MulitKAT is a feature in beta that allows up to three KATs to be used sumultaneously from a single mobile device. It is not yet supported on all devices.
However, given the brain's limited capacity to process and act on mulitple streams of informaiton, no more than 2 Kats delivering feedback ao the body is suggested. Others movement educators have used up 2 KATs to teach sequence or timing, and a used a third KAT with feedback off for data collection purposes, to see what happens to the shoulder when the athlete focuses on the hips, or feet or other similar use case.
