Hello
I've just released a novel ballroom dancing app and while I love the software side I'm not so keen on the marketing and social media side. The early app sales percentages look OK so it just needs numbers now. Again I know I can buy downloads but the whole thing is just a nice little project that I'm sure would better if someone with a bit of experience took this on with the motivation of making more money from more results.
Is this common or possible and any recommendations, please.
You can see details of the app at phonedancing(dot)com
Thanks
