LongShot长卷

REAL APP VIDEO / 12 SECONDS

Watch LongShot stitch a scrolling screenshot on iPhone

This is the current English app flow—not a concept animation. It starts after first-time Photos setup and shows detection, overlap validation, on-device stitching, preview, and user-initiated saving.

TRANSCRIPT

What happens in the 12-second demo

  1. Recent screenshots are detected. LongShot checks the latest screenshots after Photos access has already been granted.

  2. Real overlap is validated. The app verifies adjacent content before committing to the automatic candidate.

  3. The sequence is stitched on-device. Repeated overlap is removed and one long PNG is rendered locally.

  4. The result opens in preview. The user inspects and saves it; source cleanup remains a separate iOS-confirmed action.

TRY IT CLEANLY

The screenshot sequence still matters

Keep each image the same width and leave a recognizable overlap. LongShot does not capture or scroll another app; it stitches screenshots you have already taken. If the recent sequence is uncertain, manual selection appears instead of a forced merge.
