Need a contact sheet of your photos β to proof a shoot, pick favorites with a client, catalog an archive or print an index of a trip? Sheetly lays your photos out in a numbered grid and exports a print-ready PDF or JPG pages in seconds. Select up to 100 photos, choose a grid, page size and captions, put them in the order you want, and create the sheet. β’ EIGHT GRID SIZES β from 2 Γ 2 (4 per page) up to the classic dense 5 Γ 7 (35 per page), including 3 Γ 3, 3 Γ 4, 4 Γ 4, 4 Γ 5 and 5 Γ 5. β’ NUMBERED THUMBNAILS β every photo gets an index number, so βnumber 14β means the same photo to everyone looking at the sheet. β’ CAPTIONS β show the number only, the file name, the date the photo was taken, or name + date. β’ WHOLE PHOTOS, UPRIGHT β each thumbnail is fitted inside its cell without cropping and turned the right way up. β’ LETTER OR A4, 300 DPI β pages are rendered at 300 DPI for sharp proof prints; photos flow onto as many pages as needed. β’ YOUR ORDER β reorder the photos before you export; the first one is number 1. β’ PDF OR JPG β one multi-page PDF, or one JPG per page. Share, save to Files, or save the pages to your photo library. Good to know: photos are chosen with the system photo picker, so Sheetly never needs access to your whole library; it only asks for permission to add images when you save pages to Photos. Thumbnails are for proofing and reference β they are not full-resolution prints of your originals. File names and dates appear only when the photo provides them. Everything happens on your iPhone β no uploads, no account. Try it free β 3 exports. A one-time $4.99 purchase unlocks unlimited contact sheets. No subscription, no ads.

Gridproof

Gridproof turns a shoot into a decision: cull it fast, then deliver a clean contact sheet your client can answer. Everything happens on your iPhone or iPad. No account, no uploads, no subscription. NEW IN 3.0 - Full-screen culling: Keep, Maybe or Drop with one tap, 1-5 stars, color labels and client picks. Auto-advance, swipe, pinch or double-tap to zoom, and undo. - iPad keyboard shortcuts: P keep, M maybe, X drop, U clear, 0-5 stars, 6-9 color labels, arrow keys to move, Command-Z to undo, C to compare. - Compare two frames side by side with one shared zoom to check focus and expression. - File names and camera data: Gridproof keeps the original file name (from Files, and from Photos when it provides one) and reads capture time, camera, lens, focal length, aperture, shutter and ISO. - Import from Files: JPEG, HEIC, PNG, TIFF and the RAW formats your device can open. - Bigger projects: up to 500 photos per project, with autosave. Your 2.0 projects move over automatically. - Sheet designer with live preview: US Letter, Legal, Tabloid, A4 or A3, portrait or landscape, 1-8 columns and 1-10 rows, light or dark sheet, your studio name and contact line, watermark text, and presets for contact sheets, client proofs, print selects and dark film-style sheets. - Choose what goes on the sheet: every photo, all but Drops, Keep and Maybe, Keep only, client picks, or a minimum star rating. Labels under each photo: number, decision and stars, file name, exposure, capture date, caption. - Client tick boxes: proofs can carry a real PDF check box under every photo. Your client ticks the ones they want in a PDF app that fills forms and sends the file back; Gridproof reads the ticks and marks those photos. Clients who reply with numbers instead ("3, 7, 12-15") are covered too: paste the reply and Gridproof finds the photos. - File name lists for your editing software: comma-separated names for a text filter, one name per line, or photo numbers. Copy or share. - Deliver as PDF, a JPEG per page, or straight to a printer. The CSV lists every photo with its decision, rating, label, client pick, file name and camera data. - Shortcuts action "Make Contact Sheet": give it images, get a PDF back. - Faster grid, filters for Keep, Maybe, Drop, Undecided, client picks and 3+ stars, reorder by capture time, file name or rating, duplicate projects, and VoiceOver actions on every photo. HOW IT WORKS 1. Create a project and add photos from Photos or Files. 2. Cull full screen or right from the grid. 3. Design the sheet, then build the PDF, share it with the CSV, print it or send JPEG pages. 4. When the client answers, read their ticks or numbers back into the project. WHAT TO KNOW Gridproof stores resized preview copies (up to 1200 pixels on the long edge) with your decisions. Sheets are for proofing and selection, not original-resolution delivery. Originals in Photos and Files are never edited or deleted. Photo numbers follow project order, so filtered sheets can skip numbers; the CSV always lists every photo. Filling in PDF check boxes depends on the client's PDF app; numbers work everywhere. iPhone and iPad. No account, no tracking, no ads.
