TTReferee

TTReferee helps you review table-tennis serves beside the court. Secure your iPhone or iPad in landscape, record the player being observed, and start a challenge to examine recent footage frame by frame. Features • Rolling recording: retain up to about three minutes of recent footage locally and freeze it when a challenge starts. • Obstruction review: step through frames, zoom and pan, select evidence, and save a JPEG, an MP4 clip and a slow-motion GIF. • Toss review: manually mark the release point and highest point to view a two-dimensional projected angle, with fine adjustments. • Camera settings: choose supported rear cameras, recording resolutions and frame rates. • Evidence: save to Photos and share through the system share sheet; optionally save full challenge recordings. • Simplified Chinese and English interfaces. Privacy and use No account, ads or subscriptions. Recordings and reviews are processed on your device and are not uploaded to a developer-operated server. Video contains no audio. Camera access is used for recording; add-only Photos access is used to save evidence you choose. Keep the app in the foreground and wait for the Recording indicator before play. Continuing play starts a new recording. Changing the camera, resolution or frame rate clears the current rolling recording. Available recording options depend on your device. Toss angles are two-dimensional projections affected by camera placement. TTReferee assists human review and does not replace an umpire or an official decision.
