SyncStep

* SyncStep — Learn Dances Faster

Master choreography with perfectly synced videos.
SyncStep helps dancers compare, learn, and refine moves by placing two clips side by side and automatically syncing their audio. Load your reference video and your practice take, then zoom or track to spotlight the dancer you want—no editing required.


* Compare Mode (Analyze Two Videos Together)

**One-Tap Audio Sync: Instantly align beats between videos for accurate timing comparison.

**Three View Modes: Choose from Zoom (manual pinch-to-zoom), Track (AI tracking with boxes), or Focus (tracking with originals hidden).

**Split View: Watch two dancers side-by-side with smart cropping and adjustable zoom.

**Ghost Mode Overlay: Merge both videos into a transparent overlay to reveal subtle differences in timing, angles, and form.

**Smart Auto-Zoom: Keeps small dancers readable (wide zoom range when unlocked).

**Track Mode: Draw a box—SyncStep automatically follows the dancer through the video. Perfect for duets, groups, or formations.

**Tap to Hide/Show Controls: Tap anywhere on video to hide all UI for distraction-free viewing and screen recording.

**Speed Control: Slow down or speed up both videos for study and review.

**Nudges & Fine-Tuning: Manually adjust timing offsets for frame-accurate precision.

**Mirror Mode: Flip Video A horizontally in Zoom mode for easier comparison.


* Learn Mode (Your Solo Practice Studio)

Focus on one video with tools designed for personal practice:

**Follow-Along Recording: Open a front-camera preview, use a short countdown, and record yourself while your reference video plays. Drag the picture-in-picture preview and pinch to resize; the main video stays large. Saves your camera clip to Photos (reference video is not merged into the same file).

**Practice Slots: Save custom loops and jump between tricky segments instantly.

**Speed Control: Slow down or speed up playback to master technique.

**Mirror View: Flip your video to match choreography orientation.

**Clean Controls: Smooth scrubbing, looping, and rewinding without clutter.

**Perfect for self-training and reviewing your own performance.
