- Recreational doubles players with supported Snapdragon phones
- Worth noticing
- It labels a ball IN or OUT only when confident and describes every call as a reference, not a definitive ruling.
Field notes
The workflow starts with a steady phone behind the baseline, with the full court and net in frame; during recording, the app identifies serves, hits, bounces and net contacts, then saves annotated footage to the phone gallery. The page estimates two to three minutes to render a ten-minute recording and cites a Galaxy Z Fold6 for near-immediate post-recording analysis; its sample clips were processed on a development computer, so phone output may differ.
