The EMS Mobile STUDIO app is the control platform for the EMS Mobile STUDIO hardware. It was specifically developed for commercial use in EMS personal and group training. The Studio app enables individual one-on-one and group training sessions with up to ten participants simultaneously. A particularly practical feature is that participants can train either synchronously or with individual settings. Different frequency ranges and intervals can be flexibly combined, allowing training to be optimally adapted to the specific needs of each client.
