MATTR Dating App

Has anyone been on MATTR dating app. I have been on it a few weeks. Messaged 2 people but bo reply. I like it as they only send you matches with people of similar interests.  

I just wonder how many people are on it & whether if it is a limited pool, a match is unlikely , especially as I am v specific. 

I want to find a man late 40s or early 50s who likes musicals,  cats & is a Christian. So I guess I just wait,  I sm not in a rush. 

Just wanted to see if others knew about it. It's the only dating app just for neurodiverse folk. The founder answers emails the same day which really impressed me!
