About this app

Make the range count. Bay Zero turns your Garmin R10 into a complete range companion — pair your launch monitor, hit balls, and walk away knowing your real club distances, gapping and ball flight.

Built for golfers who already own a launch monitor and want a fast, focused app for the driving range and home practice. Not a swing coach. Not a social feed. Just clean shot data and live tracking, the way it should look.

LIVE SHOT TRACKING
• Pair your launch monitor and watch every shot land the moment you hit it.
• Carry distance, ball speed, club speed, smash factor, launch angle, spin rate, spin axis, apex and descent angle — every metric the R10 sends, in one clean view.
• Auto-detects your club, builds dispersion patterns and computes carry, apex and shape on the fly.

KNOW YOUR REAL CLUB DISTANCES (GAPPING)
• Per-club average carry, standard deviation, distribution histograms and gap-overlap warnings.
• Your bag and your sessions stay in sync — every shot you hit feeds the gapping analytics.
• Stop guessing yardages on the course. Play to real club distances measured from your own swings.

VIRTUAL RANGE
• A clean 2D driving-range view of your shots, ball flight and dispersion.
• Use it as a home-simulator visualiser when you have no screen, or as an indoor golf practice display beside a hitting net.
• Replay any session shot by shot.

SMARTER PRACTICE MODES (PRO)
• Speed Training — a no-ball-required mode that uses the R10 to coach swing speed and club head speed, with per-club benchmarks that climb week by week.
• Gap Test — a structured 5 or 10 shot protocol per club that rebuilds clean, balanced gapping into a report you can save and compare.
• Golf Pong — a real-time multiplayer range game with cups, scoring and rounds, made for buddy sessions in the next bay.
• Play Holes — procedural holes where your real shots, constrained by your own bag gapping, decide the outcome.

BUILT FOR THE RANGE
• Auto weather: temperature, altitude and humidity feed the ball-flight model, so carry numbers match what your ball actually does today.
• Haptic and audio feedback on every shot — your eyes stay on the ball, not the phone.
• Sunlight-readable shot screen, dark theme by default.

SUPPORTED LAUNCH MONITORS
• Garmin Approach R10.
• Bay Zero is built device-agnostic. As more launch monitors are added, your bag, your sessions and your gapping carry over with no rebuild.

BAY ZERO PRO
• Unlimited session library — every range visit you record stays in your history, ready to compare.
• All structured modes: Speed Training, Gap Test, Golf Pong, Play Holes.
• CSV export — your shots are yours.
• 7-day free trial. Anything you record during the trial stays in your library forever, even if you don't subscribe. Free users keep one auto-saved session.

WHY GOLFERS USE BAY ZERO
• Range sessions become structured — you leave the bay knowing what worked and what didn't.
• Real club distances replace guesswork on the course.
• Ball flight you can actually see, with carry and shape called out shot by shot.
• A focused range shot tracker that stays out of the way while you hit balls.

PRIVACY
Bay Zero is local-first. Your shots, sessions, bag and gapping live on your phone. Location is used only to look up local weather for the ball-flight model. Nothing is uploaded, nothing is sold, no accounts, no third-party analytics.

REQUIREMENTS
• Android phone with Bluetooth Low Energy.
• A Garmin Approach R10 (more launch monitors coming).
• Location permission for Bluetooth scanning.

What’s new

More realistic total distance.

Roll physics recalibrated to dry-fairway conditions. Driver shots now roll out further after landing, irons get proportional rollout, wedges still check up. Carry from your Garmin Approach R10 is unchanged. Only what happens after the ball lands is new.
