Sewn

Stitch screenshots into one tall image. Everything runs on your phone, offline.

Three modes. Document: article and web-page screenshots; repeated parts are removed and, where two screenshots do not overlap, the seam is padded to the text's own line or paragraph spacing, without altering the images. Long screenshot: screens scrolled through one app; repeated top and bottom bars are cropped, the pieces are joined at their overlap and the scroll indicators are painted over; a seam without overlap is flagged in red. Smart: text recognition; chat screenshots with time stamps are sorted by time, and the text can be re-laid out as one clean image.

Taking screenshots that stitch well: after each screen, scroll so a little of the previous screen is still visible; the order does not matter (screenshots are sorted by the time they were taken, and screens captured while scrolling up are reversed automatically); select them all at once from Photos, up to 30.

Questions. Wrong seam? Tap its label in the preview and drag the slider, with a live close-up; if the app has matched two passages that only look alike, switch off "Remove the overlap". Bars not fully removed? Set the top and bottom crop by hand under Adjust → Crop. Export as PNG (lossless) or JPEG (smaller; images over 65535 rows are PNG only), to Photos, the share sheet or the clipboard. Images are picked through the system photo picker, so no library permission is needed; saving uses the add-only Photos permission. See the privacy policy.
