A closer look at every edge • Automatic frame suggestions give you a starting point. • A focus magnifier and fine controls help you position each border. • Rotation and perspective controls help you work with angled photos. • See horizontal and vertical centering ratios and compare reference standards in the guide. • Choose guide colors and styles that remain visible on your card. Keep your collection organized Save scans locally, search your records, pair front and back photos and share measurement images with visible guides.

Available plans and local prices appear in the app. Subscriptions renew automatically unless canceled; manage them in your Apple account settings. Card analysis runs on your device without an account. If you enable detection improvement sharing, cropped card images and your frame corrections can upload automatically to help improve detection. Sharing is off by default and can be disabled in settings. App interface languages: English, Japanese, Korean, Vietnamese, Simplified Chinese and Traditional Chinese. Check suggested borders before measuring. Lighting, sleeves, perspective and card design can affect detection; full-art cards may lack a measurable printed inner border. CenterMint estimates centering only, not surface condition, corners, edge wear, authenticity or a full professional grade. It is an independent collector’s tool and does not guarantee a grading outcome.
