A track-specific training app turns sprint coaching and form analysis into an affordable athlete subscription.
around 40,000 users · $10 monthly / $30 yearly plans
They did not start with an app idea; they put a $10/month app in front of a track audience they had already earned with free videos.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Christian and Braylon built 3AK, an all-in-one training app for track athletes, after noticing that runners had few dedicated mobile tools. Both were college sprinters who had trained together; their firsthand experience gave them a clear starting audience and a steady supply of product problems. They say they had already built an audience of hundreds of thousands of track-and-field followers through videos, and had been putting the 3AK name in their videos, Shopify store and social bios before launch. The app combines workout and progress tracking, nutrition guidance, a community, and AI-assisted running-form and meal analysis. They report building it in about two weeks despite having no coding background, using AI tools and services including RevenueCat and Supabase. They say the app launched December 16, earned $10,000 in its first month, and had generated about $70,000 in total by the interview, with around 40,000 users and a 4.7 App Store rating. The founders describe a $10 monthly subscription and a $30 yearly plan. Their audience is young, so they tested lower-priced access rather than assuming athletes would buy expensive coaching.
For a track-training app, the first customers should come from places where athletes already trade drills, race clips, and advice.

Data credibility: Christian and Braylon report the app's approximate $70,000 total revenue (about six months after a December 16 launch), about 40,000 users, $10 monthly and $30 annual pricing, $10,000 in the first month and a 4.7 App Store rating. Starter Story shows no payment dashboard or third-party data. The video title and host say "$20,000 a month"; the founders' own specific figure is cumulative revenue to date, so this entry does not treat $20,000/month as a verified run rate.
The founders say they built the app in about two weeks and earned $10,000 in the first month. They describe a $10 monthly subscription and a $30 yearly option, positioning the paid product around practical training support rather than a high-ticket coaching plan.
3AK’s early loop links athlete content, a recognizable niche, and a product athletes can show one another. The founders say their track videos had built hundreds of thousands of followers and that they placed the 3AK name in their content and store before launching the app.
A two-week build and an existing audience can shorten the uncertain period, but they do not remove it. For a niche sports app, the dangerous stretch is often the gap between attention and repeated use: athletes may install after a viral clip, try one analysis, and disappear when the season or motivation changes.
