*** AVAILABLE FOR A LIMITED TIME, DON'T MISS OUT! ***

i41 is based on the highly rated i41CX+ but with its keyboard pre-configured to meet the needs of casual and moderate RPN scientific calculations and based on the beautiful and modern Bauhaus skin created by Lewis M. Dickens III, Architect. i41 is a showcase of the power and flexibility of its fully featured parent, i41CX+. Even without the advanced features of i41CX+, i41 is a powerful RPN calculator for the iPhone and iPod touch that will meet many users' calculation needs in a comfortable portrait form factor.

FEATURES:
• RPN logic with 4 element stack
• Arithmetic, trigonometric, mathematical, time, and statistical functions
• 52 main memory registers for temporary storage of data
• Statistical functions (MEAN, SDEV)
• Time functions (HMS, HR, HMS+, HMS-)
• 12 character display
• Copy and paste support
• Option to hide mini stack (X, Y, Z, LastX) display and use the iPhone/iPod touch status bar instead
• Automatic decimal and thousands delimiter separator style
• User adjustable feedback sounds volume
• Extremely responsive and animated key clicks with optional glow feedback effect
• Beautiful and clean user interface optimized for the iPhone and iPod touch portrait mode screen aspect ratio and to maximize the keypad area while still providing for a full featured scientific keypad

NOTE: Because i41 does not have a persistent state, the FIX/SCI/ENG setting is set to 4 decimal places every time the application is launched. Data registers are also cleared every launch. If persistent state is important to you, please consider getting i41CX+ instead.
