Offering a free Lifetime deal

So the whole story is that when we launch in about a month we will need plenty of users to test our offering. We will be launching 20 seed apps on our platform. They will not be launched all at the same time but offering a free lifetime deal allows us to see what people are most interested in and so what app we can launch first.

We launched a small budget google ads campaign and signing up users at less than 5 usd / user.
current count is 63 signup/invite requests.
