SuperShot vs PreviewMD

Turn screenshots into a story worth sharing. SuperShot combines long screenshots, image stitching and markup on iPhone and iPad. Save a conversation, collect web references or explain a process with clear visual steps. Save editable projects, create named checkpoints and back up or restore your work. Reuse presets, process images in batches, and use saved workflows or layouts for tutorials and comparisons. Import selected PDF pages and adjust image exports with target file size controls. Edit table rows and columns, then export multiple tables in one XLSX workbook. LONG SCREENSHOTS AND STITCHING Choose Scrollshot to detect and remove overlapping areas between screenshots, then adjust the joins manually if needed. Horizontal and Vertical arrange complete images side by side or top to bottom without automatically cropping their content. Turn a scrolling screen recording into a long image. Capture full webpages through the Safari extension, or trim a video clip and convert it to GIF. Crop one image in a stitched composition while the others scale proportionally to the same width or height. With a fixed aspect ratio, drag the image to adjust the framing. Add dividers or outer borders, and use the URL link builder in Settings to configure stitching, device frames and output for Shortcuts or other apps. ANNOTATE WHAT MATTERS Add arrows, text, shapes, freehand drawing, highlights and numbered steps. Use a magnifier or spotlight to focus attention. Crop precisely, resize, add watermarks and finish with backgrounds or device frames. TEXT AND PRIVACY Recognize text in an image or a selected region, translate it, and copy recognized tables as TSV or export them as CSV. Review and cover sensitive text, faces, QR codes and barcodes with privacy tools before sharing. REFINE YOUR IMAGES Extract a subject and change its background, remove unwanted objects or enhance an image at 2x resolution. Adjust filters and tidy screenshot status bars or scrollbars. PREVIEW FREELY, CHOOSE HOW TO EXPORT Try every available tool and preview the result without purchasing. Ordinary screenshot, stitch, crop, markup and OCR results remain free to save, share or copy. Outputs containing AI object removal, 2x enhancement, subject cutout, translation or table extraction require Pro. Closing the purchase page keeps your edits; undoing Pro effects restores free output. Save images or PDFs, split long images into slices and share through Photos, Files or the system share sheet. Choose a monthly, annual or lifetime Pro plan in Settings. A first-month subscription trial is available only for eligible accounts and offers; pricing and renewal terms appear before purchase. Editing, stitching and the image tools above process on device. Some tools need model or language downloads. Availability varies by device, system and language; review automatic results before sharing. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

PreviewMD is a fast, native editor and viewer for Markdown on iPad and iPhone — the same rendering as the Mac app, free on both. Open any .md file from Files or iCloud Drive, or start a new document right in the built-in browser. FOUR WAYS TO WORK • Preview — a clean reading view • Split — live preview beside the Markdown source, side by side on iPad and stacked on iPhone • Source — the Markdown alone, full width • Diff — see exactly what you've changed since you opened the file, word by word BEAUTIFUL RENDERING • GitHub-flavored Markdown: tables, task lists, footnotes and strikethrough • Syntax highlighting for almost two hundred languages • Math typesetting with KaTeX — $inline$ and $$display$$ • Diagrams with Mermaid — flowcharts, sequence, class, state, pie and gantt • GitHub-style alert callouts (> [!NOTE], [!WARNING], …) and emoji • Automatic light and dark mode WRITING ON A TOUCHSCREEN A formatting bar sits above the keyboard for bold, italic, inline code, headings, quotes, lists and links. With a hardware keyboard the same actions have shortcuts. YOUR DOCUMENTS, YOUR IMAGES Works with the Files app and iCloud Drive — documents open in place and save as you type, with no Save button to remember. Local images referenced by your document display right in the preview. EXPORT, SHARE & PRINT Export self-contained HTML or clean light-mode PDF straight to the share sheet, or print with proper pagination. QUICK LOOK Markdown files preview with PreviewMD's renderer in the Files app too. ONE APP EVERYWHERE Free on Mac as well — including Quick Look previews and thumbnails in Finder. Requires iOS/iPadOS 17 or later.
