22-Jan-2018 SawlogCalc v 3.2.4 release

  1. Fixed a bug that could lose all tallies if Android threw an exception while saving data. App will now retain the tallies it had on start up if it can't save when shutting down.
  2. Fixed a bug where entering 1 <sp> 4 <in> would be rejected because of unit inches at end
  3. Fixed a bug where deleting a custom species in the middle of the list would not update a custom species showing in the calculator species button
  4. Fixed a bug for 3-pane displays that would confuse the log-edit page if a new tally was created while editing a log

22-June-2017 SawlogCalc v 3.2.3 release

  1. Fixed a bug in export (Pro version) that put total tally cost in all log lines (instead of individual log cost)
  2. Fixed a bug where changing the name of a tally to blank or to something starting with a digit would mangle the tally date
  3. Changed the note in the calculator pane to clear itself once the sawlog is added to a tally

10-Apr-2017 SawlogCalc v 3.2.2 release

  1. Fixed a compatibility issue that caused KitKat or older versions of Android to crash on any button press
  2. When moving a log from one tally to another, added text to show 'locked' for any locked tallies

02-Apr-2017 SawlogCalc v 3.2.1 release

  1. Fixed a bug which showed incorrect info at the bottom of the tally list if more than six tallies were entered
  2. Fixed display of log cost so that it always fits within the display, even for large values
  3. Reworked help to be a little less confusing


29-Mar-2017 SawlogCalc v 3.2.0 release

  1. Added action bar
  2. Added price per board foot and total price per log
  3. Added the option to enter a note for a log
  4. A new tally will display the date it was created, in tally headers and exports
  5. Changed screens, buttons and list items to be self-sizing. Any screen layout should work on any device (though it may be too small to read or large enough to see across the room)
  6. Added new screen layout: portrait orientation has one pane, landscape has two
  7. Fixed a bug where touching weight or yield on some layouts would be taken as an input and yield strange results
  8. Fixed CSV export to strip the commas out of species names
  9. Fixed export to not try to put in a blank address, subject, CC or BCC (which causes some email apps to complain)
  10. Changed custom species list to remove blank lines in middle of list


1-Mar-2016 Android BoardCalc v3.0.14 release. Fixed:

  1. locked memory register 0 still allowed M+ and MC
  2. with 0 in first memory register, hit 1 + (long press a register and recall value). Failed
  3. a math operation or memory add could result in an overrun which would not be saved correctly
  4. improve sizing of text when scrolling a very large value
  5. recent history will display fractions more evenly and aesthetically
  6. fonts in recent history will now scale correctly to different devices (20 will be the same size on all)
  7. portrait version of Tab5 display size will fill screen on any size device now
  8. button text fixed to scale correctly on all size screens on all devices
  9. M+ will now put result in recent history (instead of starting value)
  10. no longer support Android version 2.1

10-Feb-2014  Android SawlogCalc v3.1.0 released. The table version of the Scribner Decimal C log rule has been added (formerly only had the formula version). A new custom species list has been added where you can enter your own species names and densities. Fixed an odd bug that lost the value of the log serial number if SawlogCalc was started up with two or more tallies saved. Changed layout so that a 7" tablet comes up with three panes rather than two in screen size "auto".

17-Dec-2013 The Palm and Windows versions of BoardCalc are no longer for sale. There just isn't much interest in these any more. They will continue to be available to anyone who has already purchased them, of course, and the web pages for them will remain to make downloads available.

3-Dec-2013  Android BoardCalc v3.0.13 released. Fixed layout for tablets to display correctly in portrait orientation for 7" tablets. Fixed fractions to display symmetrically above and below fraction bar on all devices. Fixed a problem with screen size Small in landscape orientation where a long press on any of the right five memory registers would cause a force close. Rounding a fraction or changing the number of decimal places displayed will now go into recent history. Results in recent history also now show rounding. Added font size 22 (new largest font) to recent history and help. Fixed settings: recent history font size so that changing the font size of recent history from settings would kick in immediately when the recent history pane is showing.


25-Jan-2013  Android SawlogCalc v3.0.2 released. Fixed screen table entries to fix 5" displays. Portrait and Landscape were reversed, rendering both unusable. Added 'undelete' to the Tally List screen. Any deleted tally can be recovered for the next hour of app run time. Log serial numbers have been changed: a new number higher than all others will only be generated when a new tally is created (it used to happen every time the sawlog page was brought up). Fixed text display in buttons of sawlog on small screens, no longer mangled.

19-Dec-2012  Android BoardCalc v3.0.11 released. Changed the calculator display to reduce the size of text if a result is too long to fit in the display. Text size while entering parts of a calculation will still be full size and can run off the left side of the screen, but the result after pressing '=' will always be completely visible.

1-Dec-2012  Android BoardCalc v3.0.10 released. Layouts on single screens changed to fill all available space. Title bar now shows up on all but smallest devices. Monthly licensing checks removed from paid version.

20-Nov-2012  Android Sawlog Calc v3.0.1 released to Google Play, in free and paid versions. Details at Android Sawlog Calc

3-June-2012  Android Boardcalc v3.0.9 released. Added an option to choose what a whole number with no fraction or decimal point is taken as: fraction or decimal. Fixed a bug where entering a number with a decimal point and nothing following would result in a display overflow. Extended the table of prime numbers used to reduce fractions up to 127, so that metric fractions would reduce all the way properly.

10-Apr-2012  Android BoardCalc v3.0.8 released. This version adds a screen size for 5" tablets, and fixes two bugs: rounding of fractions not working after changing Audible or Screen size settings, and scrolling finger off of lowest half of lowest memory register into blank space causing Force Close.

21-Mar-2013  An Android® version of the Calculator was released to Google Play. It supports Android 2.1 and above, on any device with a touch screen 2.8" or larger (including tablets). This is an updated version of the general-purpose calculator from the Palm/Windows suite. The log weight calculator is under construction, release in summer of 2012. More:  Android BoardCalc

  2. Any device set to size Small and used in landscape orientation, on the memory register page, will force close if a long press is done on any of the five upper memory registers, those on the right side of the screen. Fixed in v3.0.13.

Known Issues in BoardCalc version 3.0.8 (Android)

  1. Entering any value that has a decimal point with nothing after will result in an overflow. For example, 2.= results in an overflow. Fixed in v3.0.9

Known Issues in BoardCalc version 3.0.7 (Android)

  1. After changing the setting of "Audible" or "Screen size", rounding of a fraction will only flip between 1/64th and none, skipping 1/32nd, 1/16th, etc. Rotating the screen will clear this. Fixed in v3.0.8.
  2. On a non-tablet, memory register page, if there is extra space below register 9, touch the bottom half of register 9 and scroll finger down off of register. Causes a Force Close. Fixed in v3.0.8
