Scrubwave

Scrubwave scans any video on your device and turns motion, audio, and face activity into a single heatmap timeline, so you can find the best moments in long or unedited footage without scrubbing through it by hand. Tap anywhere on the heatmap to jump straight to that moment. Swipe to scrub frame by frame. Every clip you analyze is saved to your library with its own activity map, ready to revisit. Built for anyone triaging raw footage before editing: vloggers, parents with hours of family clips, coaches reviewing practice tape. Everything runs fully on-device — no account, no uploads, no cloud processing. FEATURES • Multi-factor activity heatmap combining motion, audio level, face presence, and scene cuts • Tap-to-seek and swipe-to-scrub navigation • A saved library of every video you've analyzed, each with its own heatmap • Adjustable weighting to tune how each signal contributes to the heatmap • Auto Highlights: one tap turns your best moments into a separate highlight reel • Batch mode: analyze multiple videos in one pass Scrubwave doesn't edit, render, or export your original video — it's a discovery tool that helps you find the good parts fast, then hands off to whatever editor you already use.
