Compare 2 Apps

We cloned an app from another and further development work has been done on the cloned app.  Is there a way to to a comparison between the 2 apps to see what has changed since cloning?
Hi Colin,

Not between apps but you can compare and merge eSpace modules. Use the option compare with file from the eSpace menu.

For extensions you'll have to compare the c# or java code but for that there are a lot of tools out there...
