How to reset BuildCalc (iOS)

If BuildCalc launches OK but either some of the advanced functions do not work properly or you just want to reset to the factory settings, the following steps are recommended:

From the main keypad, tap:[Conv] [Prefs]
At the top of the “Preferences” screen, you should find the “Reset” cell. Tap either [Imperial] or [Metric] to reset BuildCalc to its factory settings.

However, if BuildCalc fails to launch or is frozen, you may wish to restart it.  You can do it by:

Return to your iOS devices home screen by pressing the home button.
Double tap the home button to show your currently running apps.

Find the BuildCalc icon in the row of currently running apps at the bottom of the screen.  There may be more than 4 apps running, so try swiping your finger from right to left on the botton row to show more running apps until you find BuildCalc.
Once you find the BuildCalc icon among the currently running apps, press and hold it until all of the icons at the bottom of the screen start to jiggle and show a red circle with a white minus sign.

Tap on the red circle with the minus sign for BuildCalc.  This will stop BuildCalc from running.
Tap your screen, above the bottom row, to hide the row of currently running apps.
Restart BuildCalc
If BuildCalc won’t start properly, try these …

iOS5 crash

UPDATE: (10/28/11):  Version 2.1.6 is now available from iTunes.  v2.1.6 addresses all of the issues listed below.  Thank you for your patience during the approval process!

Entering values into the Advanced Function ([Stairs], [CmpMtr], [Balster], [Diag] and [Hip/V]) cause BuildCalc to crash on iOS5 updated devices. The fix has been found and will be submitted to Apple for review ASAP. Updates will be posted as they are available.

UPDATE (8AM EDT, 10/16/11): There are two issues with version 2.1.4

Old iPod touch: buttons missing from top row of buttons
iPhone2G: crash at launch (this may rather be an issue with 3.x versions of iOS).

A solution to the iPod issue has been found.  Currently, I am trying to replicate the iPhone2G issue.
UPDATE (5PM EDT, 10/15/11): Apple comes through! I am guessing that Apple anticipated a rash of issues with apps on iOS5 because their review of BuildCalc version 2.1.4 was in near record time! It is now available as a free update from the App Store. You can find upgrade instructions here.

UPDATE (2PM EDT, 10/13/11): First, my apologies for any trouble iOS5 may be causing you. Now that I have had a chance to get my hands on it, I like what I see but it appears that a lot of apps (including BuildCalc) were not ready for the transition. Because of this, I won’t be updating iOS on my iPhone for a few weeks (until more apps are updated).

As for BuildCalc, a new binary has been submitted to Apple for review. It has …

Won’t launch, crashes, or freezes:

The following is a list of causes and recommendations if you find yourself having problems with BuildCalc.

Most likely (Apple): Your copy of BuildCalc did not download correctly when you purchased or updated it. The remedy is to uninstall and reinstall BuildCalc (preferably via iTunes rather than the App Store App). You can find instructions on how to do this here.
Most likely (Android): BuildCalc’s configuration files have become corrupted. The remedy is to clear BuildCalc’s data. Instructions are here.
If BuildCalc freezes when only using a particular function (but not the other functions), then the function’s configuration file may have been corrupted. There have yet to be any reports of this on Apple devices but this has happened on Android devices. The remedy is to re-instate BuildCalc’s factory settings by (within BuildCalc):


Tap [Conv] [Prefs]
Tap the [Imperial] or [Metric] button (depending one your preference) in the “Reset” cell.
Tap [OK] on the reset notification
Try the problem function again. If it still doesn’t work, try follow these instructions

You may have found a serious bug with BuildCalc. Unfortunately no software of any substance is bug free (and if it were, you’d be too busy dealing with the flying pig problem to notice). But if uninstalling and reinstalling doesn’t work, then please contact me as soon as possible so I can get you up and going right away.

I uninstalled BuildCalc … how do I get it back?

Fortunately, both Apple and Android thought this one through for us.  The only thing you will need to know is the Apple iTunes or Google account you used to initialize your device.  Here are the instructions to get your copy of BuildCalc back.
Android Devices

Launch the Google Play (was Android Market) App and then tap on the search icon.
 
Enter “BuildCalc” into the search box and tap the [Go] button.
Notice the “Purchased” text at the bottom right of the BuildCalc cell. This indicates that Google remembered your purchase and that you can redownload BuildCalc for free! If, instead, you see BuildCalc’s price and you are sure you purchased BuildCalc then most likely you are not logged into the same Google account you were when you purchased BuildCalc. Be sure that this Android device is associated with that Google account. In other words, is the email account on this device the same as it was when you purchased BuildCalc?
Tap on the BuildCalc cell (as shown in the above screen shot) and then tap on the [Install] button in the BuildCalc product page.
Tap the [Accept & download] …

iPad: the [Done] button is missing!

If you are running BuildCalc on an iPad and the [Done] button is missing on the “enhanced” and/or the “advanced” function screens, here is what is going on: Older versions of Apple iOS have a bug that prevents screens like this from being displayed correctly WHEN the screen is locked in landscape orientation. Usually, one would lock the screen in landscape orientation for a reason, so I’m not going to tell you the fix is “unlock the screen orientation”. Rather, the easiest fix is to update to the most recent version of iOS. The next time you go to sync your iPad with iTunes, iTunes should automatically ask you if you want to do this.

Is there a way to make BuildCalc easier to see in direct sunlight?

I’ve had this problem too.  When you’re in the field, all of these smart phone devices are hard to see.   Tablets are worse!  Getting an iPad pushed me over the edge on this one.  As of version 2.1 (now available on Android and should be on iOS next week), you can switch the display to “Daylight Display Mode” by (1) pressing and holding the ⓘ symbol (in the top left corner) and then tapping on the [+] key.  BuildCalc will go from a display as shown on the left to that on the right … which looks great in full sun.

    

Repeat the above steps to turn off “Daylight Display Mode”.  Also, you can switch “Daylight Display Mode” by going to BuildCalc’s preferences via [Conv] [Prefs].
