Pricing does depend on the app itself. In general, since a lot of people are interested in mhealth, I would encourage you to think of a freemium option that would work well. For pricing our apps, freemium has always been more lucrative than a paid app. I have a theory that most people want to try software before paying for it. For blogs, I would encourage you to embargo publishing information till you are live in the app store (bug free). Keep in mind, that there may be delays in testing and app store review. Happy to talk more if you need specific advice. Cheers, Aditya

You want to think about it from your user's perspective: what level of product development do your potential backers need to see to trust you and believe in your product? That's the minimum level of development you'll need prior to you starting a crowd-funding campaign. Yes people can steal your idea, however there are lots of people selling snake oil out there (falsely advertised products)... If you haven't built a demo or prototyped or what you claim can't be accomplished easily... then the internet will smell that it's a scam, and you'll loose trust with the potential users. Thus, in terms of product dev think about users. In terms of risk mitigation (people stealing your idea) with crowd-finding, it's part of the consumer game. So, figure out a good strategy to keep the "how" protected via patents or vague enough so users will trust you and copycats will have major hurdles copying you. If you can't do this for your particular product, have everything else in place to ship so you can easily seize first mover's advantage. Source: we just performed two successful crowd-funding campaigns on kickstarter... and we love soma. They documented their process and opened up a lot of their resources. I'm a fan of their work.

This really depends on your audience and the strength of the content. What is your video about? In general, you can start building momentum by getting your influential friends to spread the link. Then share the link with communities of your target audience (you may find the communities on Twitter, Facebook Pages, Reddit, or other forums like Hackernews). For most websites and forums, it is usually really important to get a lot of views very early on. * The details vary depending on the ranking criteria of the websites.
