julian Julian Wehlmann
MSc Psychology in Sport and Exercise, German Sport University:

It is very intuitive and even I with little programming knowledge can learn easily and quickly. I recently told my professor that I could imagine using this for my future doctorate. A really good website!

durham Tuomas Eerola
Professor of Music Cogntion, Durham University (UK):

One of my PhD students recommended PsyToolkit for our online studies four years ago and now we have done over ten studies with it. These have ranged from priming (with reaction time responses) studies to generic surveys to customised setups where we pioneered new paradigms such as visually guided continuous ratings. In our review of all online platforms (Eerola et al., 2021), PsyToolkit offers best value and flexibility, and it also provides robust solutions to issues of quality control and security (GDPR etc.). The documentation is easy to use and comprehensive.

gary Gary Fisk
Professor of Psychology, Georgia Southwestern State University (US):

Try PsyToolkit. It was very useful for collecting data during the socially-distant pandemic conditions.

michal Michał Folwarczny
PhD in Marketing, Department of Business Administration, Reykjavik University:

I started using PsyToolkit at the beginning of my PhD. At that time, I had no programming knowledge. However, after watching a tutorial on YouTube, I designed my first experiment and ran it online after only two or three hours. PsyToolkit has always been very intuitive, easy to learn, and most importantly, free. It is also very easy to share study scripts on repositories like OSF; therefore, PsyToolkit contributes to open science.
