Prior to subscribing, you may explore the NIH Toolbox V3 app via the Limited Free Trial. The Limited Free Trial allows access to the tests, batteries, participants, and test administration. This will give you the opportunity to get comfortable using the NIH Toolbox V3 app and explore what it has to offer. However, while using the Limited Free Trial, no data will be saved and you will not have access to the reports or data exports. To begin collecting data, you must first subscribe to the app. To view tests in the Cognition domain, you must first enter a Cognition access code, which users can request for free at NIHToolbox.org.
