I Built a $100K/Month Android App
Steve built Journalable, an AI calorie tracking app that generates over $100,000 monthly in revenue with 80% coming from Android users. He focused on Android due to lower advertising costs and comparable conversion rates to iOS, scaling through Google Ads while maintaining a bootstrapped approach.
Summary
Steve, co-founder of Journalable, built an AI-powered calorie counting app that reached over $100,000 in monthly recurring revenue within 18 months, with approximately 1 million downloads and 30,000 active subscribers. The app allows users to track calories and macros by typing in foods or taking pictures, using AI to analyze and calculate nutritional information. What makes Steve's story unique is that 80% of both users and revenue come from Android, contrary to conventional wisdom that iOS users are more valuable. Steve and his co-founder, both having personal weight loss experiences, identified complexity as the main problem with existing calorie tracking apps and focused on simplicity as their core value proposition. Being bootstrapped and capital-constrained, they discovered that while iOS advertising costs are 4x higher than Android, iOS users only convert about 20% better, making Android much more cost-effective for customer acquisition. They validated their product through a Product Hunt launch, then scaled primarily through Google Ads campaigns across Google's entire advertising network. Steve outlines a detailed six-step playbook for Android app growth: setting up attribution and measurement, launching install campaigns, optimizing assets over time, implementing target CPA campaigns, scaling budgets based on performance data, and continuously optimizing conversion rates. He argues that Android represents an untapped opportunity because most new apps are being released on iOS (5x increase vs 2x for Android), creating less saturation. The tech stack is heavily Google-focused, using Firebase, Google Cloud Platform, RevenueCat for subscriptions, and OpenAI for AI functionality, along with various operational tools totaling under $400 monthly.

$77K/month founder explains why most apps NEVER TAKE OFF
Marc Loui, a $77K/month solopreneur, argues that most app creators fail because they become emotionally attached to their first idea and spend years waiting for it to succeed. Instead, he advocates for rapidly launching multiple projects, as each new attempt teaches valuable lessons and builds audience, increasing the odds that one will eventually take off exponentially faster.
