iWareBatik is two digital tools (a website and a mobile app) designed and developed to communicate the value of Indonesian Batik, a UNESCO intangible cultural heritage in 2009. Such tools have been evaluated through a panel of 997 bachelor students recruited in 33 Indonesian universities. They have been involved in a process that encompassed user testing activities, filling in a survey related to them, participating in a focus group, and writing a short essay. 156 of them later on took part in hackathon type of competition, aimed at suggesting possible improvements to the iWareBatik set of tools. This paper outlines the overall design of the evaluation activities, and presents in detail the results of the user testing and the related survey, highlighting positive elements and dimensions to be improved. Such evaluation exercise is not only for the set of digital tools at stake, but can provide a relevant model for all those projects aiming at using digital media in the field of intangible cultural heritage, helping to fill-in the gap between design, development, and evaluation.
