Swing analysis apps: are they actually useful, or just expensive toys?

Let me answer the headline question directly before reviewing the specific apps: swing analysis apps are useful supplements to professional coaching. They are not substitutes for professional coaching. Any app that suggests otherwise is overselling its capability.

With that established, here is what the best swing analysis apps actually do well.

V1 Golf (£0 free tier / £9.99/month Pro): The most widely used swing analysis platform in professional coaching. The free tier gives you video recording at high speed (using your phone's slow-motion capability) and basic drawing tools to annotate the swing. The Pro tier adds AI swing analysis (automated identification of swing plane, hip turn, and face angle from video), cloud storage, and coach sharing. The AI analysis is genuinely impressive — it correctly identified a swing plane issue in my own swing that two coaches had noted previously. But the value of V1 is primarily as a communication tool between player and coach: you film your swing, your coach reviews it remotely, annotates it, and sends it back. The AI is a useful first filter but should not replace the coach.

Hudl Technique (free): The most popular free sports analysis app, used across dozens of sports. Golf implementation is solid — slow-motion capture at 120/240fps on modern phones, side-by-side comparison tools (put your swing next to a tour pro's at address), and basic annotation tools. It lacks the golf-specific AI of V1 but is free. For golfers who want to film their swing for self-analysis or to share with a coach, Hudl Technique is the starting point.

Swing Profile (£9.99/month): A dedicated AI swing analysis app that attempts to provide coaching feedback without a human coach involved. The AI categorises your swing against common fault patterns (over the top, early extension, reverse pivot, etc.) and provides text feedback. In my testing, it identified genuine issues in a 12-handicap client's swing correctly in approximately 70% of analysis sessions. The remaining 30% produced generic feedback or misidentified the primary fault. At 70% accuracy, it is useful as a self-analysis tool but should trigger a lesson with a professional, not replace one.

The honest position: film your swing with any of these apps, compare it to your on-course performance data from Arccos or Shot Scope, and bring both sets of evidence to your next coaching session. A coach who can see your swing video AND your real performance data (scoring patterns, miss tendencies, Strokes Gained breakdown) delivers significantly better lessons than a coach who watches you hit balls on a range without any data context.

One travel application: I film at least one swing from each major club during the first round of every new destination. Differing lie angles, firmness, and altitude (particularly in South Africa and the Alps) affect ball flight in ways that your home-calibrated swing doesn't account for. Video comparison across different conditions is the fastest way to identify adjustments needed.
