야디지북·국내 앱·해외 테크와의 비교 매트릭스
스코어를 줄이는 데 특화. EV/SG와 환경 데이터, PDF 출력으로 차별화.
ANSWER is not for those who want a digital scorecard or enjoy watching swing videos. It's the ultimate digital yardage book for players who are serious about improving—using expected value (EV) and environmental data (wind, altitude) as their edge.

There are many golf apps, but users have different core needs. ANSWER focuses purely on one thing: lowering your score and getting better.

With rangefinders everywhere, viewing pin distance on your phone is outdated. What matters is not distance but where the highest expected value (EV) target is—based on your skill level—planned before you play.
A pretty swing and score-making ability are different. Fixing mechanics is the coach's job. We focus solely on objective analysis of results: where you're losing strokes, using Strokes Gained (SG).
Pro players always check wind, wind speed, and elevation. ANSWER fetches real-time environmental data and integrates it into your strategic map.
Replace guesswork like "is it into the wind?" with numbers. Make precise club selection and target choices.
Export in-app maps and your strategy data directly to PDF.
Features are designed as a PDCA loop for lowering your score.
Move beyond "aim at the center." Build a play plan on the map based on expected value (EV). Find the optimal target for your level.
Lie conditions need human judgment. No auto-tracking—simple taps to input intent and outcome (shot type, putt distance, etc.) accurately.
No vague reflection. Strokes Gained (SG) quantifies where you lost strokes vs. PGA benchmark. Scatter plots identify weak spots.



Stop chasing a pretty swing. Start making the best choices.
