The platforms below were built as instruments for the studies on this site and are used by other researchers. Each is described in a paper, which is the reference to cite.
Runs experiments built with lab.js as managed online studies, with hosting, participant management and data export, so researchers need no server of their own. As of August 2026, 308 researchers had run 291 studies with 15,355 participant enrolments.

Schedules and sends notifications for experience-sampling and diary studies to a free smartphone app for iOS and Android. Each notification links to an online survey or experiment. Schedules can be fixed, randomised, triggered by location or driven by real-time event data. Free for research and hosted at the University of Konstanz.
