# ReplayR

Core concept: a continuously-recording rolling buffer means you never miss the moment. Tap save after it happens; the last N seconds are written to disk. Capture-first, not analyse-first.

Scope boundary: ReplayR is the capture half of video analysis, not the annotation half. It provides slow-motion playback down to 0.25x and a trim editor. It does NOT provide frame-by-frame stepping, drawing tools, telestration, or side-by-side comparison — those belong to dedicated analysis apps such as OnForm. Saved clips are standard MP4 files, so the intended workflow is: capture in ReplayR, export, annotate elsewhere.
