Stonebridge Car Wash appreciates all the excitement about the car wash app and we are glad to have this addition to our car wash services. Many customers have wondered about how to add additional people to the plan. As of right now, the app supports one person/one phone per plan. We are working on a family plan that will allow you to add additional members to your app. We will get that to you as soon as the app developer is able to complete the addition to the plan. We have no estimated timeline for completion at present.
