User Reviews for Calculator #
Used to be great, now a money pit
I used to use this app all the time, it was wonderful and so helpful. There were ads and a few types of equations were “advanced” and you had to pay to solve them, but that was ok because it was overall a great time saving app when doing Algebra. I deleted it for a while, but now I’m taking pre-calculus so I thought this calculator would help cut back time by doing the smaller parts of equations quickly. This did not happen. To my dismay, most algebraic equations are now “advanced” and require subscription. 3x=6 was considered advanced. And there’s still ads everywhere. So they took away the best free features but left the ads? This is ridiculous. I understand that running an app requires money, but this is too far.
Great calculator ruined by interruptive ads
I have been using this calculator since 2014 and it has been great and my preferred calculator. Unfortunately, one of the updates earlier this year(I cannot pinpoint the update), changed the way advertisements work. Before, you would have advertisements sit on the top being visible but not getting in the way of your work. Now in addition to this ad on top, you would have an ad pop up covering your entire screen and completely interrupting your work, which is very annoying and now frustrating. I have decided to move to Calculate84 for this reason. Paying up for a paid version is not guaranteed to fix the problem since they do not list “no ads” as a benefit. Unless the developer change back, I cannot recommend this otherwise great calculator to anyone.
Brilliant app, thanks for holding off on the ads until I got use from it
Just wanted to say thanks for holding off the ads until I had used this app for a week or two. Great little piece of technology. Bought the infinity calculator earlier today ... Looking forward to it being worth the purchase. Gotta say, those full page ads were super annoying, but I get it. You made this thing a demo for the infinity, which is still CHEAP. Thanks, developers. I hope you carry on well.
Advertisements are awful
This calculator would get a 5 star review from me if it didn’t have ads with sound that come up randomly. This makes this calculator useless if I am using it in a classroom, since I have no idea when these stupid and intrusive advertisements will interrupt my studying or the rest of the class. In fact, I was interrupted from my studies just now from an advertisement, and I decided enough is enough and wrote this review with the hope that the devs will remove the intrusive and interrupting advertisements. I’m fine with the banner ads, I understand they need to make money, but having these ads pop up in your face and making sounds interrupting classes or studying is just way out of line. If the devs remove the intrusive ads I will change this review and give 5 stars. Functionally, it works great, the display is awesome with a history of previous calculations to make multiple operations easy. It has all the functions of a scientific calculator that you would need. But
great for homework/online students
Because of schools closing due to COVID-19 it’s been hard to adjust to online learning especially because i don’t have all of the resources and supplies that i would have at school regularly. Especially in math because i don’t have the money to buy a nice calculator and the school doesn’t provide any. This really saved me because it had all of the tools needed to help solve and understand the stuff that we’re working on and learning at this time. I could just use a website on my computer buts it’s way easier and more convenient to have it on my phone rather than switching the tabs back and forth :)
Great calculator, bad flaw
This calculator is AWESOME, best free calculator on the App Store that allows you to actually do useful stuff without paying (more advanced features are available to buy tho, and for a one time payment and not just a stupid subscription model!)However, in the recent update they added a sliding animation when moving between the two calculator screens. This is VERY ANNOYING and disorienting, especially when trying to do fast switches. PLEASE ADD A SETTING TO TURN THIS OFF! THE BIGGEST FLAW IN AN OTHERWISE AMAZING APP
Obnoxious Ads
I prefer this app over the native calculator because of its extended functionality and ease of use. In fact I can't even remember the last time I needed to use the native app. I also especially love the history feature!Update: I understand the need to fund an app hosted by Apple, but this app was far better when random ads didn’t just pop-up over the entire calculator! I can live with a small ad banner up top or down below, but not with pop-up ads. Unfortunately, this is where I draw the line and ended up uninstalling the app.
Great calculator, way too many ads
Don't understand why a calculator should be monetized. Any time I open the app for a quick calculation I have to sit through a 5 second ad, and the entire time I use it there's a banner ad at the bottom. The worst part is that the ads have been increasing. I got this app years ago, and there were ads but only banners if I remember correctly. Recently it was video ads were added and play every few calculations. Makes using the app so much more of a hassle than it should be.
IU design and Options
This is just a fantastic calculator. The UI and the functionalities are just what you need. And the convenience is unquestionable. Upgrading to pro is also worth it. Although I haven’t done it because I am just using it for some number punching and algebra. But if there are students out there taking advanced math classes, this could be really good. Also, given the fact that iOS calculator is so minimalistic that now it’s no more interesting but just annoying.
Absolutely Excellent
Before retiring I was An intercontinental ballistic missile designer. Mathematical calculations were my daily bread and butter. This calculator can do, for free!, what our most expensive calculators could do. I am amazed that such a powerful calculator is now being offered at no cost to anyone who needs a small hand-held calculator. Thank you so much for making this calculator available. I highly recommend this calculator. (The only down-side to this calculator is that it does not use reverse-Polish notation which requires fewer key strokes. But no one uses reverse-Polish nowadays anyway, much less knows what it is.)
