Sportsbox 3D is the reference if you want validated biomechanical 3D analysis ($15.99/month), and OnForm if you mainly want coach-student collaborative video ($9.99/month).
Between $9.99 and $59.99/month depending on the app (July 2026): OnForm $9.99, Swing Coach $14.99, Birdia €14.99, Sportsbox 3D $15.99 and SwingIQ $59.99. Most have a limited free tier; compare what each plan actually includes before paying.
Three things, with the disclosure that it is our product: (1) causal diagnosis — it tells you WHY each fault happens, not just that it happens; (2) every recommendation comes from a cited knowledge base (Hogan, Leadbetter, Pelz, TrackMan, TPI…), visible in the app; (3) it measures with the phone camera on-device, no sensors. What it does not have yet: 3D analysis is in development — Sportsbox still leads there.
