Overview

Overview

The Funf Library enables researchers and developers to easily and reliably collect and use data from Android devices.

Minimize impact on user

Probes built using Funf coordinate with each other to reduce power and processor usage, and minimize the effect on the device user.

Security

Care is taken to secure sensitive data. Applications on the device only have access to data that they already have permissions to access directly. Sensitive personal data, such as names, phone numbers, and texts messages, are one way hashed.

Remote Configuration

Many studies don't have direct access to the phones gathering data in the study. Funf will update its configuration periodically from a configured URL. In addition you can specifiy that data be uploaded to your server on a regular basis.

Extensibility

Developing custom probes is simple. New probes will automatically be integrated into the system and are configurable like built-in probes.

Reliability

Reliably persisting data to disk, and uploading it to a server can be inconsistent on mobile devices. Funf's data management services is robust in the face of unavailable SD cards and inconsistent network availability.
