Everything your scorecard can't tell you

Consistency scoring, AI coaching, mental game profiling, weather-aware club tips, and a 17K+ course database. All from logging your round.

Scoring

Consistency Score — not just your total

A 0-100 score built from three components: driving accuracy, putting efficiency, and scoring discipline. Captures how you played, not just the number you posted. Two rounds can score 85 and feel completely different — your consistency score shows why.

Driving score (0-33) — fairway hit percentage weighted by difficulty

Putting score (0-33) — penalizes 3-putts, rewards 1-putts

Scoring score (0-34) — score-to-par with 1.2x multiplier on doubles+

Biggest problem auto-identified — the component dragging you down

Improvement tip matched to your weakest area

AI Coach

Harvey Penick reads your round

After every round, Claude AI generates a coaching narrative in the voice of Harvey Penick — grandfatherly, warm, pattern-focused. Not a stat dump. A 3-paragraph story about how you played and what to think about next time.

Mental Game

Five constructs that separate good from great

On specific holes during your round, you answer one quick question about your mental state. Over time, these build into a psychological profile of your golf game — benchmarked against global averages.

Commitment — did you commit to your shot, or hedge?

Routine — did you follow your pre-shot process?

Reset — after a bad hole, how quickly did you let go?

Aim — did you pick a specific target, or aim vaguely?

Steadiness — how in control did the hole feel?

Weather

Conditions that change your club

Before your round, see current weather at your course with specific club adjustment recommendations. Wind, temperature, and altitude all factored in. Your AI coaching story also accounts for conditions — an 85 in 25mph wind is different from an 85 on a calm day.

Temperature: +1 club below 55°F, +0.5 below 65°F

Wind: +2 clubs into 20+ mph, +1 into 12-19 mph

Altitude: -1 club above 3,000 ft elevation
