does anyone know how to enter a date range for place that I want to visit in coush surfing app?

iOS and iPadOS

Hello everyone, does anyone use a couch surfing app? I have a problem that I am unable to resolve. Let us say that I am looking for hosts in new york. In the app I write new york but I am unable to specify the dates when I want to visit the city. Does anyone know what to do about it? I am using iphone 7 with voice over since I am totally blind and the ios that I am using is 11.4. Once again many thanks for your help.
