On-device pose estimation for fitness, rehab and workout apps
17 COCO keypoints stream directly on the phone or in the browser with no API key and no video upload.
An optional API key returns repetition counts, joint angles and a movement form score for exercises like squats and push-ups.
One engine with three integration paths: native React Native (Expo Go), browser JavaScript, and a WebView or iframe embed.
Ready-made back flexibility test, flexibility analysis with automatic angle detection, and pose comparison against a reference position.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
