What's New

Added full support for iOS 11, including drag and drop support, and even a (silly) bonus AR calculator mode in the About screen in the Help.†
Support for the iPhone X.
Completely rewrote the display code. Many exciting things to come later which are now possible because of this, but some changes today!
You can now adjust the size of the digits in the display, and make them much bigger or smaller.
You can now use a space for the thousands separator.
Fixed a problem with the normal layout being reset if you opened the app in splitscreen.
Added an edit cursor option to the Accessibility section.
Added a few more alternate icons, for old times' sake.
There might be a small game in the About screen too.†

With the "Engineer Pack" or "Programmer Pack" installed:
Hex, octal, and binary numbers are now grouped using spaces on the display.
Added a arbitrary base "Log N" button to most of the advanced layouts, and you can edit other layouts to add one.

With the "Multi Line Pack" installed:
You can now have lines displayed in two columns on a horizontal iPhone or iPad.

With the "Theme Pack" installed:
Added a variety of new digit styles.

With the "Power User Pack" installed:
Added an option to use haptic feedback for buttons in the "Key Click" section of the settings.
Fixed a display problem with the tape and the "Show implied parentheses" option.

With the "Conversion Pack" installed:
You can now edit and reorder the list of favorite currencies.
Fixed a crash if you pressed on a conversion, function, or constant category name while editing.

† The fancy 3D/AR About screen needs a recent device that supports Metal, ideally an iPad Pro or an iPhone 7/7+ or later. The 3D stuff requires iOS 10, AR support requires iOS 11. You also need to have tipped or made at least one in-app purchase. Sorry school kids everywhere using the free version!
