## What is Mesmerise?

Mesmerise is an experience sampling method (ESM) companion app that allows its users to join a variety of academic studies and respond to the surveys configured by the researchers.

As the participant of a study and user of Mesmerise, you will be able to customise your notification schedule preferences. Together with the notification schedules set out by the researchers, this will create a pattern that works for you and complies with the study requirements.

By signing up for a Mesmerise account, you will be able to participate in a number of studies under a single account, without having to re-register or provide new e-mail address. At the same time, your participant identifier will be kept separate from your user account, allowing for a certain level of privacy between the studies.
