My most frustrating one is trying to find the antilog (base 10) function. You would expect it to be a shift function of the “LOG” button (of which there are 2 off, one on the main screen and one if you swipe left). If you want to find the antilog of a number you need to “Shift and X^n” then enter 10 as the X and the number you want the antilog to as the n. Can we please have a 10^x button on the shift “LOG” button on the next update.🙏 ### 5/5 — Capable and versatile *2025-12-14, version 7.0.3* Love the range of operations and capabilities (like memory). I have the paid version. ### 5/5 — review *2025-11-26, version 7.0.3* This is a great calculator and i really appreciate not moving it to a monthly subscription ### 5/5 — Very good *2025-10-05, version 7.0.3* But it needs a Control Centre button ### 5/5 — Happy customer *2025-06-24, version 7.0.3* Excellent App for your mathematical need. ### 5/5 — Évaluation *2025-06-18* Très satisfait ### 4/5 — A good scientific calculator app for iPad *2025-06-10, version 7.0.3* I use this app regularly in combination with another calculator app and it’s a good one. ### 5/5 — Scientific and Graphing Calulator *2025-05-08, version 7.0* A very capable calculator. Takes time to learn how to use all the features. ### 5/5 — The Best *2025-05-06, version 7.0* I have been using the app for a couple years. It has all you need in any calc. Awesome calculator. ### 5/5 — If you need to use a calculator often, it is near perfect! *2025-05-04, version 7.0* Buy this if you need to use a powerful calculator often. The small price is definitely worth it since it isn’t a subscription and there are many functions and tools. This helped take off so much homework! I just tested it out and the ai help thing is amazing. Edit: One thing tho, it would help if the equation solver had some feature where you enter an equation and the app figures out what you entered and automatically does the calculation for that equation (but there should still be a way to manually select the equation). It would also help if there was a formula chart in the [?] section. ### 5/5 — The Best *2025-03-16, version 6.1* This calculator makes solving equations very easy. It has more functionality than I will ever need or use. ### 4/5 — You know? *2024-11-15, version 6.1* They have Oxygen in here then Jennifer l. LaFlora ### 5/5 — Great calculator *2024-11-04, version 6.1* I have been using this in school, and I will continue to use this in school. This calculator has every function pretty much anyone could ever need and is a great help in my math and engineering classes. 10/10 would recommend ### 5/5 — Bonega! *2024-10-18* Ĝi estas bonega kalkulilo. Tre interesa ĝia rimedo celante ekhavi la serion de Taylor. ### 5/5 — 5 stars, worth every penny *2024-10-09, version 6.1* The best graphing calculator I’ve found for iPhone. Well worth the money. Also supports CAS (here called algebra mode) like a HP Prime, so 2*pi isn’t turned into 6.28.. and pi can be later factored out if possible. ### 5/5 — 5 stars, worth every penny *2024-10-04* The best graphing calculator I’ve found for iPhone. Well worth the money. ## Most critical reviews (10 lowest-rated) ### 1/5 — Upgraded to pro in 2017 *2025-11-28, version 7.0.3* And using it now and it will not let me use the photo feature i paid for. ### 1/5 — Keyboard doesn’t work on MacOS *2025-07-21, version 7.0.3* This is unusable on macOS because not doesn’t accept keyboard inputs ### 1/5 — Pro *2025-03-30, version 6.1* When I upgraded to pro I thought it was all I had to do. Now whenever I click and start using my calculator it interrupts me and asks if I want to open pro. It’s such an inconvenience and this needs to be taken care of. Otherwise I’d love it. I just want to click on the App and start using the calculator. ### 1/5 — Underperformance now *2024-10-11, version 6.1* Ridiculous not worth a penny ### 1/5 — Too complex needs to simplified *2024-05-24, version 6.0.1* First it took me forever and a day to find the % sign. Then when I tried to subtract 20% from 74.50 it just kept doing a straight subtraction ie: 74.30. Needs a better UI Thank You ### 1/5 — Paid for and still asks for more *2024-04-05, version 6.0* I’ve had this about two months - very helpful tool but unfortunately, the photo mode (that I paid for) doesn’t work any longer. This is because (as I previously mentioned, I paid money for it), the photo mode is “a third party service requiring additional fees”. Not at all impressed. ### 1/5 — Not cool.. *2024-01-22, version 5.9.6* I paid for the upgrade but it doesn’t work…still says I don’t have Pro Access. No answer from support as of yet. ### 1/5 — High D here I come *2023-11-30, version 5.9.5* love the calculator, but I bought queries for pictures and they were never given to me. I really have no time to do this work! I will probably be screwed in school tomorrow. ### 1/5 — Commas *2023-09-24, version 5.9.2* Really wish there were commas or spacing. 1,000,000 or 1 000 000 For examples ### 1/5 — Product is great *2023-09-23, version 5.9.2* But when you pop up a “rate this app” when I’m trying to do something time critical, that pisses me off. Enjoy the 1 star. ## Most praised reviews (10 highest-rated) ### 5/5 — Must have *2026-08-09, version 7.1* There is more than you think in this calculate. ### 5/5 — Thanks *2026-06-30, version 7.1* The best calculator in the world ### 5/5 — Full Range *2026-06-26, version 7.1* Worth the cost, especially if you want every possible range of calculators. Scientific, graphing, etc. ### 5/5 — Ótimo *2026-06-16* Uma calculadora bem completa muito boa! ### 5/5 — The BEST calculator EVER! *2026-05-25, version 7.1* 'Nuff said. It's the best. Get it. Period. Five year later, still best. Get it. Now. Ten years later; still the best and getting better. ### 5/5 — Superior Calculator *2026-05-20, version 7.1* Given the security risk with being able to unlock iPhone with default calcualtor, deleted, and researched for a reliable calculator. Best phone calcualtor ever- used it to help spouse through college math course…. Better functionality than a scientific calculator… perfect ### 5/5 — ♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️♾️ *2026-05-01* いままで使った電卓で一番使いやすかったです。ありがとうございます😊 ！！！！！！！！！ ### 5/5 — very useful *2026-04-23, version 7.1* 👍👍👍 ### 5/5 — The best calculator *2026-04-15, version 7.1* This is by far the best calculator. It is totally worth the purchase. Please make a Windows app. ### 5/5 — Great app! *2026-04-02* I’ve been using this app for the last 10 years without any bug. Great job, developers!
