This calculator looks plain and straight forward, which is why I initially liked it… but the UI is off in some places and bleeds into the top bar of my year-old iPad. Had trouble closing the sliding history window too and had to force close the app each time I tested. Doesn’t seem well coded or tested to me. It also just asked to know my location when launching it today… I decided that there is no real reason a calc needs to know that, It felt scummy. I just uninstalled it and will keep looking. Hope this helps someone. **Developer response:** We understand your fears when granting extra access to our app but we strive to always make our apps as easy to use as possible. ### 3/5 — Made to buy AGAIN *2021-09-13, version 5.2* Bought this right after I got my new IPad air. Installed it, loved it… then recently it went all white! There was NO app showing at all when I opened it, just a white screen. So I figured there must have been a glitch and thought I would delete it and reinstall but it wouldn’t recognize that I purchased it even though it said on my screen. I had to find a new version for 2.99 and install just to return to what I had been using all along?! That’s not right. **Developer response:** We appreciate if you could contact our support service (support@apalon.com) with a more detailed description of the issue so that we could try to resolve it for you. Thank you in advance for your cooperation! ### 2/5 — I Paid for No Ads... but *2020-02-22, version 5.2* OK - I really liked this calculator; however, I paid for no ads. While they are not always present, when the history window is open you have an “X” to close it under an “i” for info. Which causes accidental touching of the “i” very easy! That brings you to the Ap Developer’s other Aps to get. In essence and Ad for their other products. Very frustrating and will be requesting my money back. I like to have my history open to see my math. **Developer response:** Thanks for your feedback. We appreciate your comment and will consider it while working on future versions of the app. In case you have any ideas on how the app could be improved - please let us know at support@apalon.com. Thank you in advance for your cooperation! ### 2/5 — Changed all of a sudden *2019-12-14, version 5.2* Been using the pro for long time w/o the advertisements, all of a sudden , just over nite I was trying to use this morning the numbers on the keypad are very large, cannot see the calculations screen. Rebooted iPad but had no effect, deleted from desk top, reloaded it now I have very large numbers with framing advertising. Can not make the calculator fit the screen like it was yesterday. My IOS 13.2.3 is what I use , I cannot provide more specific info, other than the above description. Had used it the nite before when I went to use the calculator it was very large with only a few numbers visible on my screen even in landscape, again I tried the steps above before I deleted it and reloaded it. Had to pay for the pro again to get rid of the advertisements. **Developer response:** Thank you for reaching out. It's important that we understand how the issue occurred. Please, can you provide more details on this matter to our support service (support@apalon.com)? We are willing to help! ### 4/5 — Price gouging App? *2018-10-12, version 5.1* I would like this App a lot better if I hadn't had to pay for it every 4th or 6th or 9th time it upgrades!!! I guess this last time it did at least add a couple of functions it did not have before..... ### 5/5 — Go Paid *2018-08-12, version 5.1* Calculator Pro is a good app. Recommended pay version to avoid games to play that keep coming up. ### 5/5 — Satisfied *2018-06-20, version 5.1* I use this calculator for quick calculations. It is always at my fingertips and I am quite pleased with it! ### 5/5 — Best Calculator App for iPad *2018-05-19, version 5.1* Money well spent on this one. No crashes and it's very simple to use. I do hope that there could be an update where users can disable the recent calculations. Thanks. ### 2/5 — Multi tasking how???? *2018-05-03, version 5.1* Made this purchase based on advertised picture of calculator along side a recipe/shopping list. There is no explanation once purchased how one would go about doing just so. Contains a number of calculators but no instructions. Picture was misleading. The price for the calculators alone is reasonable but I was looking for that extra feature. ### 5/5 — Great iOS calculator *2018-04-30, version 5.1* This is an outstanding app. It’s easy to use and performs all types of calculations. Highly recommend it. ### 4/5 — Very good all-around iPad calculator. *2018-04-28, version 5.1* Makes great use of space provided by iPad and has a wonderful conversion function. Plus pro version gets rid of the advertisements in the free version and it has some nice skins. ### 5/5 — Nice *2018-03-05, version 5.1* I like how it is easy to see and check your work before totaling with long calculations. ### 2/5 — Watch out while entering exponential *2018-03-04, version 5.1* This calculator app does pretty much what it should, but I encountered an issue where when I was entering exponentials, I have to enter the sign of the exponential after the value. For example if I want to type 1E-3, I have to type 3 before the minus otherwise a 1 automatically appears and I’ll have 1E13. I find this to be rather unusual