The CheerpJ technology has been a true game-changer for PhET simulations. For years, as school technologies have shifted to Chromebooks and iPads, many teachers and students lost access to some of their favorite PhET simulations because these simulations were built on our legacy Java code. With CheerpJ, we were able to create new browser-compatible versions of 57 legacy Java simulations, restoring access at a time of great need. The PhET teacher community could not be happier!
