Heatreel turns long, boring video into short highlight reels — automatically. Import security-camera footage, a time-lapse, or a dashcam clip, and Heatreel analyzes motion frame by frame right on your device, then draws it as a vertical heatmap you can scrub with one gesture. Warm colors mark real motion; cool colors mark the stillness you can skip. Tap a hot spot to preview it instantly. Drag the sensitivity slider to catch subtler movement or isolate only the biggest bursts. Extract one clip in the base app, or unlock Pro (requires an in-app purchase) to batch-export every detected segment at once, merge them into a single highlight reel, and fine-tune advanced motion thresholds. Everything runs fully on-device. No account, no uploads, no cloud processing — your footage never leaves your phone. Privacy Policy: https://www.apple.com/legal/privacy/.

Founder quote

Heatreelis built around one principle: your data stays on your device. We don't want it, we don't store it, and we don't need it to make the app work. Everything that can run locally, does.”
— Peter Zhang, solo developer, Obelisk Club
