be, short of causing me to throw my iPad against a wall. The price I pay for frugality!.Version: 3.6.4

The bad appThis game will help you cheat well it’s not a game but it will help you so that’s why I’m getting a three star but it will also help you learn so that’s why I gave it to start well not exactly this game I don’t know why I keep saying game but this app is kind of boring so you might not want to download it because it’ll help you cheat if you’re just trying to do a math problem and you have your iPad right next to you then you will just go on this and cheat so that’s why I think this is kind of a bad app.Version: 3.5.17

Easy, Effective & Minimal AdsI don't need lots of bells and whistles, so this suits me fine. There are several extra functions available, yet they do not complicate the visuals I see. Being able to see my calculation history, and clear it when I wish, is very useful. This is a solid app. I have used it for several years, and have never found a need to look for anything else..Version: 3.2.7

Best app everIt always gives me the right answer and it never ever glitches I was looking for an answer since I didn’t know the answer to it and it gave me the answers super fast I only have one complaint whenever you tap on the button it takes like two seconds to show on the screen but that’s my only complaint besides that amazing app.Version: 3.4.12

Love the app however.I have had this app for a year or so. I just renewed a year subscription. I had to log off my phone and back on and even though it shows in my subscription it’s not recognizing that it’s a purchase. I tried the restore purchase it tells me an error happened to try again. Tried several times with no success. Love the app and use it daily but won’t pay another subscription. Disappointed..Version: 3.8.2

Nice calculatorJune 3, 2019 - Thank you for the recent update which corrected the decimal point. Really appreciate the calculator. This is a really nice calculator. Lots of extras; however, for my purposes - I only needed a basic calculator. My only complaint are the pop up ads which get in the way when I am trying to work. I don’t mind the scrolling ads at the bottom..Version: 3.3.1

Great calculator but with ads.It's an excellent calculator. I particularly appreciate the history function that let's you re-work or add in previous formulas. The advertisements do throw me off though and I'm definitely not used to seeing pop ups while working on math but I understand the need to collect $$. If I weren't so cheap I'd buy the full version with no ads. ~R..Version: 3.2.2

How do you unsubscribe?I tried to use this App the other day, I was in a hurry, it would let me use the app unless I subscribe. Now I can’t find how to unsubscribe. I tried restore, and it says I didn’t make a purchase?!! But I’m getting charged for it. And the ads are still on the bottom of my calculator. I want to unsubscribe..Version: 3.8.2

Developer needs to offer a one time purchase feeI really like this calculator app. The ads can be a little annoying. I would actually purchase if the developer offered a lifetime one-time purchase fee. I am not paying any ongoing subscription fees forever so I will just put up with the ads I suppose for free. LOL.Version: 3.9.1

Calculator’ ReviewThis calculator app functions greatly, is easy to use, has anything and everything that I would want in a calculator app and much, much more. This is why giving this calculator app a five-start rating is a no-brainer. Thank you ever so much for making such a wonderfully outstanding calculator app. Please keep up the excellent work too..Version: 3.4.4

How can I purchase for this appThis is the best calculator app i've ever used. Wonderful job, the memory is the most important part. Good job guys. I want to pay for this app because i'm sicking of Ads. Btw, when you use it as a side app on ipad, when click on ! icon and show Ads, it cannot be close (when in side mode), you have to switch back to this app, and hit X on the right coner for close. It's sometime drive me crazy..Version: 3.2.5

Basic calculatorI purchased the yearly subscription - but it doesn’t work on my other devices - is there a reason for this? Or do I need to do something to allow this calculator to be adds free on my other devices. Note: The pop up adds are incredible annoying. I guess you’d call it a good tactic just keep annoying the people that have this app to get them to buy a yearly subscription..Version: 3.6.7

Excellent calculatorI have been using this calculator for over a year and I have not experienced an problems with it. I particularly like it that I can see the numbers and the operators that I have entered. This allows me to verify that I have correctly entered the data, and hence gives me confidence in the result. I also find the history function very useful..Version: 3.2.10

Best freeware calc, bar noneFull featured and visually appealing..Version: 3.2.14

Can be betterIt can be better with a note pad on the side and a printable tape..Version: 3.5.17

CalculateI use the calculator because it has history.Version: 3.9.0

AdsGreat but ads can be way too long.Version: 3.9.1

Pretty goodHonestly not that bad for a Calculator. Nothings wrong with it I love it I only use it sometimes but it’s good for a Online Calculator..Version: 3.8.10

Too Many AdsHave used this calculator app for many years. In the past, you would just see an advertisement when the app gets launched. Lately though, the advertisement is becoming intrusive and they will even show up in the middle of calculation. It was once a good app but frustrating to use because of the ads..Version: 3.8.10

Une calculatrice explicite grand formatJ'aime bien la calculatrice en format scientifique, elle est facile d'usage et je ne discute pas les résultats !.Version: 3.8.10

It’s goodWorks great.Version: 3.8.8
