• Programmable, with labels, subroutines, branching, conditionals, indirect addressing, annotated program listing, and memory for 198 program steps
• Library of Sample Programs
• Fast, slow or single step program execution
• Program import via pasteboard or from other Apps
• Program export via printer, email, pasteboard or to others Apps
• iTunes program File Sharing
• Two additional windows with views of:

What’s New

Version 2.4

- New Settings option Persist Program Registers. When enabled:
* On program Export device register values are saved to the program.
* On program Import device registers are restored from the program's saved values.
- New external keyboard action: typing M invokes the multiply function, eliminating a shift.
- Nerd alert: iOS versions >= 14 and macOS versions >= 11 now use the modern PHPicker photo chooser rather than the venerable UIImagePicker.
- Minor bug fixes and improvements.
- Update for iOS 15.3.1, macOS 12.2.1, tvOS 15.3.
