TangoFlow is an augmented reality practice tool for Argentine Tango dancers. Remembering a movement during class is one thing. Reconstructing it later is another. TangoFlow helps you revisit tango footwork between lessons, classes, and practicas through animated footprints placed directly on your floor. PRACTICE WITH A PATH YOU CAN SEE Choose a tango flow and place its footprint pattern in your physical space using your iPhone camera. Follow the movement from your own perspective instead of trying to translate a video recorded from another angle. TRAIN AS LEADER OR FOLLOWER Switch between leader and follower views to study either role. Use TangoFlow to reinforce your usual role, understand your partner’s movement, or begin learning the other side of the embrace. CONTROL THE PACE Complex movements become easier to study when they are slowed down. Practice at full speed or reduce playback to 0.66x, 0.5x, 0.25x, or 0.1x. REPEAT THE DIFFICULT PART Select a starting and ending beat to create a focused practice loop. Repeat one transition without restarting the complete sequence every time. ADJUST THE PRACTICE FLOOR Every room is different. Scale, rotate, and reposition the AR footprint path so it fits the space available around you. BUILD MOVEMENT MEMORY TangoFlow turns a movement idea into something you can see, repeat, and physically rehearse. It can help you: • Remember more of what you learned in class • Reconstruct sequences before a practica • Practice footwork when a partner is unavailable • Break longer movements into smaller sections • Develop greater spatial awareness • Explore both leader and follower perspectives • Use lesson time for feedback instead of reconstruction DESIGNED FOR DELIBERATE PRACTICE TangoFlow is not another passive video library. Videos show someone else dancing from an external viewpoint. TangoFlow places the movement path in your own environment and gives you control over its speed, scale, orientation, and repetition. The app is designed to complement teachers, partners, group classes, and social dancing—not replace them. Argentine Tango also requires connection, posture, musicality, communication, and feedback from real people. TangoFlow focuses on helping you rehearse and remember the spatial movement underneath those skills. FEATURES • Augmented reality tango footprints • Curated library of published tango flows • Leader and follower perspectives • Adjustable playback speed • Beat-range practice loops • Floor scale, rotation, and placement controls • Searchable dance library • Free introductory flows • Monthly and annual subscription options • Apple purchase restoration and subscription management Some tango flows are available free. A subscription unlocks access to the complete published practice library. Practice slowly. Repeat intentionally. Arrive at your next class or practica better prepared.
