INTUITIVE TOUCH INTERFACE

Take full advantage of your device's capabilities:

• Overlays - rather than making buttons smaller to fit more, Codex Calc uses intuitive overlays on the existing buttons.

• Popup Menus - hidden until you need them, pop-up context menus give you more power when the default action isn't quite what you need.

• Zoomable History Tape - Tap the history tape to expand for more detail, change the font size, copy contents to clipboard, or forward as an email. View as single-lines to save space, or use multi-line view for more detail.

• Multiple Flexible Layouts - Portrait and landscape, large and small buttons, and seven different graphical themes.

• Easy-Touch Everything - Codex Calc's entire design approach revolves around "touch to activate." Tap the tape to see it bigger, swipe to scroll, long-press a button for more options, tap the display to copy or paste, etc.
