Mojenn DeckCheck vs DeckVision

DeckCheck is a fast playing card scanner that verifies that no cards are missing from your 52-card English pattern decks (i.e. J, Q, K, A). Simply spread the cards on the table and point your camera at them!

DeckVision turns your iPhone into a playing card training data collector. Point the camera at any arrangement of cards, and DeckVision automatically detects and labels each one in real time using on-device machine learning. When detections stabilize, the image is captured automatically -- no tapping required. Every captured image goes into a review queue where you can inspect bounding boxes, correct misidentified cards, and delete false positives before they pollute your dataset. Edits are non-destructive, and you can return to any image at any time. When your dataset is ready, export everything as a single zip file in Create ML object detection format. The archive includes all annotated images, an annotations.json file with bounding boxes and card labels, and a metadata.json file with detection confidence scores and correction history for full provenance tracking. Key features - Real-time card detection with automatic capture when the scene stabilizes - Full annotation review and correction after each scan - Browsable image library with thumbnail grid and detail editing - Create ML-compatible export with annotations and metadata - 100% on-device processing -- no data ever leaves your iPhone - Camera permission managed transparently, revocable at any time DeckVision is built for machine learning practitioners, researchers, and anyone working to improve playing card detection models with real-world, human-verified training data.
