Release Notes
We're continuously improving features and performance, fixing bugs, and releasing updated content to Lt.
May 13th 2026
ContentWe are thrilled to announce a major expansion and refresh of our Sensor Collections! This release includes the introduction of three new Sensor Collections – Neuroscience, Pharmacology, and Psychophysiology – alongside 18 brand-new labs. With the release of the PowerLab T1, our content now features stimulation activities and the ability to author your stimulation settings directly within Lt.app. Across our Background Lessons, Pre-Lab Preps, and Labs, we have rebranded our content to “Sensors” and integrated new artwork and audio descriptions for videos. Additionally, we have implemented various bug fixes and technical improvements to ensure better accessibility and clarity for an improved learning and teaching experience.

ContentNew Collection
The sensors Exercise Physiology collection is here!
We've recently released the Sensors version of the Exercise Physiology collection! This new collection is part of the physiology content pack. The latest version of the Spirometer sensor (SEN2092) is specifically recommended over the older Spirometer sensor (LTS2090) for these lessons, as they involve extended or long-term physiological data acquisition. This is because its design provides enhanced stability and accuracy over longer recording periods.
