About

QC Lens

Read full description

QC Lens is a private, on-device workspace for inspecting watch quality-control photos. Import a complete photo set, correct camera perspective, inspect dial alignment with a precise 12-marker grid, record concerns, work through a practical checklist, and read timegrapher photos with on-device text recognition. Every OCR result remains a draft until you confirm or edit it. QC Lens preserves imported originals. Perspective, zoom, grid, and annotation data are stored separately, and photos are never uploaded by the app. Export an annotated dial image or an editable summary when you want another opinion. QC Lens assists visual inspection. It does not authenticate watches and never makes a GL/RL decision for you.
