This update from Apple will improve the functionality of this app. No new features are included.

NEW:
- Rafter analysis and design portion of Diagonal function has been redesigned and rebuilt from the ground up.  Now you can input Rise, Run and/or Diagonal values using realistic site measurements, instead of "Theoretical" values.  BuildCalc takes these site dimensions and, with your specified design details, it calculates the rafter layout (including corresponding theoretical dimensions) and generates a complete Rafter Layout Drawing
Fixed:
- Crash when entering advanced functions after a fresh install
- iOS Swipe bar overlaps BuildCalc's Toolbar at page bottom - making some operations very difficult to access.
- Entering HBP (Height Below Plate) incorrectly calculates HAP and breaks Common Rafter layout drawing.

NEW:
- Easier access to [Done] button in Advanced Views
- Press and hold Main Page output value to copy to clipboard

Modified the button labels for the Advanced Function Recall and the Sizes Editor to be more intuitive

FIX : iPhone Home Bar overlaps [0] [.] and [=] keys, making it sometimes difficult to use those buttons or the Home Bar

Fixed:
- Error in listed Stair Stringer Length (value shown on drawing is correct) when using Sub-Risers in design;

Fixed: Email of drawings not working on more recent versions of iOS 13

Fixed:
- Popup keypad not appearing on iOS 11 iPads

Fixed:
- When device is set to Dark Mode, advanced calculation pages are too dark for outdoor use;
- App crashes when Thousands separators are enabled;

Updated for iOS 13.5 compatibility.

Fixed:
- Last riser/tread intersection dimension of Stringer Layout not shown when Flush Landing is ON;
- First riser/tread intersection dimension is left justified which can cause it to be off the drawing page;
- Trying to email advanced function results causes crash;

Fixed:
- Certain sequences of [Length] [Width] [Rise] [Run] button presses that cause the Roofing function to produce incorrect results.
- Layout for iPhone X

New:
- Can export contents of tape

New:
- volume control works if the device is muted or not;
- volume control has an additional level (was 4, now 5 levels)
Fixed:
- volume control does not work on advanced functions
- static background noise can be heard on some devices in some conditions

① BuildCalc no longer stops background music (from other apps) from playing
② Volume button will be orange and show mute symbol when device is muted (thereby overriding BuildCalc's key click volume setting)
③ Volume button is scaled correctly for iPad portrait and landscape orientations

New:
- Four levels of volume control: mute, soft, medium, and high;

Fixed:
- Cumulative memory, [M+], fails to allow entry of unitized values;
- [M+] button appearance now indicates if value(s) are in cumulative memory;

Fixed:
① poor contrast for buttons that indicate a value is saved in memory
② some saved values are lost upon app restart
③ Welcome screen displayed at each launch

New: Keypad memory buttons and labels will be red when a stored value is available.
Fixed: Selecting on second advanced function cell while a first cell is selected causes the first cell to be not selectable

Fixed: able to do (a÷b= +===) repetitive operations.

Fixed:
* failure to use [Slope] values to calculate [Rise], [Run], or [Diag] results;
* failure to calculate advanced function Rise or Run when last two changes are Pitch and Diagonal

Fixed:
◦ [Diag] function fails to allow entry of dimensional lumber values (ex: "2x10", "4x12") for "Rafter WxH" and "Ridge Beam WxH";
◦ [Diag] function returns wrong value for "Ridge Post Height";

Added:
◦ Ridge Post Height to Rafter Layout drawing;

○ Added Rafter Cord Length and Roofing Length to [Diag] function results and drawing;
○ Fixed broken links to "Hip and Valley Angles" articles in [Hip/V] help;

Fixed: Mangled layout on 6 plus, 6s plus and 7 plus screens when launched in landscape orientation; BuildCalc logo missing from PDF drawings;

Fixed:
 ◦ "Fractional Resolution" Fractional Mode Display Formatting is working again.

Fixed:
 ◦ [-][=][=][=], [x][=][=][=], and [÷][=][=][=] are working again;
 ◦ FAQ link and icon in main info screen;
 ◦ "Fractional Resolution" Fractional Mode Display Formatting is working again.
