The SAVE button just disappeared. Help. ### 4/5 — This is my go-to calculator *2021-09-03, version 3.9.2* This is my go-to calculator ### 4/5 — Calc it *2021-03-12, version 3.9.0* Nice calc ### 3/5 — Okay for arithmetic *2020-01-29, version 3.8.0* Fine through maybe a junior high school level, but not really an advanced scientific calculator. And for my money, any real calculator needs RPN. Nice colors, though. ### 4/5 — Great app *2019-10-21, version 3.6.0* Easy to use, lots of functions but looks very neat and simple. recommend! ### 5/5 — Great app you can control a lot of things *2019-01-18, version 3.6.0* Will be the best if the results could be in fraction form, is this possible? ### 5/5 — Great! *2019-01-17, version 3.6.0* Simple, pretty, just works! GET IT!! ### 5/5 — WOW *2019-01-10, version 3.6.0* This is an awesome calculator and lots of nice options. AppAdvice had notified me of price change so decided to give a chance and I really like it. Thanks to the developer for making a very useful app. ### 5/5 — I love it *2019-01-09, version 3.6.0* I like it ### 5/5 — Amazing calculator *2019-01-09, version 3.6.0* It is very convenient to insert several parameters to get the results. This calculator would help you lead easier life. ### 5/5 — Astonishing *2019-01-08, version 3.6.0* I prefer it over actual iPhone calculator app. ### 5/5 — Useful and beautiful! *2018-12-06, version 3.5.3* Love the way to show and rename history and custom font sizes! ### 5/5 — The best calc！ *2018-11-26, version 3.5.3* Getting better and better! ## Most critical reviews (10 lowest-rated) ### 1/5 — Glitchy *2023-05-24, version 4.1.3* This Calc is good. But has glitches that don’t get fixed. If you do a calculation and use the equals button to use the answer in another calculation it says illegal character found. It never used to do this. Any updates should be tested first before release. ### 1/5 — Why only landscape on iPad??!!! *2021-08-19, version 3.9.2* It’s ridiculous, why can’t you dictators give us a choice to use landscape or portrait on iPad??!!! It’s so annoying and inconvenient, to have this on landscape all the time!! Please amend this oversight. ### 1/5 — Waste of time *2020-11-11, version 3.9.0* Garbage ### 1/5 — Inaccurate Results *2019-01-24, version 3.6.0* Sorry but you just shoot yourself in the foot with your last reply. You say it is wrong to say 200x25%=50 as that would give 200x50=10000 Yet if we apply in your app 200x25% we get the correct answer of 50. Therefore whilst your in app answer of 200x25%=50 falls in line with other apps, your 200-25%=199.75 does not. Other apps show 200-25%=150 As such I am confused why you use one expression for 'x' but a different one for '-'. ### 1/5 — 效果音强行暂停音乐 *2018-11-20* 用个计算器还不让人听歌了真是第一次见 ### 1/5 — Not worth it *2017-08-12, version 3.3.7* First I see no way to enter parentheses to specify order of calculation. Second, each entry is accompanied by a loud annoying click sound that I see no way to turn off. Too much trouble. Not worth it. DELETED!! ### 1/5 — awful app *2016-09-28, version 3.1.5* app shows an error when multiplying two decimals such as .15*.80, furthermore it brings up ads as a popup sometimes which freezes the app and makes it unusable. terrible app ### 2/5 — Good free app but! *2021-08-19, version 3.9.2* Why does preferences open every time you tap the Equals button? ### 2/5 — Percentages? *2021-08-18, version 3.9.1* Adding, subtracting and dividing percentages of a number do not work ‘on the fly’. So there is little point in having the percentage key. Otherwise this would be my ‘go to’ calculator. ### 2/5 — Landscape mode only? *2020-07-20, version 3.9.0* Big buttons but in Landscape mode only? ## Most praised reviews (10 highest-rated) ### 5/5 — Calculator With It All! *2024-03-27, version 4.1.4* Has it all, plus saves history so if you forget, question or need to refer to previous calculations you don’t have to redo them. ### 5/5 — Belle petite calculatrice *2022-08-06, version 4.0.1* Simple efficace et on peut garder les calculs en historique contrairement à celle inclus dans iOS d’Apple ### 5/5 — Never paid for a calculator app before this *2022-08-02, version 4.0.1* Like the title says, my phone has a stock app calculator so why buy one? Never felt the need until now. This calculator app is brilliant, allowing you to save custom functions and calculations. It saves so much time if you’re always calculating the same things. Also love that it saves your history so if you need to remember what a calculation was, you don’t have to recalculate the whole thing. Amazing! ### 5/5 — Excelente *2022-07-25, version 4.0.1* Justo la calculadora que estaba buscando ### 5/5 — Works well *2020-02-10, version 3.9.0* ***.UPDATE*** 2020-02-10 Five stars to this dev. I had a problem and there was a bug that was probably hard to find but after I emailed them the details, they were very diligent on fixing it and other things. For devs to respond like this and put out such a quality product, I gotta raise it up to 5 stars. I like how I can create a formula, save it and use it. History is easy to get to. Nice CALC. 2020-02-02 Opposite Day - 2020 0202 I tried the app and I do like it. I would like an easy way to edit the function I created. There is a bug, but the dev contacted me and helped me find a work around while he searches for the bug. When I try to touch where I want to edit, it actually jumps to the beginning of a segment so the work around is to use the < and > at the bottom to move the cursor where you want it. I might come back and give this 5 stars because it is a nice app and the dev responded to me quickly. Thank you!!! ### 5/5 — More than a Calculator *2020-02-08, version 3.9.0* Great app and easy to use. Way more than a standard calculator. Easy mortgage calculator and even your own functions! Very easy to use! ### 5/5 — The best calculator app for iPhone and iPad *2019-10-13, version 3.6.0* This is a fantastic, feature-full calculator. I continually look for better calculators but just can’t find them.* This is the absolute best. *The reason I’m still looking is that I don’t particularly like the Apple Watch Xmart calculator. ### 5/5 — The app is simply useful *2019-06-15, version 3.6.0* I got the app for free when they offered it, so I don’t know the price of the app but for I what can tell it’s simplicity makes it extremely useful, for example, it stores your operations on the top so that you can review the numbers if there is any doubt, that’s something that the native calculator doesn’t offer and that is presented in a very simple maner, you are allowed to customize the colors of it as well, although I have to say that when you apply a light color the font should change to a dark color so that you can see better, however, I don’t think that’s something to really drop the rating. You can quickly copy the result, edit the operation at any point, etc. About the more technical stuff I can’t really tell, I don’t use those options frecuently, I only use it as a pocket calculator to make calculations at the store or adding up simple things. I guess to answer if it is worth, it will depend on the price, but there is no doubt this app is way better than the original, I don’t know why Apple keeps doing this retro calculator, it is seriously easy to emprove it and yet we are stuck with it. ### 5/5 — Great app - love it! *2019-02-06, version 3.6.0* Great calculator but the customizable functions section is fantastic! Good call! I did notice “one flaw”. Quality control missed it! My only criticism so far. In the custom functions link, it is labeled, “Custom Funcitons”, not “Custom Functions”. Bummer, now I don’t know what I’ll do with this thing... 😉 ### 5/5 — Noice *2019-01-18, version 3.6.0* Wasn’t using this expecting much, but the whole instant-answer function was great. The customizable colors also allow it to be personalized, which is a nice touch. Would definitely recommend. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
