No line for customs

I saw signs for the app in the departure lounge at SFO. I installed the app before taking off and enter my passport information. When the plane landed I notified customs I had returned. I didnt see a line for people who used the app so I asked someone and they opened a line for me. I got to speed ahead of everyone waiting for the kiosks. Now if it could only speed up baggage claim.
