It took me forever to find it, but I finally did. It’s buried in the settings. Other than that difficulty the app is great. ### 5/5 — Fantastic Calculator! *2017-12-03* Has everything except calculus. Great graphing capabilities, easy to use. Love it. ### 5/5 — Fantastic! *2017-10-12, version 10.2.3* It is clear that a lot of thought and effort went into making this the best calculator app (imo). Really well done, worth more than it costs, so get it! ### 5/5 — Better than Desmos *2017-10-11, version 10.2.3* It’s good ### 5/5 — Helpful! *2017-09-19, version 10.2.3* This app is incredibly helpful and useful ### 5/5 — It's *2017-09-01, version 10.2.2* Good ### 5/5 — Great app *2017-05-26, version 9.3.1* Great calculator! Thanks for the quick fix ### 4/5 — Great app, new update kills battery *2017-04-13, version 9.1* I've been using this app for a while now and it's always done the job super well. Only issue is that the most recent update has caused a huge issue with battery. 29 minutes on screen has killed 20% of my battery. Hopefully this gets fixed! Updating this review for the new update: The history is cleared every time the app is killed. Another annoying little issue I wish didn't exist but otherwise still a great app ### 5/5 — Very happy with old and new version *2017-03-24, version 9.0* Good job! This calculator has been a useful tool. ### 5/5 — Excellent App *2017-03-10, version 9.0* I've used this app for several years and it's by far the best option available on the App Store. Would give more stars if I could. ### 5/5 — There isn't anything better *2017-02-16, version 8.8* What an app! It has a nice, large interface and does every calculation you could possibly need, from simple multiplication to college-level calculus. A calculator like this would normally set you back $5 at least, and a TI calculator would cost $50 used; you'd be hard pressed to find a better bang for your buck. I'm impressed! ### 5/5 — Graphing calculator iOS version *2017-02-02, version 8.7* Picked this app up for review purposes to help my stepson with college calculus. It does pretty much everything my HP 48 did for me back in the early 90s but with touch screen flexibility and at about 1% of the cost. A must have for students, teachers and professionals looking to brush up. 5 stars easily. ### 5/5 — A must have app! *2017-01-31, version 8.5* I love this app. It gets regular updates and is just GREAT for school! This is a great replacement for that huge TI 89 calculator we all remember. Seriously, this app is worth the money. I'm so glad I bought it instead of a way expensive graphing calculator. You'll love it too. ## Most critical reviews (10 lowest-rated) ### 1/5 — Complex miscue *2019-02-01, version 10.4.2* It correctly calculates e^(I x pi) as -1, but says that ln(-1) is undefined ????! ### 1/5 — Promises a lot delivers little *2018-11-25, version 10.4.2* Too bad I can’t get my money back for this app, it can’t graph simple user equations. Whats the point. ### 1/5 — dont trust this app graphCalc 2 *2017-01-25, version 8.6.4* Data for chemical elements are wrong particularly mass weigh elements with unit amu Bogdan ### 1/5 — Does nothing a graphing calculator should. *2016-04-04, version 1.7* It is very primitively designed. ### 2/5 — Good but ....... *2017-11-21, version 10.2.3* Latest upgrade: cannot access references!! ### 2/5 — Graph Calculator *2017-09-06, version 10.2.2* Wish I hadn't purchased it. References don't work or only work once, then you have to close the program and re select a reference... Inputting information is not intuitive..looks like you can select one reference to read, but when you back out of it, you are unable to select another unless you exit the program and restart it. ### 2/5 — Not an accurate graphing calculator *2016-10-25, version 8.3* Wasn't an accurate representation. Didn't have everything I needed ### 2/5 — Freezes *2016-03-23, version 1.6* Every time I click on graph, the app freezes. Every.....time ### 3/5 — Love the app, needs some fixes *2023-05-09, version 10.5* I love this app and have been using it a long time. I used to use the free version but bought the pro mostly to support the developers but I have to use the free version for some things. For example, when I try to use Days Between Dates it immediately crashes the pro version but not the classic version. This app is great but needs some updates ### 3/5 — Please update i really need this app in my life :( *2020-11-24, version 10.5* I’m mostly writing this revoew in hopes that the dev sees. Ive been using this app for years as my graphing calucluator, and its amazing. However since updating my phone it doesnt work, and i can’t even get to setting in order to write the developer directly. I hope this is a bug that gets fixed quickly, and that the deceloper is alright ## Most praised reviews (10 highest-rated) ### 5/5 — Amazing calculator app! *2025-09-22, version 10.5* This is a very impressive calculator, all the more so for being written by a single developer. Tons of features yes, but it’s the internal functionality that really amazes me. Try entering 10^100+1-10^100 and arcsin(arccos(arctan(tan(cos(sin(9)))))) into another calculator or calculator app. Most will get these wrong because of floating point rounding errors. I would love to see how this app actually handles things. It must be some combination of symbolic and numerical calculations. Again, really impressive stuff. ### 5/5 — Great for engineers *2025-05-28, version 10.5* I use this almost every day for work and personal projects and it has everything I could ask for in a calculator! ### 5/5 — The only calculator you'll ever need *2023-06-12, version 10.5* Does so much, very streamlined for the most part. I use it for multi-step calculations regularly and there's nothing quicker. Would like to see base conversion added as a feature. ### 5/5 — The only calculator app you'll ever need *2020-09-08, version 10.5* I've had this calculator for years and I'm still finding out about new things it can do to this day. It's gotten me from algebra through three levels of calculus and made it all so simple. The size of this thing is insane, there's so much to explore and it can store a ridiculous number of graphs/matrices/data sets all at once. It's easy to customize and tune it to any type of math that you're doing at the moment so that your most used functions are always just one touch away. Seriously, just install it and you won't need to download another one ever again. ### 5/5 — Nice Calculator *2019-11-09, version 10.4.2* I am a real user of this app and it is a good one. It puts all of the power of a scientific calculator on your cell phone. Super easy to use: you can see all of your calculations, edit them, and reuse them. Kudos to the developer. Keep up the great work. ### 5/5 — Excellent. *2019-10-23, version 10.4.2* Simple, reliable and versatile. Unvaluable app for Math students. ### 5/5 — Best Graphing Calculator *2019-07-19, version 10.4.2* Input is on a separate tab from the actual graphing so input won’t cloud up the screen, and you can zoom on each axis independently. It can graph implicit and explicit equations (up to 20 explicit!). And it can graph derivatives and integrals for you, so you don’t need to find their analytical form ahead of time. Last, it supports user defined functions. Great!! ### 5/5 — Very good app *2019-03-12, version 10.4.2* Fantastic app . So much info. This app is well done. Help me and my kids a lot. Thank you ### 5/5 — Great! *2018-08-18, version 10.4* The free version is an excellent graphical tool, with an extraordinarily good scientific calculator, the pro version is rather economic and gives subtle but powerful improvements, that provides the app a better performance and makes it a powerful and very intuitive tool. ### 5/5 — Really really good calculator *2018-01-23, version 10.3* I only wish school would let me use it during tests --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
