This iOS application is part of the Beiwe research platform used to collect research-quality smartphone sensor and usage data from subjects in clinical and non-clinical research studies. Only participants who have been invited to join a study, and have been provided both a user ID and a password, can use this application. The Beiwe research platform, including this application, is a project of the Onnela Lab at Harvard University. This work is supported by funding from the U.S. National Institutes of Health.
