Rollshot

iPhone still has no built-in long screenshot outside Safari. Rollshot fills that gap without the usual traps: the three ways of making one run free all the way to export at full resolution, sticky headers are kept once instead of repeated at every seam, and a seam that might be missing content is marked instead of silently glued. What you normally do before sharing — blurring out, watermarking, keeping just the subtitle lines — happens in the same app, so you never have to move the image to another editor. There is one Pro, bought once.

• Scroll & record. Tap Start, go to the page, scroll down. Pause three seconds and the long screenshot is ready. No video is left in Photos.
• Stitch screenshots. Pick a few screenshots in any order. They are lined up by content, and the one that doesn't match is marked, not guessed.
• Web page. Paste a link and get the whole page as one image, rendered on your phone.
• Seams you can see and fix. Drag the lower part into place or delete a segment. Sticky headers kept once; status bar and scrollbar removed.
• Blur out. Brush over anything you want hidden, as pixels or blur. In a group chat, hide every avatar at once. The pixels are really gone, not covered by a box.
• Tiled watermark. Grid or staggered, with the text, density, angle, opacity and colour you choose. Added to the exported copy only; your original is untouched.
• Subtitle stitching. Keep just the subtitle line from a few movie screenshots, stacked into one image. Or hand it a video clip and every line becomes a strip.
• Export without the trap. Original, WeChat-friendly or custom width, with file sizes shown. Crop, save, share, or export a PDF.
• Nothing leaves your phone. No account, no ads, no analytics. Screenshots are picked with the system picker; no photo library permission, and your images are never uploaded.
• Made for iPad, not stretched. The long shot fills the screen while seams, cleanup, blur out and export sit beside it, so you never scroll away from the image to change a setting.
