Why Inside150
Stop guessing what to practice.
Most golfers know their score. Few know which approach distances are creating missed greens, wasted practice time, and higher handicaps. Inside150 turns your approach game into clear, useful practice direction.
Track GIR by distance
Record your approach shot zone and whether you hit the green, during the round or after the round from your scorecard notes.
Find your highest-impact zone
See which distance range gets the most attempts and where a small GIR improvement could lower your score faster.
Measure improvement over time
Use filters like last round, last five rounds, month, and year to see whether your approach game is trending up.
Practice with purpose
If you hit 45% of greens from 100–125 yards, Inside150 helps you target the work needed to push toward 47%, 50%, and beyond.
Built around simple data
Focus on the information that matters on the course: approach distance, GIR result, score, and progress by round.
Designed for golfers
A premium, low-friction experience made to support your round instead of distracting from it.
The core idea
Lower your handicap faster by knowing where your misses come from.
Inside150 is built around a simple belief: your approach-shot distance and green-in-regulation percentage tell a powerful story. When you know your most common zones and your success rate from each one, every practice session becomes more intentional.
Interested in becoming a tester?
The app is already available on the App Store with a 3-month free trial. I’m also looking for a small group of 10 golfers with double-digit handicaps to help test future updates and provide feedback for upcoming releases.
