When packaging an app in App Designer, I always get three output folders:
The appplication found in for_redistribution must be installed before use.
The application found in for_testing can be run immediately without the need for installation (also on a pc without Matlab).
The second options seems more practical, because when updating the application in a shared folder regularly, then the users don't need to reinstall it. So I wonder, what is the difference between those two applications, as they both seem to be working perfectly fine, with the sole difference being the need for installation (or not).
