experience sampling made easy

Try mobileQ


mobileQ is a free, open-source web dashboard and Android smartphone application developed by the research group of quantitative psychology and individual differences at KU Leuven to enable researchers to perform experience sampling or ecological momentary assessment (ESM/EMA) studies and interventions in an easy, intuitive, and accessible way.


Design your own ESM/EMA study with an easy-to-use web interface.


Collect data while you track the compliance and progress online.

Response formats

Make use of survey items with different commonly used response formats.

Beep scheduling

Flexible fixed or random interval beep scheduling.

Data download

Data can be downloaded in an accessible format (csv, xlsx, ods).


Timestamps and response times of the responses are recorded.

(No) internet access

With internet access, incoming data can be continuously transferred and monitored online, but no internet connection is required.

Academic use only

You are only allowed to use the software and service for academic research purposes.


The software is only tested on the phones our research group is using. Please check the list of compatible devices before using mobileQ.


As mobileQ is a free, open-source project, there is no active helpdesk. To help you get started we will be providing the following resources:

Instructional videos

If you want to find out how mobileQ works, please take a look at the instructional movies that show you step-by-step how to set up a project, surveys, beeping schedules, participants, etc.


The mobileQ paper is accepted by Behavior Research Methods and can currently be found at PsyArXiv.

You can use the forum to ask or answer questions of other mobileQ users. This is a community driven forum. You will not find the mobileQ developers here frequently.


mobileQ as a service

You can use mobileQ remotely. This option allows you to use mobileQ and all its features immediately, and doesn't require you to have access to any server resources. Your data is securely stored on KU Leuven servers, to which you have access at all times. You remain the owner of the data, and KU Leuven does not hold any claim over it, but only offers its server space to collect data for your studies. For this option, you only have to install the app on smartphones, register and get started. This option is advised when you want to run ESM/EMA studies, but don't need to have your data stored immediately on your own server.

mobileQ hosted locally

You can use mobileQ locally. This option allows you to download all the mobileQ software yourself, and install it on your own servers. All data you collect will be immediately stored on your own server, rather than our KU Leuven server. This option is advised when you want to have the data directly collected on a local server. This option requires technical knowledge needed to install mobileQ on your own server.
