Description
i41CX+ is an advanced programmable and expandable RPN scientific calculator with a virtual thermal printer/plotter and workstation-class CAS capabilities that is far beyond a mere replica of the original. In addition to being functionally equivalent to the world-renowned HP-41CX and providing access to its entire library of modules and programs, i41CX+ is enhanced with iOS and hardware features, keyboard overlays, rich set of import and export capabilities, traditional and upbeat diverse set of skins, complete color control, iCloud support, and much more.
The i41CX+ CAS is a full implementation of REDUCE. It's like having Mathematica or the computational engine of Wolfram Alpha in your pocket and, best of all, it runs natively so no internet connection is required. The CAS is fully programmable and provides the ability to reuse previous results in computations. Moreover, the CAS has full access to the calculator registers so it is possible to combine RPN programs with CAS programs.
This is the finest and most powerful scientific/engineering/financial calculator for iOS devices bar none.
CALCULATOR FEATURES:
• RPN logic with a 4 element deep memory stack
• 319 main and 600 extended memory registers
• Over 400 built-in functions, including over 100 functions created specifically for i41CX+
• Time, calendar, alarm, and stopwatch functions
• Four module ports provide access to HP-41 expansion pacs
• Rich set of functions and algorithms: numerical, mathematical, statistical, complex, matrix, numerical integration, curve fitting, solutions to equations, and much more
• Powerful, flexible, and programmable Computer Algebra System (CAS) supporting symbolic, arbitrary precision, scalar, vector and matrix algebra calculations, 2D/3D plotting, and much more
• Full-screen text editor with configurable font style and size, color scheme, a user configurable macro keyboard, and a numerical keyboard
• Access to the entire HP-41 library of solutions for science, mathematics, statistics, engineering, business, financial, surveying, medicine, real estate, and many other domains
• Programmable - virtually unlimited number of lines
• User definable keyboard
• Ability to operate the calculator using a Bluetooth keyboard
• Device integration: external display mirroring, copy and paste, in-app mail, system keyboard, GPS, accelerometer, digital compass, time and date synchronization, AirPrint, and much more
• Virtually unlimited data and program storage capacity using the device's flash memory for local storage
• Import/export data, programs, overlays, modules, etc. via the web, email, and iTunes file sharing
• iCloud syncing of files and preference settings
• iOS 8 Notification Center widget
• 43 available keyboard overlays and support for user created overlays
• Sound support including synthetic tones and interface sounds
• Support for calculator skins and optional mini stack display
• Adjustable calculator speed, sound volume, and display colors
• Usage & Examples table with usage tips and examples
• Quick Reference Guide of all built-in functions
• CAS Quick Reference with all built-in functions, operators, switches, and packages
• Beautiful and clean user interface
PRINTER FEATURES:
• Support for printing, plotting, graphics, and special characters
• User configurable and programmable print color
• Export printer output via email, clipboard, or AirPrint
• Ability to save a JPEG image of the paper roll to the device's photo album

Ich benutze die App jeden Tag mehrmals …
… und finde sie jeden Tag super! Das Original hab ich auch noch, aber das liegt im Schrank.
Please also provide it for M1 Mac.

Very cool! I love this app! The best on iphone!
Hab meine alten deutschen Handbücher wieder aus dem Keller geholt, damit ich die Handhabung wieder wie im Studium '83-'86 drauf hab. Gott sei Dank muss ich keine Nullstellen mehr bestimmen. Aber das erste Programm läuft schon wieder. Thank you Antonio Lagana‼️‼️‼️‼️
Lässt sich auf iPhone 7 Plus nicht mehr öffnen!!!
Seit gestrigen Update geht die App nicht mehr!!!
Auf dem iPad pro nicht mehr nutzbar
Warum kann man von einer sehr guten App nicht einfach die Finger weg lassen? Seit gestrigem Update ist der Rechner auf dem iPad pro (2. Gen.) nicht mehr nutzbar. Nicht nur passt das Layout nicht mehr - das wäre ja noch zu verschmerzen - er reagiert auch nicht mehr plausibel auf Tastatureingaben. Somit leider nicht mehr zu gebrauchen. Auf dem iPhone 11 gibt es keine Probleme. Update: Einen (!) Tag später kommt ein weiteres Update, und nun ist wieder alles in Ordnung. Vielen Dank für den schnellen Fix!!
Einfach Klasse
Mein HP41-X ist wie diese App, oder umgekehrt: 100% wie mein Taschenrechner! Umsetzung 1:1. Besser geht nicht.
Launch time with 7.5.0...
... is really amazing! Thank you so much!
Das Original!
Ein HP 41CX hat mich durch das Studium begleitet und ich habe den Kauf nie bereut. Umso mehr hat es mich gefreut, als ich vor Jahren den i41CX+ für iOS entdeckt habe. Der Entwickler hat ganze Arbeit geleistet. Der i41CX+ bildet nicht die Funktionen des originalen Taschenrechners nach, sondern er emuliert die Hardware, so daß die Originalsoftware des HP 41CX (die Original ROMs) in der Emulation laufen. Näher am Original kann sich ein Programm nicht verhalten. Ich bin dem Programmierer sehr dankbar für seine Arbeit und benutze den i41Cx+ wann immer ich etwas berechnen muß.
Test bestanden!
Ich arbeite jetzt 40 Jahre mit HP-Rechnern und habe viele recht umfangreiche Programme geschrieben. Diese App ist von absoluten Profis geschrieben worden. Super Support! Meine Programme habe von "Hand" eingegeben um einiges zu testen. Besonders angenehm ist der Ex- und Import der großen Programme. Hier wurden mir Tipps gegeben, die mir sehr halfen. Mit dem schnellen Import der Programme ist das Handling super. Ich benötige keine Kassetten, keinen zusätzlichen Drucker; der Ausdruck geht per E-Mail, oder in eine Textdatei. Es ist für mich mit großem Abstand die beste App, die man erwerben kann. Dickes Lob!!!
