Precise VBT and jump analysis. All on your iPhone. Arcus VBT brings velocity-based training and jump performance analysis together. Record live or import a video to measure performance, review technique and track progress—without an additional wearable sensor. PRECISE VBT. HARDWARE-GRADE ACCURACY AND RELIABILITY. Turn your iPhone into a VBT training tool. Analyze squats, bench presses, deadlifts, snatches, clean and jerks, and more. Track barbell movement with hardware-grade accuracy and reliability to monitor training intensity, understand fatigue and guide load selection. Explore mean and peak velocity, velocity loss, power and range of motion. Review joint angles, bar paths and movement phases to understand both individual reps and overall set performance. PRECISE JUMP ANALYSIS. MEASURE EVERY TAKEOFF. With proper technique, jump height measurements differ from force plate measurements by approximately 1 cm. Choose from five modes: CMJ (countermovement jump), CMJA (countermovement jump with arm swing), SJ (squat jump), DJ (drop jump) and POGO (repeated hops). Review jump height, takeoff velocity, flight time, contact time, time to takeoff, and RSI or RSI-mod where applicable. Explore individual jump replays, consistency, historical trends, same-day arm-swing gain and EUR comparisons. Supported modes also offer estimated peak power. Available metrics depend on the movement and required input data. LIVE VOICE FEEDBACK Choose announcements for velocity, power, rep count or velocity loss. Hear your performance during training and adjust your rhythm as you go. SYNCHRONIZED MOVEMENT AND DATA REPLAY Replay metric cards, velocity curves, joint angles and bar paths in sync with your movement. Rep intervals show the time between repetitions to help you review training rhythm. Supported deadlift variations also display a lower-back contour and curve to help review changes in torso posture. BUILD YOUR LVP. PERSONALIZE YOUR LOADS. Build a load–velocity profile from multiple sets. Personal OMVT calibration supports individualized 1RM estimates. Compare sets, reps and previous sessions to make more informed training decisions. TRACK PROGRESS. SHARE YOUR TRAINING. Explore training history and progress trends. Export videos with metric overlays and training posters, and sync records across devices. Separate Coach plans support athlete and training-record management.
