Ultralytics YOLO - Vision AI in Your Pocket

Turn your iPhone or iPad into a professional vision-AI tool. Point the camera at the world and see it understood in real time - object detection, instance segmentation, pose estimation, image classification, and oriented bounding box (OBB) detection, all running 100% on-device through the Apple Neural Engine.

Powered by Ultralytics YOLO26 - the latest NMS-free, state-of-the-art real-time detectors from the team behind the open-source YOLO family trusted by millions of developers worldwide.

Version History - Added real-time monocular depth estimation with colorized depth maps.
- Improved performance across detection, segmentation, pose, depth, classification, and OBB models.
- Accelerated depth-map processing from approximately 70 ms to 2 ms.
- Preserved a sharp camera preview while using optimized inference resolution.
- Added high-resolution pause and sharing.
- Improved overlay positioning so labels remain visible on screen.
- General stability and workflow improvements. 8.9.12 Jul 15 Sharper, faster segmentation overlays. Segment masks now render at higher quality with optimized post-processing, cutting mask rendering time by up to 3x while keeping live camera performance smooth. Also includes reliability fixes for rapidly changing camera scenes and general performance improvements. 8.9.10 Jul 1 • New timing display: see preprocessing, inference, and postprocessing per frame under the FPS readout
• Sharper semantic segmentation: full-resolution masks with crisp class boundaries, rendered faster
• Smoother camera switching: the transition now covers the full interface
• Layout fixes: model selector sized correctly in landscape, no placeholder text or layout shift at launch 8.9.6 Jun 11 Version 8.9.4 adds camera torch control for brighter real-time inference and brings the latest YOLOView SDK updates into the app.

• Added a camera torch toggle for live YOLO inference
• Added YOLOView support for custom overlay rendering

- Added an in-app info drawer with quick links to Ultralytics Docs, YOLO26 models, GitHub, and Licensing.
- Improved model switching reliability with cancel support for remote downloads on slow networks.
- Improved loading overlay behavior during device rotation.
- Refined bottom toolbar spacing on modern iPhone displays. 8.8.8 Jun 1 - Added support for YOLO semantic segmentation models.
- Improved on-device vision workflows for dense pixel-level scene understanding.
- Includes stability and compatibility refinements for the latest YOLO model support. 8.8.7 May 22 - Dedicated external display now works in both portrait and landscape — no need to rotate your iPhone
- Camera orientation on the external screen follows your device, not the monitor
- Detection boxes, segmentation masks, pose keypoints, and OBBs are now correctly placed on external displays
- New "Dedicated External Display" toggle in iOS Settings (off by default), applied without restarting the app
- iPad landscape support 8.8.6 May 12 - Fixed YOLO camera preprocessing to preserve image aspect ratio instead of stretching frames.
- Improved portrait and landscape inference orientation so objects are presented upright to the model.
- Added better support for square, portrait-only, and landscape-only Core ML model input shapes.
- Updated YOLO26 model export guidance for iOS and Core ML.
- Improved App Store links and documentation for international users. 8.8.5 May 9 - Added an iOS-style camera lens selector for switching between available rear camera lenses.
- Improved camera switching so the rear camera returns to the expected 1x view.
- Fixed share behavior when the camera is paused, including sharing the paused frame with detection boxes.
- Improved share capture reliability while the camera is running.
- Added a quick info button linking to Ultralytics.
- Improved camera controls, zoom selector sync, and overall camera UI polish.
- General reliability and performance improvements. 8.8.4 May 1 A major under-the-hood refresh focused on speed, accuracy, and polish.

• Powered by the latest Ultralytics YOLO26 models — NMS-free, faster, and more accurate on small and distant objects
