Train Reactive Intelligence. The A-Champs app is the control layer of Professional Cognitive-Motor Training. Coaches, physiotherapists, neuro-athletic specialists, clubs and facilities use it to train how athletes perceive, decide and move under changing conditions. You define the goal. You design the task. You coach the movement. The app runs the system and returns the results. START IN SECONDS Choose from 400+ ready-to-use exercises for performance, neuro-athletic, rehabilitation, education and group settings. Adjust the task, save your preset and train. DESIGN YOUR OWN TASK Build custom exercises from our open training programs. Set the visual, auditory and tactile cues, the timing and the rules. Combine exercises into complete sessions with breaks and loops. ADVANCED CONTROL FOR ROXPROX LASER Set the laser-beam sensing distance from 10 to 150 cm (4 to 59 in), brightness and blink speed, and show letters, numbers and symbols on the LED matrix. Athletes move through the cue instead of stopping to tap it. RUN A WHOLE FACILITY Create up to 4 independent ROX groups and run several stations at the same time. Works with ROXProX Laser, ROX Touch and CogniCage. MEASURE. REVIEW. PROGRESS. See results as soon as a drill ends. Every completed exercise is saved, so you can compare sessions and plan the next progression with objective task data. ALSO RUNS GOAL STATION The same app runs Goal Station football training environments by A-Champs, including Rebounders and Arena setups. One login, one workflow, from the gym to the pitch. PROFESSIONAL TRAINING. NO MANDATORY SUBSCRIPTION. Everything you need for day-to-day training is included with your A-Champs system: the exercise library, your own exercises, session building and results.
