Most landlords are not complete assholes. They want to do what is reasonable to keep their tenants happy. It's much easier to re-sign a happy tenant than to have to turn over an apartment and spend time and money marketing it and possibly have it vacant for a while. If all the tenants hate the laundry app and let the landlord know (politely, with a list of machines that don't work, dates/times, etc), most likely it will have an effect.
