App customer (4)

Ross

I believe the answer is:

user

'app customer' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for user that I've seen before include "Exploiter (of others)" , "Operator; drug addict" , "Druggie" , "Maybe one needing pot" , "One operating something" .)

I've seen this clue in the New York Times and the USA Today.
