About Us

James Flynn started Extrasensory Devices in 2011 by building the Backbeater Tempo Monitoring System for drummers. ESD prioritizes hardware quality, and app science, for the working professional or prosumer.

Since 2011 Extrasensory Devices has developed several other products and completed four successful Kickstarter campaigns. Combined, these campaigns have delivered over 10,000 units to happy customers.

Since our start in 2011 we have received some great press. Here are just a few examples:
