We Built This $20K/Month App (Zero Coding Experience)

Christian (20) and Braylin (19) are college sprinters with no coding background. They built 3AK, an all-in-one track and field app (plans, workout and form tracking, AI video form scoring, meal analysis, community), in about two weeks with Rork and Claude. Launched Dec 16, it made $10K in month one and about $70K in ~6 months, with ~40K users and a 4.7 rating. Growth came from the hundreds of thousands of track followers they had built with videos. They had seeded the 3AK brand in those videos through an earlier Shopify store.

Build the first app just for track athletes, a sport you already run and post about

Founders say it worked; ~$70K in ~6 months

“We realized a lot of people run track, but there's no apps for track and field specifically. So we said, let's put our app where we already have influence right in the niche.”
