Collect your REDCap data in an offline environment in the REDCap mobile app, and then sync your data back to your project on a REDCap server. REDCap is a web application, which requires the Internet to be used, but the REDCap mobile app allows for offline data collection for your REDCap projects. You can create your project in REDCap, securely download your project to the REDCap mobile app on your iPad or iPhone, collect data on the device (with or without an Internet connection), and then securely send your data back to your project on a REDCap server. Features • Multi-user interface with secure login that allows each user account to collect data for multiple REDCap projects in the app. • In addition to text and structured data, you can store and transmit photos, videos, signatures, and audio to REDCap. • When collecting data in the app from a participant, for security purposes you can easily restrict access to the rest of the app as they enter their data. • All user activity in the app is logged for audit purposes. The full logging history can be sent to your project on the REDCap server. Who is the REDCap Mobile App for? In order to use the REDCap Mobile App, REDCap must be installed on your institution’s server and must be at version 6.5.0 or higher. The REDCap Mobile App is designed to fit the following scenarios: • A REDCap project that needs data to be collected without any Internet access available. • A REDCap project that needs data to be collected with sporadic Internet access. If mobile devices are desired for use in REDCap data collection, and if WiFi or cellular Internet is amply available, then it is suggested to use the REDCap mobile web view that is available on the REDCap server, which provides real-time access to data. What is REDCap? REDCap is a mature, secure web application for building and managing online surveys and databases, and it is used by hundreds of thousands of users around the world (http://projectredcap.org). Before setting up a REDCap project in the app, you must already have a user account on a REDCap server hosted by a participating REDCap partner institution. If you belong to an institution that does not have REDCap, please visit http://projectredcap.org/participate.php to learn how to get REDCap where you are. What are some limitations of this app? The REDCap mobile app runs in conjunction with the REDCap web application software. You must already have a REDCap user account and project on a REDCap server before being able to download the project to the app. The app cannot function or stand independently without a REDCap server.

PLEASE BE ADVISED THAT THIS IS A LEGACY VERSION OF THE NIH TOOLBOX SYSTEM AND WILL BE RETIRED IN JUNE 2028. New users are strongly encouraged to download the NIH Toolbox V3 app instead of this legacy version: https://apps.apple.com/us/app/nih-toolbox-v3/id1627119550. Users whose studies end after June 2028 must plan to transition to the NIH Toolbox V3 app before then. The annual subscription cost of this app will increase each year through its retirement. *** Important Hardware Note: iPads (2018 and newer models) with 9.7- to 11-inch screens are recommended. Data collected on iPads with 12.9" screens has not yet been validated. *** NIH Toolbox® is a multidimensional set of performance and person-report measures that assess cognitive, emotional, motor, and sensory function in people ages 3-85, designed for research and clinical use. The original NIH Toolbox was developed by more than 250 scientists over 6 years, and sponsored by the 15 institutes of the National Institutes for Health that make up the NIH Neuroscience Blueprint. This update to the NIH Toolbox includes streamlined workflows and user interface for 50+ tests, for stand-alone use or as part of a complete assessment battery. With the NIH Toolbox app, researchers can assess function using a common metric and can “crosswalk” among measures, essential to the process of pooling data and often necessary when a large and diverse sample is needed. NIH Toolbox does not require a subscription for many features; however, a subscription is required to record assessment responses and to view and export results. Subscriptions are offered for purchase within the app for use on up to 10 iPads. Purchased subscriptions will automatically renew unless auto-renew is turned off at least 24 hours before the end of the current subscription period. Cancellation of the current (paid) subscription is subject to Apple’s discretion. Users can enjoy a free trial period to explore the NIH Toolbox app, but data will not be saved and results will not be generated during the free trial. The free trial period will be forfeited when the user purchases a subscription. Manage your subscription by going to your Apple Account Settings after purchase. All content needed to administer NIH Toolbox tests is available in the app, though some tests require additional hardware or materials. Please create a free account at www.NIHToolbox.org to access the Administration and Technical Manuals, supplemental materials, and list of publications. With the purchase of this app, you will immediately have access to tests in the Emotion, Motor, and Sensation domains. Tests in the Cognition domain require the successful completion of a separate approval on www.NIHToolbox.org. This approval process is included in the cost of the subscription; no additional purchase is necessary. Generally, approval will be granted to researchers and clinicians with the knowledge and training to use neuropsychological tests. Contact help@nihtoolbox.org for more details. Important information about the intended use and data security: * NIH Toolbox is not intended for use outside of research or clinical application. * Users control how data is managed. Data export via iCloud, email, and File Sharing can be enabled/disabled in the app. * If iCloud is enabled on your device, you may choose to upload data exports to a folder in iCloud Drive upon generation.
