A golf strategy app that turns shot dispersion and course data into better on-course decisions golfers will pay to make.
Hit $1M in total sales · $100K net income in one summer
Build for the golfer already measuring shots on Google Maps, then put that strategy in their hands on the course.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Eric Duffett began building apps in 2015 and put his first app in the App Store in 2016. Years of experiments, including a meditation app for high school athletes, taught him that a sincere problem is not enough when the intended users do not see it as urgent. Shot Pattern came from a frustration he knew firsthand: he planned golf holes on Google Maps, then arrived at the course without those notes or a way to adapt the plan. He built an app around strategy and shot-pattern analysis for competitive golfers. The first version took three weeks to develop and focused on two features rather than a full golf suite. Duffett aimed for $1,000 that summer and reached it by the end of June. After buying $5,000 of golf-course data, he found a way to model shot outcomes using both a golfer's data and the course. He later turned down a $75,000 acquisition offer, expanded shot tracking, and tested subscriptions, onboarding, and paid ads. He reports that sales are now close to $1 million a year.
Shot Pattern first reached golfers through Twitter posts and replies in conversations where strategy-minded players were already discussing the game. Duffett did not need to explain why golf analytics mattered to that audience; the product answered a behavior they already had.

Data credibility: Eric Duffett reports close to $1 million in yearly sales, $1 million in total sales, and $100,000 in net income for one summer. These are founder-reported figures from an interview and were not independently audited. He also described turning down a $75,000 acquisition offer; it was not a completed sale.
The first revenue came from a narrow app launched after three weeks of development, not from a large feature set. Duffett had a modest target: $1,000 over the summer to offset the cost of playing golf.
The growth loop joined product specificity, measurable conversion, and creative that demonstrated a real golf decision. Duffett built features around requests from competitive golfers, then showed those features in short videos instead of relying on polished brand ads.
Duffett spent years building apps before he found a market that was ready to pay. His meditation app for high school athletes took four or five years to expose the mismatch: students did not recognize the problem as theirs to solve, and young users were less likely to pay.
