Can someone help find an on-demand web app.

Hi, I am looking for an on-demand web app from example fiverr but for construction, workers, cleaners etc, it should also have android & ios apps. If know a script that comes with an app or a wordpress template anything will work. I did find one but I want to have more options TruelySell - On demand Service Marketplace, Nearby Service Booking Software (Web + Android + iOS)
