An iPhone can now grade your golf swing without sending a single packet
What happened
Greenside AI runs its swing-analysis model entirely on the iPhone GPU and Neural Engine. The system measures biomechanical angles, then applies predictive modeling to recommend corrections. All computation occurs locally with or without network access.
Why it matters
Practitioners see that on-device inference removes latency and privacy concerns from motion analysis. Workflows change from cloud round-trips to immediate feedback loops that work on the range or the course. Users gain repeatable, location-independent data they can trust.
Who's doing it
Greenside AI ships its app with full offline Neural Engine processing. Users receive swing metrics and predictive adjustments without uploading video or waiting for server responses.
Try it
- Install the Greenside AI app on an iPhone that supports the Neural Engine.
- Record your swing; the app runs inference locally and displays biomechanical scores within seconds.
- Apply the on-screen corrections and re-record to measure improvement. https://www.greenside.ai/
