SocialCapitalCompanion (SCC) is an App that lets users keep a diary about their own personal network.


A paper describing the SCC has been presented at the ASNA 2013. 27-30 August, 2013.

A presentation of the SCC has been given at the International Seminar into Personal Networks. 3-5 July, 2013.


A preview version of the SCC is designed for smartphones and tablet computers running Android 4.0 or newer. Note that this version is "unstable" and subject to frequent updates (also see the disclaimer and conditions of use).

Note: to be able to install the SCC on your Android phone or tablet you have to open the settings, go to security, and allow the installation of non-market apps or apps from unknown sources (the precise naming of this option depends on your device).

Download the file SCC-Preview.apk to your Android device and install it.
