It was developed during the H2020 project entitled OCARIoT (Smart childhood Obesity CARing solution using IoT potential) and is innovative in the sense that it allows efficient IoT data collection, integration of different commercial devices, improves the user's privacy, data's security and the management of data controllers respecting legal and ethics policies. The application acts as a token manager for accessing external services. Besides the main features of the application, we report the integration of Fitbit services, and the deployment in four Health IoT pilots in Brazil, Greece and Spain. A survey was conducted with users in these three pilots and collected information about their user experience. The results presented excellent feedbacks from the users, with initial needs of synchronizing different children's accounts and privacy, which justified the development of the tool. Finally, we got feedback of improvements in ethics, technological and reuse in Health IoT pilots.61085948enginfo:eu-repo/semantics/openAccessconference output10.1109/CBMS49503.2020.00084User experienceSpainGreeceBrazilFitbit servicesSmart childhood obesity caring solutionmHealth open source solutionOCARIoT Data Acquisition AppToken managerData controllersEfficient IoT data collectionIoT potentialHealth IoT pilotsUser experienceSpainGreeceBrazilFitbit servicesSmart childhood obesity caring solutionmHealth open source solutionOCARIoT Data Acquisition AppToken managerData controllersEfficient IoT data collectionIoT potentialHealth IoT pilotsAppHealth IoTMHealthPilotsRadiology, Nuclear Medicine and ImagingComputer Science ApplicationsSDG 3 - Good Health and Well-beingSDG 17 - Partnerships for the GoalsProject IDinfo:eu-repo/grantAgreement/EC/H2020/777082/EU/smart childhood Obesity CARing solution using IoT potential/OCARIoTinfo:eu-repo/grantAgreement/EC/H2020/777082/EU/smart childhood Obesity CARing solution using IoT potential/OCARIoTFunding InfoThe research has been performed under the OCARIoT project, funded from the European Union`s HORIZON 2020 Programme (2014-2020), ID 777082, and from the Brazilian Ministry of Science, Technology and Innovation through Rede Nacional de Ensino e Pesquisa (RNP), ID 003008.
