I cannot recommend this app highly enough. ### 5/5 — Super Application.. *2015-01-21, version 2.2.1* Best of the scientific and ordinary calculator apps. Excellent screen layout, all the required functions. A very good values... don't waste your time with anything else, you'll be happy with Calculator XL-Std, Sci, & Unit Converter!!! ### 5/5 — 99 *2014-09-08, version 2.2.1* Best .99 cents I have ever spent. Use this all the time. I have sold at least 10 of these thru word of mouth. We ### 5/5 — Very Handy *2013-09-02, version 2.1* For quick conversions its great. Use it often. Worth the purchase. ### 5/5 — Cool calculator *2013-08-16, version 2.1* Awesome calculator for iPad ### 5/5 — Love the functions and history list *2013-08-12, version 2.1* I've been using this calculator for over a year and I love it. It has all the functions I need, simple number pad that can easily be switched, and I love the history list. ### 5/5 — AAAAAA+++++ *2013-07-29, version 2.1* J'adore ### 4/5 — Flaws *2013-05-24, version 1.9* Great app but the mm to feet and the mm to yard conversion is a decimal point off. 1829mm is not 60 feet. Please fix ASAP. Quite inconvenient. ### 5/5 — I like the large format *2013-05-23, version 1.9* I love this app. The only calculator with a large full page format. Great and fast at typing numbers. Two thumbs up.. :) ### 5/5 — Nice App! *2013-03-22, version 1.8* Smart design ### 4/5 — Nice... *2013-02-22, version 1.8* Especially like the quick conversions. ## Most critical reviews (10 lowest-rated) ### 1/5 — History *2024-05-17* Watch out this update will eliminate all your history on your app. All your calculations will be gone. ### 1/5 — Was great *2024-01-27* This has been my go-to calculator app since I first got an iPhone/iPad 10 years ago. Unfortunately, it now crashes upon launching. Not sure if this is due to a recent version of the app, or my update to iOS 17.3. If this crash gets fixed, 5-stars again … I love this calculator and its different capabilities. ### 1/5 — Will not open after yesterdays update *2024-01-26, version 3.0* Please fix this - I have loved this app for a very long time - after updating it will not open. I have tried uninstalling/reinstalling, nothing works. ### 1/5 — V3.0 won’t run on my iPhone XS Max *2024-01-25, version 3.0* Did the update, now calculator won’t work. Running IOS 17.3 ### 1/5 — Some Calculations Not Accurate *2016-08-03* If you calculate 11^6 using the Y to the power of x function, the wrong answer is given. Similarly, if you calculate backwards, the 6th root of 1,771,561 using the x'th root of Y function, the wrong answer is given. There are other examples. The above are stated as a proof. ### 1/5 — Ne pas acheter !... *2015-08-04, version 2.2.1* Aucun changement avec la version gratuite !!!... C'est une fraude !!!... ### 2/5 — Can’t use split screen on iPad *2017-10-16, version 2.3* This may be a nice calculator but Can’t use it in split screen on my iPad Pro so it is pretty much useless to me. What is the use of an iPad app that can’t be used in split screen? How do I get a refund? ### 2/5 — EE button does not work *2012-03-19, version 1.5* No app support - yet. Scientific Calculator is very limited without that key. ### 3/5 — fix the buttons *2023-11-10, version 2.3* since the last ios update when you turn the phone sideways to see the conversion calc and then go back to the standard calc in the vertical position the numbers on the buttons are not displayed properly. only half are seen. when you press on any of them they go back to normal. please fix this. i love this app but this is annoying ### 3/5 — No Split Screen Function *2019-02-01, version 2.3* I love the calculator itself but I specifically need it to have a split-screen function and it does not yet. I hope this is in this app’s future. ## Most praised reviews (10 highest-rated) ### 5/5 — An app I use every day *2026-03-12, version 4.3* It’s been a reliable go to app since I got an iPhone. I couldn’t live without it. Thank you! ### 5/5 — 3D Chess Game *2025-06-30, version 4.3* Please give us the option to lock the board from moving around , thanks. ### 5/5 — Was great *2024-01-30, version 3.3* This has been my go-to calculator app since I first got an iPhone/iPad 10 years ago. Unfortunately, it now crashes upon launching. Not sure if this is due to a recent version of the app, or my update to iOS 17.3. If this crash gets fixed, 5-stars again … I love this calculator and its different capabilities. REVISED (1/30/2024) The best calculator app is working again! Returns to 5-stars. ### 5/5 — Still My Favorite Calculator *2024-01-28, version 3.0* I downloaded the old version 5 years ago and recently downloaded the XL version. I unlocked the pro sections and still my favorite calculator. ### 5/5 — Fixing my review from 1* to 5* *2024-01-26, version 3.0* Yesterday, after the “graphics update” app kept crashing. I was upset. I tried to start from the App Store link, nope…tried to reboot my iPad, nope. THEN… I THOUGHT… uninstall & reinstall. BINGO! ALL’S WELL! Love this app…wish there was an Android & Windows versions too!! Then I’d be covered 😊 ### 5/5 — Needs Skins *2019-04-14, version 2.3* I like everything except the buttons. The graduated color on the buttons that simulate a curve I find a little distracting. Not a negative on function, just my preference to look. Also, the US Unit/Imperial function in the convert mode is confusing. ### 5/5 — Best Calculator App for iPad *2017-10-21, version 2.3* I've used a few different calculators for iPad, and this one is by far the best! Simple and straightforward. ### 5/5 — Very good , *2017-10-17, version 2.2.1* Nice and easy to use ! ### 5/5 — Full Calculator; no adds *2017-10-05, version 2.3* Everything I need in a calculator with no advertisements. Love it, and fully recommend it. ### 5/5 — Just Right *2017-08-19, version 2.3* This calculator is just right - no adds - simple, scientific, tip, loan available in portrait or landscape modes. Just what I was looking for on my iPad. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
