Video-Performance Sync -- Connect to our app with our powerful and lightweight Bluetooth Performance Clip. Using advanced motion algorithms, the PDC app automatically detects repetitions and lift phases, displaying a detailed waveform of your movement that syncs automatically with recorded videos seconds after completing your exercise (video recording is optional). Post-Set Metrics -- Receive, concise reports that compare the current set's performance with your all-time best at that weight/rep range. Compare weight lifted, rep speed, range of motion, tempo consistency, and pause duration with the previous set, then receive weight and rep recommendations for next next set. Detects set trends and technique breakdown from rep to rep. Improve Technique -- The app’s side-by-side video comparison and velocity slider tool make it easy to pinpoint technical breakdown, isolate lift phases, and identify sticking points for targeted improvement. Built for Powerlifters and Coaches -- Set custom depth or height targets, and receive audio cues mid-set when you hit or pass them. After training, instantly assess whether each rep meets competition standards—including depth, range of motion, and downward motion. Store all of your sets and exercises on our app, included with thumbnails and sorted by date, weight, reps, or difficulty (10 minutes of free video storage included). Performance Clip -- Our Bluetooth Performance Clip attaches to your arm or leg with our PDC bands (4 attachment bands XS-XXL included) and transmits real-time data directly to the free PDC app. The clip has a range of up to 50m and is rechargeable with 8 hours of battery life. Why PDC Stands Out -- PDC combines the affordability of consumer devices with the depth and accuracy of professional-grade tools. It’s visual, intuitive, and powerful, designed to make performance analysis accessible to everyone—from recreational lifters to elite competitors. Our small yet dedicated team is continuously refining PDC with user feedback so it can become a staple performance tracking solution for powerlifters and performance athletes worldwide.
