During my senior year in college, I wanted to build a social discovery app that helped me find the most compatible people possible to pair me up on video chats with. I envisioned using grandiose AI at the time, but settled for a simpler ranking algo.<p>After a long, long tread. I've finally hit $2k in MRR. I use firestore w/a serverless set-up, and the app scales up nicely. My profit margins are over 99.9% (aside from the 15% cut Apple is taking from me).<p>Used SwiftUI to build the entire app. I hope to make more video chatting apps like this, but man was it a TON of work by myself. I had help from one designer with logos but that's about it.<p>It was especially hard for me to balance iterating on this with my day job (I only really had time on weekends).<p>I hope it lasts for a few years and I can bank $100K from it. That'd be pretty cool
