I've been building RankPic 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.<p>The app flow is fairly simple:<p>- upload up to 6 photos in a test<p>- pay other users in credits to get your photos ranked<p>- get credits by ranking other people's photos<p>I've seen some pretty fun novel use cases, such as (multiple!) people using it to pick out glasses, wedding invites & so on<p>-- <a href="https://apps.apple.com/us/app/rankpic-photo-ranking/id160299" rel="nofollow">https://apps.apple.com/us/app/rankpic-photo-ranking/id160299</a>...

I realized I had never done a proper show HN so wanted to officially share!
