Starter Story · How I Built It: $400K/Month iOS App ↗

What It Is

Build a simple mobile app that solves one problem you personally have and sell it on annual subscriptions. The founder interviewed made a screen-time app with a digital pet brain that "rots" the more you use distracting apps, adding a small bit of friction before opening them. He built it in a few weeks, launched to an Instagram following he had grown beforehand, and scaled with influencer content and paid ads, studying analytics to find what his most engaged users did. The episode says it grew from about $10K to about $400K a month in roughly a year.

The Pitch

The founder says a focused utility app with one core function, used daily or with high lifetime value, is the best first bet, and that small onboarding and paywall experiments compound over time.

Who It’s Best For

People who can build or manage app development (or have a technical co-founder), already have some audience or ad budget, and can stay with one product for a long time.

The Truth (as we see it)

The revenue figures are the founder's own and unaudited, and this is a standout outcome, not a typical one; most consumer apps earn little. His launch leaned heavily on about 100,000+ Instagram followers built beforehand, which most beginners don't have, and growth came from paid ads and influencers, which cost money. The advice (solve your own problem, watch analytics, run many small experiments) is sound. The interview channel promotes its own free idea database in the episode.
