Growth strategy behind a $15K MRR mobile app | Starter Story

When you launch a mobile app, the temptation is to build features for everyone. But the founder behind Habit Kit, a habit-tracking app that grew to $15,000 in monthly recurring revenue, took the opposite approach: he focused relentlessly on a single keyword, a single user action, and a single moment of success. The result was a lean growth engine that didn't require paid ads or a marketing team.

The Keyword That Changed Everything

The core of Habit Kit's growth strategy was App Store Optimization (ASO), which the founder describes as "basically editing your app store metadata like keywords, app name or subtitle, or even the screenshots in the way that you're more likely to rank in the top spots when people search for certain keywords." Instead of trying to rank for broad terms like "productivity" or "self-improvement," he zeroed in on one specific keyword: "habit tracker."
