Only if you want the script to be alive for a finite time.  If the need
is for the app to start gracefully on system startup and stop gracefully
on system shutdown, then 'at' should definitely not be used.  If it
should run for oh, say, the first 17 hours after powerup, then yes the
at command should be used.
