KinePair: Motion Compare
Side-by-Side Video Analysis
Free · In‑App Purchases
Compare. Sync. See the difference. Review two movement videos side by side, stacked, or overlaid with private, on-device processing.
KinePair helps coaches, athletes, trainers, and movement professionals compare two videos with precision.
Choose two videos, set a reference point in each, and review the same moment with synchronized playback. View movements side by side, stacked, or overlaid, then inspect the details with slow playback, frame stepping, and loop controls.
KEY FEATURES
- Synchronize two videos using independent reference points
- Compare side by side, stacked, or overlaid
- Seek and control both videos together
- Use slow playback, precise frame stepping, and loop ranges
- Zoom and pan each video
- Adjust overlay position, scale, rotation, and opacity
- Save local comparison history
- Export images and MP4 video
PRIVATE BY DESIGN
Videos are processed on your device. Copies used for comparison history stay inside the app and are never uploaded to a server. KinePair requires no account and includes no advertising, analytics, or tracking.
TRY THE FULL EXPERIENCE
Your first three comparisons include all KinePair PRO features. After that, basic side-by-side and stacked comparison remains available for free. KinePair PRO is a one-time purchase that unlocks overlay comparison, slow playback, loops, additional frame-step intervals, multiple history items, watermark-free 1080p images, and MP4 video export.
KinePair is a visual comparison tool. It does not provide medical advice, automatic posture analysis, or performance diagnosis.
