Unfortunately it has a very frustrating quirk where you have to swipe up from the bottom of the screen twice to exit the app or switch between apps. This makes the app unusable when I need to do some quick calculations while switching back and forth from another app. The only other apps I have seen this happen with are games where you might accidentally swipe up near the bottom of the screen by accident, but I don’t think that is an issue for a calculator, so I’m not sure why it happens here. ### 4/5 — Almost perfect *2025-06-13* my only gripe is that it hides the home indicator, which makes leaving the app two swipes instead of one. Please set prefersHomeIndicatorAutoHidden to false ### 4/5 — 現iOSだと操作が…… *2024-03-01* とても高機能かつシンプルで使いやすい！ だけど画面下部をタップするとページが左右移動するので、現iOSのホーム画面操作と同時に誤操作してしまうのが玉に瑕。 ### 4/5 — Misses % *2023-09-08* Would give 5 stars if it had percentages We have to type 100 * 0.05 = 5 100 + 5 = 105 If there was a % we’d just have to type 100+5% ### 4/5 — Best calculator app, but needs modernized *2022-07-27* On newer phones with swop gesturing the app has become very clumsy to use. Hasn’t been updated in two years. Otherwise this is the best conceived basic calculator app available. I would’ve given five stars if the developer were a little more responsible. ### 3/5 — Needs an update *2021-10-13* This has always been my favorite calculator on iOS, but it’s buggy and needs an update. Swiping up from the bottom of the screen to exit the app or switch between apps doesn’t always work, it just scrolls between calculator pages. This makes the calculator unusable when I need to do some calculations and then switch back to another app. ### 3/5 — Please fix *2021-02-09* I like the app a lot but can we fix the swipe up problem where it doesn’t change the screen page? This has been a problem for a long time. Loosing my patience- Trying to look for a new calculator app! ### 3/5 — Plot of sin(x)e(-x) is not correct. *2020-05-07* Plot of sin(x)e(-x) is not correct. It should reach zero when x is sufficiently large but it’s not on the plot. ### 5/5 — 惊呆了 *2020-04-23* 挺不错 ### 5/5 — Çok iyi *2020-04-23, version 5.3.1* Çok işlevsel ### 5/5 — 非常棒的软件 *2020-04-23* 功能特别齐全！ ### 5/5 — Good feature *2020-04-22* Good math using, expect to have Hex,Oct, Binary value conversion display ### 5/5 — The best calculator app I’ve known so far! *2020-04-09* The flexibility of editing input and recycling output is what makes this app excellent. Kudos to the developer for such great app, I rarely touch my bulky Casio thanks to you. ### 5/5 — Use this calculator since first release *2020-01-05* Not big concern, but on iPhone 11 top part of answer is not visible, because cameras module. ### 5/5 — Best *2019-05-30* Не хватает только Apple Watch ### 5/5 — Simple, easy to use *2019-04-20* Nice app. Meet daily needs. ## Most critical reviews (10 lowest-rated) ### 1/5 — Mac doesn't accept keyboard *2024-04-13* Please make the keyboard available ### 1/5 — One star for outdated UI *2021-11-17* The UI needs an update to work better with switching apps with bottom swipe. A huge part of a calculator app is ability to switch back and forth to other app to enter numbers or for quick calculations. The UI is outdated and was designed when iPhones still had a home button. With newer phones attempting to switch app would result in accidentally pressing numbers or switching to a different calc mode. It’s mildly frustrating. ### 1/5 — Does Not Work- DO NOT WASTE YOUR TIME *2021-04-12* This used to be in the market now it’s not reusable one issue is not with me captivating personality but instead with the application essentially it is almost impossible now to traverse mom life by swiping up on the snap besides losing is obviously have a little interesting quality that this is been issued for well over two years now I wanted nothing more than to continue a d use this app but at this point i am a day with it and will be reportig this app that DOES NOT WORK wih ios to the Apple store so they can review ### 1/5 — Please fix. *2020-07-08* Home bar overlaps button below. Therefore, it often malfunctions. This is iPhoneXs. ### 1/5 — Junk *2014-07-11, version 4.6* Don't waste your time with it. ### 1/5 — Джинса! Рейтинг натянут *2012-10-22* Один из более 9000 бесполезных калькуляторов. Глупые 9 или сколько там экранов с режущими глаза фонами. Враньё: не поддерживает комплексные