I think the biggest mistake is you pursued a high risk startup relying on the first iteration to go smoothly without having a plan in case things did not go well. It sounds like you're running out of money personally? You need to fix that first. Realize that you've shown you can build an iPhone application and try to leverage that into some work. Or try to get external funding for your idea. I wouldn't give up on Grooovy but make sure you're not in a bad situation if it doesn't take off or it just takes longer than you think to get traction. It usually ends up taking longer than you think. The only feedback I have for the idea itself is be very careful about what people say they want. They may be imagining a different execution, or they may like the idea but will never use it.
