RankPic (https://www.rankpic.info) is an app to help users crowdsource their best photo. I've been building over the past 3 years & it's grown into a lovely community of people who help each other pick their best pictures for dating apps, professional photos etc.

I've seen some pretty fun novel use cases, such as (multiple!) people using it to pick out glasses, wedding invites & so on.

I recently completed a leaderboard function that cross compares photos from different tests using Claude, which was really impressive and scared me for my day job..

Hey Ben, this looks like a neat project/app! I'm always curious with apps like this about how financially viable it is. Seems to be a fair solution to be able to generate credits yourself by ranking and then buying more credits to get ranked, do you have any numbers or insights you are willing to share? (or have shared somewhere else before?)

Hi, thanks!

That's a great question. It is not making anybody rich, but I cover my costs and make a few hundred extra a month. I think on the order of $500+ MRR.

Besides buying credits there is also a pro membership where people choose which demographics rank them (age, location, gender), can have more tests, larger test sizes and always be at the front of the queue for ranking.

This is cool. It could be generalized into arbitrary ranking (not just photos).

Questions: how do you plan to deal with people that will randomly rank other's pictures to get credits quickly (or even build a script to do so)?

Hi! Sorry for the late response, went to bed and forgot about this post. Thanks :)

We check to make certain people aren't ranking formulaically, and if they are we invalidate their votes and ban them automatically. We also check how close people's rankings are to the consensus retroactively and do some fancy anti cheating patterns there as well.
