Andy from TotalBodyIQ - a newly looking for support and advice

Hi guys, I am completely new to this but am really passionate about what I am trying to do which is to launch a truly ethical and supportive training app for people... I am genuinely a sole independent app developer who has worked tirelessly for two years to build something I feel has real potential... but I now have so little knowledge about how to actually make it visible to people I am looking for some support from this community... Any support would be greatly appreciated...

Cheers, Andy
