Metric - Barbell Tracker, from Core Advantage Athletic Development, is a velocity-based training app that turns a smartphone camera into a gym-grade tracking tool for barbell sessions. It uses computer vision and machine learning to deliver real-time bar speed, peak power, and range-of-motion metrics per rep, removing the need for external sensors. The app also includes automatic bar path detection, fatigue monitoring, and video overlays. Powerlifters, Olympic lifters, and coaches gain portable feedback to guide training intensity and fatigue management.

Metric converts a phone camera into a reproducible bar speed and power meter

Metric measures mean velocity, peak velocity, and peak power for every rep, and estimates one-rep max from the load-velocity profile. Because the tool analyzes barbell movement through the device camera using computer vision and machine learning, users get rep-level metrics without attaching wearables. Those numbers can inform set-to-set intensity and help track progress over weeks using the app's logging functions.

It works without external hardware but needs a stable setup

The app removes external sensors by relying on the phone camera, yet the developer recommends a tripod or stable mount to keep the camera still for accurate tracking. Metric recognizes standard Olympic barbells and common plate types, and it performs best on devices with modern camera systems. Clear visibility of the bar end improves detection, so positioning and lighting are practical setup considerations before a session.

Designed for coaching workflows and post-set technical review

Metric combines live metrics with video recording and on-screen overlays to support technical feedback and review. The app logs workouts and tracks progress over time, and it includes velocity loss thresholds for fatigue monitoring to prevent excessive intensity drift. Because the product was developed by athletic coaches, its interface and outputs align with common strength-coaching practices, enabling coaches and serious lifters to review technique alongside objective numbers.

Expect device and account limits when using advanced functions

The app processes camera footage with machine learning, so device capability affects responsiveness and tracking consistency. Advanced analytics and long-term data storage are available through an account-gated tier, which changes how much historical data and analysis are kept inside the app. Users should plan for local video files and metric exports when they want session archives for deeper review.

Metric suits data-driven lifters who accept device-dependent limits

Metric is a practical option for strength athletes and coaches who want to introduce repeatable, rep-level measurement into everyday barbell routines. Accuracy depends on a steady camera position and a capable phone camera, which can limit consistency on older devices. For users ready to set up a reliable mount and use an account-gated tier for deeper history, the app fits into regular training as a measurable check on intensity and fatigue.
