WHAT REALLY HAPPENS INSIDE A DATING APP

Summary from the TLDR Web Dev newsletter

This blog post goes over the inner workings of a dating app and learnings from them - both technical and nontechnical. The author discusses user ranking systems, how simple like-to-pass ratios are more effective than complex algorithms like ELO scores, and how user behavior significantly differs between men and women. App retention is heavily influenced by the feed algorithm, which must prioritize personalization over simple recommendations to maximize user engagement, particularly focusing on getting women to send likes and men to receive them.
