I Built a $100K/Month Android App

Building a successful mobile app does not require prioritizing iOS, as Android offers a massive, often overlooked market with significantly lower advertising costs. Steve Hoyek, founder of the AI-powered calorie counter Journable, demonstrates this by scaling his bootstrapped app to $100,000 in monthly revenue, with 80% of his user base and income originating from the Android platform. His growth strategy relies on a data-driven, systematic approach to Google Ads, utilizing install campaigns to feed the algorithm before transitioning to target CPA models. By focusing on simplicity and solving niche problems rather than chasing feature-heavy development, he maintains high conversion rates. This approach highlights the importance of rigorous attribution, constant asset optimization, and leveraging Google’s expansive digital real estate to achieve sustainable, profitable growth in a competitive app landscape.
