Show HN: RankPic – crowdsource your best photo (rankpic.info)
3 points by bengold14 558 days ago
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.

The app flow is fairly simple:

- upload up to 6 photos in a test

- pay other users in credits to get your photos ranked

- get credits by ranking other people's photos

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

It was discussed yesterday on the Ask HN thread (https://news.ycombinator.com/item?id=42373343) that got a good amount of interest, and really blew up my website views (1126 in a day vs my normal 2-6). I realized I had never done a proper show HN so wanted to officially share!

Very interesting. I am curious, how big is your community, and how did you advertise it to grow it to the point it is at currently? And how many are active, i.e., how long does it normally take before your images have been ranked?

This reminds me of https://www.photofeeler.com/

Thanks for asking! The community is about 15,000 users, maybe 100-300 DAU, tests complete in as little as 10 hours for 20 ranks or up to a couple days if you have a lot of niche filters set for your rankers (age, sex, location).

The best ROI I have found is on Apple and Android app stores. I tried Facebook, Tiktok & others and have found them very expensive with little return (though I admit I'm not marketing expert).

As for Photofeeler.. I actually created this app because I found the way it rated me 1-10 fairly harmful to my mental health. RankPic has users rank your photos best to worst, so it's just against yourself. Additionally you can get more mileage out of each test as you can upload up to 6 photos at a time.

Interesting, that is a good size userbase! And good argument regarding the ranking vs rating - did not consider this.

I have a site, app.rapidata.io/compare which has a related feature, allowing you to have 100 people vote between two images based on a question (it was made as kind of a demo for our underlying product, but maybe you find it interesting). These are mostly random people though and it does not as detailed filtering as you have.
