DanceFlowW vs Stemify AI

DanceFlowW helps you study the music and movement in your own practice videos, then repeat the part that needs work. HEAR THE MUSIC IN LAYERS • Import a video or audio file up to two minutes. • Separate vocals, melody, bass, and drums on your iPhone. • Adjust each stem, listen to one part, check BPM, and follow the 8-count. PRACTICE THE PART THAT NEEDS WORK • Slow playback, loop a section, or mirror the video. • Add HIT, WAVE, STEP, FREEZE, or custom markers without losing your place. • Keep video and audio aligned while you seek, pause, resume, or change speed. COMPARE MOVEMENT IN 3D • Choose a teacher and student from the frame. • View both skeletons separately or overlaid. • Adjust overlay spacing and compare timing at the same video moment. • Open the focused practice video after processing finishes. CONTROL YOUR PROJECTS AND DATA Audio separation and local project files are processed on your device. 3D learning uses account-based private upload and cloud processing. You can stop a submission, delete projects and cloud assets in the app, and review data handling in the Privacy Policy. DanceFlowW is made for dance students, teachers, choreographers, and crews who want to hear the count, inspect a move, and repeat it.
