Round entry
Hole-by-hole wizard with real-time strokes gained
Enter each shot by lie type and distance. The app calculates strokes gained on the fly so you can see where you're losing strokes as the round unfolds.
- Eight lie types: tee, fairway, rough, deep rough, sand, recovery, green, penalty
- Yards or meters — switch on your profile
- Penalty and drop flow for OB, water, and lost ball (including two-stroke E-5 drops)
- Edit any past round — reopen the wizard and adjust shots
Voice / AI shot entry (experimental)
Dictate a hole in natural language and Claude parses it into shots — lie, distance, and result per stroke. Useful when you want to enter a round after the fact.

Sharing and access

Offline shot entry (web)
Spotty signal at the course? Shots entered offline are queued in local storage and sync automatically when you reconnect. Built on IndexedDB + a service worker for the PWA.
What makes this different
Most strokes gained tools compare you to a PGA Tour player or a scratch golfer. That makes positive numbers nearly impossible if you're a mid-handicap, and it hides the information that actually helps you practice.
Data Driven Golf scales the expected-shot benchmarks to your target handicap and the specific course you're playing (rating, slope, yardage). Read the How It Works page for the formulas, or jump to the FAQ.
