Give this a try
your current search | eval Apps=replace(Apps,"^\d+\s+","")
your current search | rex field=Apps mode=sed "s/^\d+\s+//g"
<your_search> | rex field=Apps "\d+\s(?<ShortApp>.*)"
should produce a new field called "ShortApp" that contains the string after any number of digits, followed by a space.
Assuming that you mean at search-time, like this:
... | rex field=apps mode=sed "s/^[\d\w]+//"