and for a calculator app such quirks can lead to lots of problems. Hope the dev will fix this and I’ll change my rating. **Developer response:** Thank you for your feedback. We appreciate your comment and will consider it while working on future versions of the app. If you have any further suggestions or ideas - please let us know at support@apalon.com. Thank you in advance! ### 5/5 — Great Calculator *2018-02-09, version 5.1* I have used the free version for about two years and now I’ve purchased the premium version. I think that, for me at least, the few bucks was worth the cost to rid the app from the few advertisements. ### 5/5 — Calculator Ap *2018-01-06, version 5.1* Numbers are large, and it is intuitive to use. Great to have it whenever I need it while on IPad. ## Most critical reviews (10 lowest-rated) ### 1/5 — JUST TERRIBLE *2019-11-21, version 5.2* This thing worked good for a while and then the graphics blew up! Could only see part of the calculator on the IPad. I latest IPad OSX and did everything possible to delete the app then shut the iPad down and restart reinstall. It works for a little then repeats the mess. I reached out to the developer and sent the, a screen shot and they suggested stuff I already did. They had no solution and don’t apparently care. I would get it no stars in I could. Stay away from this! **Developer response:** Thank you for reaching out in the comments. We are aware of the issue and already doing our best to fix it. We apologize for any inconveniences and hope that you can wait till we get a proper version ready. Thank you for your cooperation! ### 1/5 — AVOID THIS MALWARE APP *2019-02-18, version 5.1* Don’t install this app. I installed it on my new iPad and I started to get intrusive pop ups. The Safari on my iPad was useless with the pop ups redirecting my browser to some scam site asking me to take surveys with the promise of winning an iPhone or iPad. You cannot go back to the site without closing the browser. Apple needs to pull this app from the App Store. I had to uninstall and reboot my iPad to stop the pop ups. I read the privacy policy and discovered they’re collecting a lot of my private data (email address and password as well as the use of my camera at anytime, and Facebook data) in exchange for the use of this app. The agreements also give them the rights to ask us to take surveys. **Developer response:** We would appreciate if you shared information you have about such advertisements, including screenshots and links if appropriate. We will do our best to find the unscrupulous ads provider and to prevent such situations in the future. In case you still have questions about your privacy or data, please don't hesitate to reach us at support@apalon.com at any time. Thank you in advance! ### 1/5 — Advertisements in paid version *2018-08-28, version 5.1* I paid for the pro version, yet I receive advertisements from the developer about other apps, which they make and sell, that they think I might be interested. What I am interested in is using the app without annoying marketing distractions. Disappointed. ### 1/5 — Complaint *2018-03-09, version 5.1* I paid for this calculator so I wouldn't have ads. Well, there are no outside ads but I keep getting notifications from you to upgrade or whatever. I just want a plain calculator and that's it. I don't want to upgrade, change skins, nothing! I'll be so glad when I can find one. I am on my third and it is still the same thing over and over. ### 1/5 — Ads ruin experience - even after PAID FOR UPGRADE *2018-02-13, version 5.1* I wanted a regular old calculator with no ads. I used the free version, and it was constantly interrupted by ads. I paid for the upgrade - STILL has pop up ads. And I’ve seen multiple reviews say the same thing. I am a very generous reviewer, this may be the first 1 star review I’ve ever given. But a simple calculator that you can’t concentrate while using because of pop up ads defeats the point and ruins your work. ### 1/5 — STILL Not compatible with ios11, out for money only *2017-11-08, version 5.0* Bait and switch: Agree with other reviewers: yes with paid version there are still popup ads when you open, and yes this is a simple app, which cost more than similar apps..but my other very complicated apps were updated immediately for ios11...this one we are STILL WAITING FOR..where is the support? Well guess what? Their ad-bloated free version was updated almost a month ago. Unreal. It took forever just to get a percent key in side by side. Sad I spent money on this greedy developer. **Developer response:** There should be no ads in the full version of the app. We’ve checked the issue on our side and everything seems to be correct at the moment. Also please note that we are already working on fixing the issue with iOS 11. Please do not hesitate to contact us if this will happen again. Drop a mail at support@apalon.com and we will do our best to resolve the issue. ### 1/5 — Ads are prompted upon opening the app?! *2017-11-02, version 5.0* I BOUGHT this app so I could make calculations quickly WITHOUT being interrupted by ads. However, very often I have to click out a pop-up window that is prompted whenever I start the app. Absolutely ridiculous for a app I PAID for... Apart from this atrocious marketing scam, this app isn’t even compatible with iOS 11’s multitasking! There are a lot of calculator apps