This report presents the key insights and findings from a Comparative review of the First Aid App funded by the Global Disaster Preparedness Center (GDPC). The study was led by Trilateral Research (TRI), with support from Fraunhofer Institute for Open Communication Systems (FOKUS), Utah State University (USU) and the Asian Disaster Preparedness Centre (ADPC). The project began in September 2015, with the aim of understanding the impact of the host organization, i.e., the National Society, on the rollout and uptake of the First Aid App, developed under the Universal App Program. The key insights and recommendations provided in the report are designed to support the GDPC and National Societies in developing, rolling out and marketing the First Aid App in the future.
