Sency
An AI-tracking SDK that precisely captures movement and posture through a phone camera.
Sency is an AI motion-tracking SDK built for the fitness and rehab field that uses advanced on-device computer vision to precisely capture the body's joint angles, posture, and stability with just a phone camera. This technology's core advantage lies in its "on-device processing" characteristic — no need to upload images to the cloud, which not only greatly improves privacy security but also ensures smooth real-time feedback, letting users get guidance like having a professional coach beside them during home workouts or rehab training.
What it is and core capabilities
Sency is a development kit integrated into apps that can turn an ordinary smartphone into a high-precision motion analyzer. Through computer-vision algorithms, Sency can analyze a user's movement trajectory in real time and calculate precise joint angles and body symmetry. This means developers can easily bring "motion correction" features into their own fitness apps or telemedicine platforms, letting the system automatically detect whether squats, yoga, or rehab movements are standard and give real-time correction suggestions.
What problem it solves and who it's for
For fitness coaches, physiotherapists, or developers of digital-health platforms, the biggest pain point is being unable to ensure users' movement quality during remote training. Sency effectively solves the problems of "non-standard movements causing injury" or "poor training results." It's very suited to teams developing home-fitness apps, remote-rehab systems, and sports-science research software. Through Sency, developers can lower the development barrier and quickly build products with professional-grade motion-analysis capability, improving users' training experience and safety.
