Quite a few people I know use camscanner which is an app you can use on your phone to “clean up” flipcharts / wall charts. A PC and Mac equivalent is available and is way more powerful, called Scanscribe. Birgit Smit has put a simple, silent, demo of how it works:

The extensive help file can be found HERE.

THIS pdf provides a thorough overview. If you don’t wish to read it, this video covers some of the key points:

 

 

As does this:

 

 

If you are looking for other phone based options, then for iOS the Post It Plus app is great for working with…… Post Its ;-) Microsoft Office lens is also pretty good.

Thanks to Birgit for chasing down the app. The initial source URLs have not been available for a while and even after extensive searches using WayBack Machine, I was unable to find it!

UPDATE Jan 30th 2020: It seems the new OS for mac Catalina has broken the use of this due to  it stopping the Java 6 Runtime. Bogdanw ,a member of MacRumours, has found a work around:

Create an AppleScript with the following:

set theDMG to choose file with prompt "Please select javaforosx.dmg:" of type {"dmg"}
do shell script "hdiutil mount " & quoted form of POSIX path of theDMG
do shell script "pkgutil --expand /Volumes/Java\\ for\\ macOS\\ 2017-001/JavaForOSX.pkg ~/tmp"
do shell script "hdiutil unmount /Volumes/Java\\ for\\ macOS\\ 2017-001/"
do shell script "sed -i '' 's/return false/return true/g' ~/tmp/Distribution"
do shell script "pkgutil --flatten ~/tmp ~/Desktop/Java.pkg"
do shell script "rm -rf ~/tmp"
display dialog "Modified Java.pkg saved on desktop" buttons {"Ok"} 




Then run it! HERE is his thread to see more discussion on this solution.
