Hey I've made an app - waiting for Apple approval, so ready some time in the next two weeks, literally released it two days ago on Android. It's called parksports and allows people to create casual games in the parks in your area. Totally free to use, and a few plugs could get the ball rolling for both of us https://play.google.com/store/apps/details?id=io.zapo.parksports
Happy to PM / take this offline if you want to chat further
Hey, I'm actually in a similar position. I'm trying to work out the best strategy of how to get my casual social sports app off the ground (shameless plug https://play.google.com/store/apps/details?id=io.zapo.parksports). Which in a sense is like a sports club - I need to hit a critical mass of people in my local area to get the ball rolling. So my response is more me thinking out loud than anything else.... What I have seen other successful sports clubs do is have a "sign on" day. I think this works well for parents because they need to have something to take their kids to, and it's a great way to grow the club. They advertise this locally by getting corflute signs made and put up around the area. Usually this is done some time in advance ~1 month. The weekend before it wouldn't hurt to setup a little desk advertising the sign up outside a the local grocery stores if they do that in your area. Do you have some other players? Don't do it alone, get them to chip in too. That's all I have for the moment
Edit: sometimes you may need to do it for a few weekends as well if it's a new club