числа. Рекомендую мазохистам. Интерфейс никакой. ### 1/5 — More like a downgrade *2012-08-24, version 4.1.1* What happened to the old app. That was the main reason I bought this app. If you're thinking of buying it, consider a different app with more functions. Being a student in a calculus class I like to toggle back-and-forth on my phone and calculator. This can't even do cubed roots! It's more of a mix of apple's stock calculator mix with SOME graphing features. Spend your money elsewhere. ### 1/5 — Undo this 'upgrade'! *2012-06-14, version 4.0* My son upgraded this app and warned me not to do it. The original version was clean, intuitive and had a great display. It is just what I want in order to easily plot 2d and 3d graphs. But then they totally changed it. Now there are several different screens that you need to search through in order to find the functions you want. The general look of it is juvenile - which isn't terribly important but I just wonder why they decided to completely renovate the interface. Thankfully, I did not upgrade the program because of my son's warning. But now I have to individually update all of my other apps in order to prevent this one from changing. I guess if the old version doesn't come back, I'll eventually just delete this one and try some other app ### 1/5 — An upgrade disaster *2012-06-10* Can I have the original version back? The upgrade is awful, now its more like a childs toy and it is much more difficult to use. I have removed it from my iPad ### 1/5 — Very Misleading! *2012-03-20* This app CANNOT create complex graphs! The 'uses complex numbers' part of the description only applies to calculations... Completely useless, as there are many free apps which produce standard graphs - just wasted £2.99! ## Most praised reviews (10 highest-rated) ### 5/5 — Love it, but *2026-03-10* I’ve used this calculator for years and I love it, but please update it for iOS 26, just make it easier to swipe in and out of like others have asked for, don’t worry about changing anything else! Do that and give me an option to tip. I would gladly pay for this app again after all these years! ### 5/5 — No Ads - Side by Side Calcs *2025-09-26, version 5.4* Simple, no nonsense calculation! Love it! ### 5/5 — It’s like a Christmas gift *2025-01-22* I’m so glad that the dev updated the app and get it back to the App Store. I never expected that they ever update the app again. Moreover, they finally fixed the annoying glitch when page switch while swiping to another app. The best calculator ever. Thanks and keep it up. Don’t abandon the app again 👆🤝 ### 5/5 — So glad your app is back in Au!! *2025-01-22* I love this calculator soo much, and was so disappointed when I couldn’t get it on my new device…till now! This is the easiest and most functional graphing calculator I’ve used. Thank you for this wonderful app. ### 5/5 — Excelente, mas... *2023-12-28* O app é o melhor da categoria, mas precisa de atualização para os layouts mais novos dos iPhones. ### 5/5 — 太好用了！ *2023-12-21* 不仅可以保留4次计算，并且还能写很长的算式。还可以来回切换对比结果。很方便！ 画二维、三维图也是很有意思！ ### 5/5 — отличное приложение! *2021-09-29* отличное приложение! пользуюсь очень давно. идеальное решение👍 несколько калькуляторов в одном. ГЕНИАЛЬНО! перешел на iphone 11 и тут выявился баг. в нижней части экрана, при смахивании приложения вверх, оно не сворачивается а переключает на другие режимы программы. разработчики, поправьте пожалуйста save area. ### 5/5 — 好用，希望有中文的，这样看着更舒服 *2021-08-23* 希望可以出中文的，这样看着更舒服 ### 5/5 — Best calculator app. Had it for years. *2020-09-18* My only complaint is on the newer iPhones, the interface needs an update. When swiping up to close the app or switch to the previous app, it always changes the calculator ‘page.’ it gets rather annoying when you’re referencing numbers in another app, switch back to enter them and have to swipe back to the number pad. It’s a minor complaint and the app is best in class. ### 5/5 — Excelentemente ótima. Simples assim. *2020-05-11* Parabéns aos Desenvolvedores pela prática, bonita e extremamente útil calculadora. As várias calculadoras de diferentes cores e funções são TOP. Muito simples sua utilização, seu tutorial e operar ou trabalhar com ela tem sido bem agradável e prático. Muito boa mesmo. Pensaram em tudo e puseram em prática. 100% de aproveitamento sem perda de tempo ou complicações matemáticas. Obrigado pelo “presente” Desenvolvedor!
