Digital technologies are transforming traditional learning methods into new paradigms such as blended learning and E-learning. Influenced by Covid-19, companies have rapidly developed EdTech solutions to help educational institutions improve and modernize their learning processes. However, many of these companies face challenges in evaluating user experience across different markets using usability testing methods. To address this gap in the literature, a consortium from the Horizon Europe project EdTech Talents began developing a Usability Platform Test to assist EdTech companies. This study presents an experimental test of one EdTech company conducted with a group of students from an Austrian university. The main results identify dimensions essential for usability testing, particularly for EdTech companies. Additionally, the results visualize user feedback, demonstrating how comments can help EdTech companies enhance their apps to reach new markets.
