I lived on a 41cx through college and this is a great replica. -- Digitalfix, 2013-12-09 ### *---- "Broken" I just installed this app and was not able to enter any values, and the app was completely unresponsive and nonfunctional. -- Fastfingers0007, 2012-11-30 ### ****- "HP 41CX" Great app! Can the calculator go landscape of portrait? thanks -- efangue, 2012-11-10 ### ***-- "Good first attemp" I am all for lower cost software and the developers are to be applauded for releasing this reasonable emulation of the 41CX at a very reasonable price. And this release is quite useful if you want to see if you "like" having a 41CX on your iPhone. Unfortunately if you are serious about using all of the functionality of the 41CX, the current release of this app fails. At least in my configuration (iPhone 4/iOS 4.3.5) some functions do not execute. E.g., Beep, Tone n, Clock., XYZALM. And Seekpta causes some major memory shifts resulting in a loss of calculator programmed functions. I have alerted the developers and hopefully they will address these deficiencies. -- Let's Be Objective, 2011-10-12 [View all Crimson Calculator 41cx reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to Crimson Calculator 41cx - [Bayes' Theorem Calculator](https://apptail.io/app/bayes-theorem-calculator-ehlb/united-states) - [Mathematics with PocketCAS Pro](https://apptail.io/app/mathematics-with-pocketcas-pro-PVfc/united-states) - [Physik++](https://apptail.io/app/physik-NqRc/united-states) - [Option Show - risk calculator](https://apptail.io/app/option-show-risk-calculator-NVRc/united-states) - [iAltair](https://apptail.io/app/ialtair-bqoe/united-states) - [NOMA Mobile Guide](https://apptail.io/app/noma-mobile-guide-tAti/united-states) - [Art of Stat: Resampling](https://apptail.io/app/art-of-stat-resampling-kVxm/united-states) - [Math Solver Pro](https://apptail.io/app/math-solver-pro-gHQn/united-states) - [CloudLabs Electronic Organette](https://apptail.io/app/cloudlabs-electronic-organette-ZcFp/united-states) ## Crimson Calculator 41cx Available In - [United States](https://apptail.io/app/crimson-calculator-41cx-YGBe/united-states) - [Mexico](https://apptail.io/app/crimson-calculator-41cx-YGBe/mexico) - [Norway](https://apptail.io/app/crimson-calculator-41cx-YGBe/norway) - [Canada](https://apptail.io/app/crimson-calculator-41cx-YGBe/canada) - [Belarus](https://apptail.io/app/crimson-calculator-41cx-YGBe/belarus) - [Switzerland](https://apptail.io/app/crimson-calculator-41cx-YGBe/switzerland) - [Chile](https://apptail.io/app/crimson-calculator-41cx-YGBe/chile) - [China](https://apptail.io/app/crimson-calculator-41cx-YGBe/china) - [Colombia](https://apptail.io/app/crimson-calculator-41cx-YGBe/colombia) - [Dominican Republic](https://apptail.io/app/crimson-calculator-41cx-YGBe/dominican-republic) - [Algeria](https://apptail.io/app/crimson-calculator-41cx-YGBe/algeria) - [Ecuador](https://apptail.io/app/crimson-calculator-41cx-YGBe/ecuador) - [Egypt](https://apptail.io/app/crimson-calculator-41cx-YGBe/egypt) - [United Kingdom](https://apptail.io/app/crimson-calculator-41cx-YGBe/united-kingdom) - [Hong Kong SAR China](https://apptail.io/app/crimson-calculator-41cx-YGBe/hong-kong) - [Indonesia](https://apptail.io/app/crimson-calculator-41cx-YGBe/indonesia) - [Israel](https://apptail.io/app/crimson-calculator-41cx-YGBe/israel) - [India](https://apptail.io/app/crimson-calculator-41cx-YGBe/india) - [Iceland](https://apptail.io/app/crimson-calculator-41cx-YGBe/iceland) - [Japan](https://apptail.io/app/crimson-calculator-41cx-YGBe/japan) - [South Korea](https://apptail.io/app/crimson-calculator-41cx-YGBe/south-korea) - [Kuwait](https://apptail.io/app/crimson-calculator-41cx-YGBe/kuwait) - [Kazakhstan](https://apptail.io/app/crimson-calculator-41cx-YGBe/kazakhstan) - [Lebanon](https://apptail.io/app/crimson-calculator-41cx-YGBe/lebanon) - [Madagascar](https://apptail.io/app/crimson-calculator-41cx-YGBe/madagascar) - [Malaysia](https://apptail.io/app/crimson-calculator-41cx-YGBe/malaysia) - [Nigeria](https://apptail.io/app/crimson-calculator-41cx-YGBe/nigeria) - [New Zealand](https://apptail.io/app/crimson-calculator-41cx-YGBe/new-zealand) - [Peru](https://apptail.io/app/crimson-calculator-41cx-YGBe/peru) - [Philippines](https://apptail.io/app/crimson-calculator-41cx-YGBe/philippines) - [Pakistan](https://apptail.io/app/crimson-calculator-41cx-YGBe/pakistan) - [Russia](https://apptail.io/app/crimson-calculator-41cx-YGBe/russia) - [Saudi Arabia](https://apptail.io/app/crimson-calculator-41cx-YGBe/saudi-arabia) - [Singapore](https://apptail.io/app/crimson-calculator-41cx-YGBe/singapore) - [Thailand](https://apptail.io/app/crimson-calculator-41cx-YGBe/thailand) - [Türkiye](https://apptail.io/app/crimson-calculator-41cx-YGBe/turkey) - [Taiwan](https://apptail.io/app/crimson-calculator-41cx-YGBe/taiwan) - [Ukraine](https://apptail.io/app/crimson-calculator-41cx-YGBe/ukraine) - [Vietnam](https://apptail.io/app/crimson-calculator-41cx-YGBe/vietnam) - [United Arab Emirates](https://apptail.io/app/crimson-calculator-41cx-YGBe/united-arab-emirates) - [South Africa](https://apptail.io/app/crimson-calculator-41cx-YGBe/south-africa) - [Argentina](https://apptail.io/app/crimson-calculator-41cx-YGBe/argentina) - [Australia](https://apptail.io/app/crimson-calculator-41cx-YGBe/australia) - [Brazil](https://apptail.io/app/crimson-calculator-41cx-YGBe/brazil) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
