How It Works
A walkthrough of BogeyHunter Mobile — from first launch to the 18th green
Two coaching modes, one coach: Course Mode for on-course voice coaching and Range Mode for swing analysis at the range. Set up your clubs in My Bag and Coach Mulligan uses your actual distances for every recommendation.
First Launch — Onboarding
When you open BogeyHunter for the first time:
- Set up your profile: name, handicap, typical miss pattern
- The coach prepares itself: Coach Mulligan's AI model is included in the app download (encrypted) and prepares itself on first launch — there is no separate download. It needs about 4 GB of free storage and runs entirely on your device.
After setup, adjust your clubs and carry distances in My Bag. Everything runs locally — no internet needed during play.
Course Mode — Voice Caddie
Course Mode is your on-course companion. Here's the flow:
Starting a Round
- Open Course Mode — the app detects your course via GPS from 11,500+ bundled US courses
- If GPS is unavailable, manually select a course
- Course info loads: par and yardage where mapped (about 6,200 courses have hole-by-hole data)
On the Course
- Ask for distance: "How far am I?" — Coach Mulligan tells you the GPS distance to the green on courses with mapped hole data
- Ask for a club: "I'm 162 out, 10mph headwind" — Coach Mulligan calculates the effective distance using your carry numbers and recommends a specific club
- Ask for strategy: "Should I lay up here?" — Coach Mulligan factors in par, distance, your bag and your skill level
- Track your score: enter scores hole-by-hole for round history
Voice Interaction
Coach Mulligan is designed for talking, not tapping:
- Hold to speak in the app, or use your AirPods/Bluetooth media button
- Speech recognition happens on-device — no audio leaves your phone
- Coach Mulligan responds through your AirPods with spoken coaching
- Keep the app open on screen, phone in a pocket or on a cart mount. Coach Mulligan answers through your AirPods.
Range Mode — Swing Analysis
Range Mode turns your iPhone into a swing analysis station with 20+ biomechanical metrics:
Setup
- Mount your iPhone on a tripod, 6-10 feet away
- Position the phone face-on or down-the-line; both work
- Tap Start Session and walk to your hitting position
- A chime plays when the system detects you and is ready
Capture
Three ways to capture: auto-detect, Apple Watch, or the on-screen button.
- Auto-detect: stand still at address, the app detects your swing and captures automatically
- Apple Watch: your Watch detects the swing and triggers capture (see Apple Watch features)
- On-screen button: walk to the phone and tap the capture button
- Audio cues confirm everything — chime when ready, beep when captured. No need to watch the screen.
- Hit as many balls as you like. Each swing is captured individually.
Analysis
- Live skeleton overlay shows body tracking in real time during capture
- Apple Vision spatial pose and hand tracking compute 20+ metrics (see the Mobile overview for the list)
- Coach Mulligan delivers coaching feedback on your swings
- During Range Mode sessions, AirPods head tracking flags "head up"
Session Summary
- When you end a session, a summary shows your swing count, duration, average tempo, X-factor, and head sway
My Bag — Club Management
Your bag is the foundation for every club recommendation:
- Add up to 14 clubs (USGA limit) from the built-in club catalog
- Set your average carry distance for each club — this is what Coach Mulligan uses
- Configure loft, lie angle, and shaft flex
- Update distances as your game improves
When you ask "What should I hit?", Coach Mulligan uses your actual carry distances, adjusts for the wind you enter or tell Coach, and recommends a club.
AirPods & Bluetooth Setup
BogeyHunter uses standard Bluetooth audio routing with bonus features for AirPods:
- Connect your AirPods, Beats, or any Bluetooth headphone normally through iOS Settings
- The app routes speech output to your connected audio device automatically
- Media button integration: use the AirPods stem tap or headphone media button to activate voice input
- If no Bluetooth audio is connected, speech plays through the phone speaker
- AirPods (3rd generation and later), AirPods Pro, AirPods Max, and recent Beats models with head tracking: head tracking activates automatically during Range Mode sessions and flags "head up"
Round History
After each round, your scores and hole-by-hole data are saved locally:
- Browse past rounds in Settings → Round History
- See scores, holes played, and course information
- All data stored locally on your device
- Deleting the app removes its on-device data (your data is included in your own iCloud device backup if you have that turned on)
