The Powerlifting Depth Checker app is designed for powerlifters and athletes seeking to improve their squat performance by accurately tracking depth and speed during repetitions. Utilizing a custom PDC SquatSync strap, users can secure their iPhone to the thigh, enabling precise measurements of squat depth. The application allows for the customization of depth angles, providing haptic or auditory feedback when the specified angle is exceeded.

In addition to real-time tracking, the app records sets and monitors changes in depth, eccentric, and concentric phases of squat repetitions over time. It is particularly beneficial for plyometric training, focusing on the integration of speed and strength. Future updates are planned to enhance functionality, including features like set cataloging, coaching modes, and progress graphics.
