About this app

Qdot is an app specifically designed to collect data for scientific studies through questionnaires. The questionnaires can be presented either using the ESM (EMA) method or simply at a given timepoint (or time range). The app is suitable to conduct diary studies and it has been designed to facilitate multiple studies simultaneously. The app can be adapted to your needs, e.g. it can show your study logo. Qdot has been developed and is managed by Maastricht University, but is also suitable to use in other scientific settings, outside Maastricht University.
