REDCap Mobile App for iOS and Android

The REDCap mobile app is an app that can be installed on a tablet or mobile device so that data may then be collected in an offline fashion on that device, after which it may then be synced back to this project on the REDCap server. The app is most useful when data collection will be performed where there is no internet service (e.g., no WiFi or cellular service) or where there is unreliable internet service. Once a user is given 'REDCap Mobile App' privileges in a project, they can navigate to the mobile app page on the left-hand menu and set up the project inside the mobile app on their device. Once the mobile project is set up on the device, the user can collect data (which is stored locally on the device), and then at some point sync that data back to their project on the REDCap server.

• Before users can use the mobile app for a project, they must first be given "Mobile App" user privileges, after which they will be able to see the "REDCap Mobile App" link on the project's left-hand menu and then be able to access that page, which will provide links to download the Android and iOS app and instructions for initializing that project in the app on their mobile device. Note: When a user creates a new project, they will automatically be given "Mobile App" privileges by default.

• There is an additional user privilege "Allow user to download data for all records to the app?" that specifically governs whether or not the user is allowed to download records from the server to the app. This may be done to prevent users from unwittingly (or wittingly) downloading lots of sensitive data to their mobile device. If a user is given this privilege, then when they initialize the project in the app and the project contains at least one record, then the app will prompt the user to choose if they wish to download all the records to the app or not.

• Syncing data back to the REDCap server: When the user has collected some data in the app and now wishes to send the data back to the server, they will go to the "Send data to server" page in the app. If there are any possible issues that might arise when sending the data to the server, the app will prompt the user to make a decision before sending the data. For instance, if the project uses record auto-numbering, and a record already exists on the server with the same record name, then it will let the user know that it will rename the record accordingly during the sync process in order to prevent any overwriting of the record already on the server. There are many different scenarios that can occur in which a user might be prompted to make a decision, and the app is fully capable of providing the user with just the right amount of guidance so that they feel confident sending their data to the server with no issues.

• Remote lockout: If a user sets up a REDCap project on the mobile app, and then another user revokes their "REDCap Mobile App" user privileges on the User Rights page in that project, then it will prevent them from accessing it on their mobile device by locking them out of that particular project. In this way, you may perform "remote lockout" to further protect data stored on mobile devices. Additionally, a user can revoke/delete their API token for the project, which will also cause a remote lockout, although the lockout will be permanent and will cause all data currently stored in the app to be lost.
