Make every practice more focused with Duolian. Built for table tennis and badminton players, Duolian brings match recording, rally review, technique comparison and training records together. Look back at your session and find what to work on next. REVIEW YOUR MATCH, RALLY BY RALLY Record or import match videos. Intelligent rally segmentation turns long recordings into clips that are easier to review. Save your matches and analysis records to revisit your performance. COMPARE YOUR TECHNIQUE Choose a reference movement or compare two of your own videos. Use frame-by-frame playback, skeleton overlays and angle information to spot differences. Cloud-based 3D Body comparison lets you explore movements from different perspectives. KEEP TRACK OF TABLE TENNIS MATCHES Scan a code to start a match with another player, record and confirm scores, then review the match video by rally.
