>Do they have a place to mail your complaints? Who forces you to use the app?
Presumably the building he lives in contracted out laundry service to some third party company, which is in charge of the machines and therefore shitty app. In this situation there really isn't any real choice to vote with your wallet. They can tell you to pound sand and there's nothing you can do. Your only real option is to move out. Maybe if OP is lucky, owns the property, and is part of the HOA he might be able to lobby for the vendor to be replaced.
