Dance Drill vs Re

AI scores your dance against any reference video — pose, sharpness, and beat-sync — out of 100, joint by joint. Mirror it, slow it, loop the tough phrase, and master the choreography faster. Built for K-pop covers, hip-hop crews, cheer squads, ballet & jazz students, and dance teams chasing precision in their routines. KEY FEATURES ◆ Auto Audio Sync Automatically aligns playback timing between your video and the template using audio cross-correlation. Fine-tune manually if needed. ◆ Overlay & Side-by-Side Toggle between an overlay view with adjustable opacity and a side-by-side comparison — one tap to switch. ◆ AI Pose Estimation Leverages Apple's Vision framework to detect full-body poses (15 joints) frame-by-frame in both videos. ◆ Comprehensive Scoring Get a score out of 100 that combines pose accuracy, movement sharpness, and beat synchronization. Drill down into per-joint scores to find your weak spots. ◆ Skeleton Overlay Scrub through frames with template and user skeletons overlaid to see exactly which joints are off. ◆ Beat Visualizer & 8-Count Display Automatically detects BPM and beat positions from the video's audio track. The screen border pulses in sync with the beat, with downbeat emphasis. An 8-count number overlay at the top center keeps you oriented in the phrase while dancing. ◆ Enhanced Video Player Play/pause, 10-second skip (forward & back), and frame-by-frame advance. Horizontal and vertical mirror, slow-motion (0.25x–2x with pitch correction), loop playback, and AirPlay support. ◆ IN/OUT Loop Points Set a precise start (IN) and end (OUT) to loop any section of the video. Focus on tough phrases without replaying the whole clip. ◆ Bookmarks Tap to bookmark any moment. Long-press to view your full list with editable notes. ◆ Video Export Save overlay or side-by-side composite videos to your Photos library — perfect for sharing on social media. ◆ Team Video Management Import practice videos into your library and organize them by team folders. Auto-suggests the best team based on recording time and your practice schedule. WHO IS THIS FOR? • Dancers learning choreography from video tutorials • Anyone wanting objective feedback on their dance technique • K-pop, street, and creative dance practitioners • Dance instructors comparing student performances All processing happens on-device. Your videos are never uploaded to any server.
