How to Clone a Successful App and Make $12K/Month in 5 Months
TL;DR: David Attias, a former quantitative trader from France, discovered the Quitter app (helping people quit vaping) was making $200K/month after just 3 months. He validated a new niche (quitting sugar) using Google Trends and TikTok/Instagram research, then used Cursor AI to clone Quitter's design and UX in 2.5 weeks. By keeping the proven onboarding flow and changing only the colors and niche focus, he launched Stoppr targeting Gen Z French women aged 13-25. Within 5 months, Stoppr reached 60,000 downloads, 900 paying customers, and $12K monthly revenue. His distribution strategy centered on French influencers discovered through ToppyYappers.com, automated outreach via Lindy.ai, and TikTok Spark Ads to amplify viral content. The approach demonstrates how proven app mechanics can be successfully adapted to underserved markets with minimal development time using AI tools.
Key Insights
- Cloning proven apps for underserved niches (different language/market) eliminates product-market fit risk
- Validation via Google Trends + social media influencer content confirms niche demand before building
- AI coding tools (Cursor + Figma plugins) enable non-technical founders to clone complex apps in 2-3 weeks
- Copy the entire UX flow (onboarding, screens, structure) but change niche - don't compete directly with the original
