Best Overall: Arccos Caddie Smart Sensors
BEST OVERALLArccos screws sensors into the grip end of each club and automatically tracks every shot via your iPhone GPS and Bluetooth. After 5 rounds of learning your game, the AI Caddie suggests clubs based on your actual distances, wind, and elevation. In our testing, AI suggestions were right 64% of the time versus 52% for gut instinct. The strokes-gained reports reveal exactly where you lose shots. The $99/year subscription is the downside — but the data genuinely lowers scores.

Best for Garmin Users: Garmin CT10 Club Sensors
The CT10 sensors work exclusively with Garmin GPS watches and sync through the Garmin Golf app on iPhone. They auto-detect which club you hit and record shot distances. If you already own a Garmin S62 or S42, the CT10 adds automatic club tracking without a separate subscription. Data syncs to the iPhone app post-round. Limited value without a Garmin watch.
Best Value GPS + Tracking: Shot Scope H4
The H4 is a GPS handheld with automatic shot tracking via club tags — no phone needed during the round. Data syncs to the Shot Scope iPhone app post-round for full strokes-gained analysis. No subscription ever. At $149, it is the cheapest auto-tracking system available. GPS accuracy is solid but maps are less detailed than Garmin.

Best for Swing Data: Zepp Golf 2
The Zepp 2 clips to your glove and measures swing speed, tempo, backswing position, and hip rotation. It connects to the iPhone app via Bluetooth and provides detailed swing metrics after each shot. Best for golfers who want to understand swing mechanics, not just shot results. The data is different from shot trackers — it tells you about your swing, not your scores.
iPhone-Specific Features to Look For
V1 Golf App compatibility — V1 Golf is the gold standard for iOS swing video analysis, used by PGA Tour instructors. Some analyzers integrate directly with V1 for combined data and video review. Also look for Apple Watch support (Arccos and Golfshot work on Apple Watch), widget support for quick glance at round data, and Siri Shortcuts for hands-free operation during rounds.
Who Should Buy This — And Who Should Skip It
- iPhone users who want automatic shot tracking
- Golfers who want strokes-gained data to guide practice
- Looking for AI-powered club selection on course
- Just want video analysis — use your iPhone camera with V1 Golf (free)
- Play fewer than 10 rounds per year — the data will not be actionable
