About this app

Make the range count. Bay Zero is the launch monitor companion app for golfers. Pair your Garmin R10, hit balls, and walk away with real gapping and ball flight.

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

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

Real Gapping You Can Trust
• Per-club average carry, standard deviation, distribution histograms and gap-overlap warnings.
• Sessions and your bag stay in sync. Every shot you hit feeds the bag analytics.
• Replace guessed yardages on the course with real club distances 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 do not have a screen, or as an indoor golf practice display next to 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 pure 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 and a report you can save.
• Golf Pong — a competitive multiplayer range game with cups, scoring and rounds, made for buddy sessions in the next bay.
• Play Holes — random 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 flight model, so carry numbers match what your ball actually does today.
• Haptic and audio feedback for every shot. Your eyes stay on the ball, not the phone.
• Sunlight-readable shot screen, dark theme by default.
• One auto-saved session kept locally for free users. Pro keeps every session forever.

Supported Launch Monitors
• Garmin Approach R10.
• Bay Zero is built device-agnostic. As more devices 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 do not subscribe.

Why Golfers Use Bay Zero
• Range sessions become structured. You leave the bay knowing what worked and what did not.
• 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 app and shot tracker that does not get in the way of hitting balls.

Privacy
Bay Zero is local-first. 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 BLE scanning on Android.
