Metric is an advanced workout tracking app that combines traditional logging with velocity-based training. It uses your phone's camera to measure barbell speed, providing insights into fatigue, recovery, and progression without requiring expensive external hardware.
The app utilizes your iPhone or iPad's camera to record your lifts. It then analyzes the video to generate precise, validated measurements of bar speed for over 60 exercises. This allows you to monitor fatigue through velocity loss during sets and receive audio cues for specific velocity targets.
