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.

Please note, continued use of GPS running in the background can dramatically decrease battery life.

The Beiwe2 app connects to any Beiwe server deployment; during registration, you can specify the URL of the Beiwe server. This is unlike the Beiwe app, which is preset to connect to studies.beiwe.org.

Beiwe integrates with the Health app, because Beiwe's surveys are built on ResearchKit, which uses HealthKit as a dependency.