for iOS which actually function with iOS 11 and don’t incessantly advertise at you once you bought it so steer clear of this rip-off. Note to Developer: I’ve seen other reviews complain about these pop-up ads on the paid version but you seem to insist that they must still using the free version, this is NOT the case. On the PAID version of this app, you have programmed it to often times create a pop-up (not a banner) when opened to advertise your companies products. It’s dishonest and offensive to your customers whom are told they are purchasing an “ad-free” version. **Developer response:** Thank you for the review. We're very sorry for this inconvenience and will do our best to make the app more useful and user-friendly with it's future updates along with the iOS 11 multitasking support. Thank you for using our app! ### 1/5 — not worth it - stay away from this developer *2017-10-20, version 5.0* purchased the pro version. worked fine until iOS11 was released. as stated in other reviews here, the bug is in multitasking mode. you cannot use the app in floating multitasking mode, something that is very problematic. most users will want that functioning properly. i reported this to the developer in september 2017, was told a fix was coming soon. i reported again in early october 2017. was told a fix coming soon. i am checking now, no bug fixed and the month is coming to an end. may i remind the developer that we paid a rather elevated amount for what amounts to a basic, simple app. the same amount buys apps that require lots, but lots of more work than this calculator app. the fact that developer cannot fix a simple bug that truly limits the use of this app is unacceptable. simply put, this is not a priority for the developer. it is just a way to extract some money from you. stay clear from this, aim for other apps that the same if not more. i am deleting mine, wish i could get my money back. the developer does not deserve it. and no, i usually do not write reviews. **Developer response:** You can now download the latest update of the application which fully supports the Slide Over mode. We hope you enjoy the app and please let us know in the comments if you experience other issues with the app! ### 1/5 — Paid version shows ads 😡 *2017-08-27, version 5.0* Absolute scam to pay for an app and then be repeatedly prompted to download additional junk apps. I chose to purchase a non-free calculator app specifically to avoid ads and this is what happens. Stunningly awful choice on the developer's part. As a calculator, it's fine. Nothing special. What I expected, except I expected no ads. ### 1/5 — Lag *2017-08-17, version 5.0* There is actually a frequent noticeable lag (~500ms) between hitting a number and getting a response from the app. Also, the paid version offers no way to remove the icon that does nothing but advertise your other apps. How do I request a refund? Apple makes this difficult. ## Most praised reviews (10 highest-rated) ### 5/5 — Please make a version for iPhone! *2022-06-01, version 5.2* Great app. Clean. Well worth the money to remove adds. But why is there no iPhone version? The iphone calculator is too basic. I would love to have the Calculator Pro app on all my devices. I can't find anything as good as this app in the app store for iPhone. ### 5/5 — Buy *2020-07-18, version 5.2* I’ve been using this APP for about 1 year 6 months and today paid the $3 bucks to never see those AMAZINGLY LOUSY adds again. The computer calculator... here feels like it’s Perfect for The Pro. You will need it, trust me on that! ### 5/5 — Calculator Pro plus *2020-04-13, version 5.2* Pretty is only a small part of the faithful useful app I find when I click here. I have been thankful every time For having made the decision to buy this. ### 5/5 — Calculator *2020-01-21, version 5.2* It works has many more features than I need. ### 5/5 — Great calculator *2019-11-30, version 5.2* I’ve used this calculator for several years and have not been disappointed. ### 5/5 — Great calculator app! *2019-11-18, version 5.2* Works very well, no issues after months of use. Used on my phone and tablet both. ### 5/5 — CALCULATOR *2019-11-12, version 5.2* Calculator is easy to use and what I like best is that the top line keeps a list of all numbers you are adding together. It makes it easy to see if there was a mistake. Good job program designers Thank you ### 5/5 — Great app, until buttonless iPad Pro *2019-03-07, version 5.1* I’ve used this app from my very first iPad, and have always had it on my front screen. Still do, but with the 2018 iPad Pro, the task bar at the bottom obscures the bottom buttons in most of the skins while in landscape mode. Please adjust the orange and brown skin to fit. Great app otherwise, and love the conversions. **Developer response:** We are aware of the issue and already working on it. We apologize for any inconveniences and hope that you can wait till we get this fixed. Thank you! ### 5/5 — Best calculator *2018-11-09, version 5.1* I love this calculator. Easy storage of each calculation makes checking your work a breeze. I wish I could find it for my iPhone. ### 5/5 — Calculator for iPad or iPhone incredible *2018-08-18, version 5.1* I’ve been using this calculator for years The check on my pricing tips etc. etc. very helpful kids for school five stars --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
