And I still think you're putting way too much emphasis on virality as a marketing strategy. Product placements are almost universally NOT the Toks that go massively viral, and even when they do, it's not as big of a payoff as you're hoping. One million views will result in 100-300 people actually trying the app, and at least half of those users will drop off within a matter of days. So, your entire strategy is to pay other people lots of money in hopes of an extremely rare event that gives a marginal bump in users (if you're lucky).

Even traditional paid advertising is far, far more effective than that, and you'd only be paying ~$2 per customer acquisition.
