Generally, you can read up on the ranking algorithm in this blog post:
For this situation, it is hard to come up with a determinant revenue stream that you can confidently fit into a business model. For one, your ranking is highly dependent on the rankings of other apps. You could improve your product quite a bit, but if everyone else also improves, your ranking and revenue could stay the same.
Currently, none of our ranking criteria are metrics based (i.e. number of users), but even if that was the case, your revenue would still be determined by those metrics relative to other apps.
My best suggestion for you would be to go through the public results from our alpha run and give an honest guess about how you might rank compared to these apps, based on quality of your app and execution. For example, you may decide that you feel confident that you could rank between 3-8. When we pay out $100k USD per month (which we are in the next cohort), that means you might expect to earn between $4,200 and $12,800 per month.
It’s important to know that this would just be a guess, and the best thing you can do is just focus on building the best app possible.
