DanceFlow turns dance videos you are allowed to use into focused practice — then lets you film your own version. Choose a routine from your device. Break it into sections and drill each one until it sticks, then chain them together. PRACTICE THE WAY IT ACTUALLY WORKS • Slow it down — 50% to 100% speed, same pitch • Mirror mode — flip the video so "their left" is your left • Loop a section — repeat one 4- or 8-count until it's automatic • Build up — master one section, then add the next TRACK REAL PROGRESS Mark each section mastered as you go, so you always know what to run next. TRIM TO WHAT MATTERS Upload a clip and trim it to just the part you're learning before it processes. FILM WHAT YOU LEARNED (DanceFlow Pro, iOS 18 or later) • Record yourself with the dance on screen — side by side, in the corner, or full size • Count-in timer, front or back camera, and slower paces while you learn • Set your camera brightness with one slide; Auto puts it back • Record several takes per section and pick your best • Compare your takes with the original • Export your best takes as one video to Photos, with the song FREE AND PRO Free includes every practice tool with a small routine library. DanceFlow Pro adds unlimited routines, Film, and importing a supported TikTok, YouTube, or Instagram post link — including from the iPhone share sheet.
