Supposedly it detects when you arrive at the store, notifies you & lets you send a message to the online pick up staff to pull your order so you dont have to stand in line.
I could see that the order was ready by going thru the menu, but never got the promised notifications and had to wait in line.
Another customer- also in line said he had been in earlier in the week, picked up his order, THEN the app notified him when he was almost to his car.
This app is worthless!
