How a Solo Developer Built a $10K MRR App in 12 Months

In early 2024, Alex Chen had an idea for a simple habit-tracking app. With no team and no budget, he started building on evenings and weekends. Twelve months later, his app generates over $10,000 in MRR.

The App

The app targets productivity enthusiasts with a clean, minimal interface. Unlike competitors with cluttered feature sets, it focuses on three core behaviors: setting daily goals, tracking streaks, and reflecting on weekly progress.

Monetization Strategy

• Freemium model: Free tier with 3 habits, unlimited on Premium
• Annual subscription at $29.99 as the primary driver (75% of revenue)
• Monthly at $4.99 as a fallback for hesitant users
• 7-day free trial for every subscription, increasing conversion by 40%

Paywall Design Insights

Alex A/B tested his paywall extensively. The winning version showed a single annual plan prominently, with monthly tucked below. He found that showing the annual plan first increased average revenue per user by 60%.

"Most users think they want monthly flexibility, but when they see the annual savings highlighted, they convert at much higher lifetime value."

Growth Channels

Organic App Store optimization drove 60% of installs. The remaining 40% came from a small but engaged Twitter audience and occasional features on productivity blogs. Alex never spent a dollar on paid ads.

Key Takeaways

• Start simple. One well-executed feature beats ten mediocre ones.
• Annual plans with visible savings dramatically improve unit economics.
• A 7-day trial reduces purchase anxiety without hurting retention.
• ASO matters more than ads for indie developers with limited budgets.
