Gridproof: Contact Sheets

Version-specific help

Version 5.0 (build 10)

This guide covers version 5.0. The current website catalog lists version 5.0. Check the App Store for availability on your device; the features below require version 5.0 or later.

Version 5.0 for iPhone and iPad is available on the App Store as of November 4, 2026. Mac 4.0 is separately in Apple review, with Mac 3.1 currently available. The 5.0 proof-round instructions apply to iPhone and iPad; they are not yet available in the Mac edition.

Create a project and add photographs from Photos or Files. Mark Keep, Maybe or Drop, stars and client picks; compare two frames. Design a sheet, open Deliver and build a PDF. In 5.0, Preview and deliver on the project screen opens this flow. Up to 500 photos per project and 100 projects. RAW support depends on your operating system.

In 5.0, build a contact sheet, choose Save this proof round and enter a name. Saved proof rounds holds the exact PDF, CSV and original photo-number map from that delivery. Later project edits do not rebuild or change those files. Open a saved round to view or share it.

For a numbered reply to a saved proof in 5.0, open that saved round, enter the numbers printed on it, choose Review client picks and confirm. This uses the original photo identities after reordering. Numbers excluded from that proof cannot select a different photo. Removed photos are reported and skipped. Existing client picks remain selected. The separate Read client picks screen reads compatible returned PDF tick boxes or numbers from the current project order.

Proof-round storage is limited to 20 rounds and 256 MB per project. Export older PDF and CSV files before deleting a saved round. This does not change project photographs or copies already shared. Unreadable records are preserved. If a saved PDF or CSV has changed, verification blocks opening or applying it.

In 4.0 and later, export a project JSON backup from the project menu or Backup and recovery. It includes preview images, decisions, metadata and settings, up to 250 MB. It does not include full-resolution originals. In 5.0, saved proof rounds are also excluded from JSON backups and duplicated projects; share those PDFs and CSVs separately.

Import project backup validates the file and restores a separate project without replacing existing work. Missing images, checksum mismatches and unsupported backup versions are rejected. Removed projects remain in Recently removed until restored or permanently deleted. In 5.0 their saved proof rounds move and restore with the project. Removing the app deletes local records; keep independent copies elsewhere.

Keyboard culling supports iPad and Mac: P/M/X/U decisions, 0–5 stars, 6–9 colour labels, arrow navigation and Command-Z undo. The Mac edition provides native menus, printing and Save As. Mac availability and versions can differ from iPhone/iPad; the catalog version and size describe the iPhone/iPad listing.
