Affiliate Marketing Secrets

Hello, I want to make a dating app for a specific niche and I wanted to know if there are sites that offer samples like they do for websites, such as scripts & templates. I want to know if there is something like this for phones an app sample where you can add your own logo & branding and launch ur own dating app

I guess what I am saying is, what is your opinion on niche dating websites like this one.

There are several dating websites for Christians and people of the Jewish religion. Are there any dating websites for the Armish or other such obscure niches?
