WRAP – Simple Data Collection for Study Participants

What is WRAP?

WRAP is a free Android application created by RTI International to help participants in research studies collect and submit data directly from their mobile devices. The app is designed to be straightforward, allowing users to focus on providing the information researchers need without dealing with complex setup steps.

Main Features

• Guided data entry – The app presents clear prompts that match the study’s questionnaire or data‑capture requirements.
• Secure local storage – Information entered on the device is kept locally until it can be transmitted according to the study’s schedule.
• Background syncing – When an internet connection is available, WRAP can upload collected data automatically.
• Minimal permissions – The app requests only the permissions necessary for its core functions, such as network access for data upload.

How It Works

After installing WRAP, participants receive a setup code or link from the study team. The app uses this information to configure the appropriate questionnaire and data‑submission schedule. Users then open the app, answer the prompted questions, and tap a button to save or send their responses. The interface is designed for clarity, with large touch targets and concise instructions.

Practical Uses

WRAP is useful in any research setting that requires regular or one‑time data input from participants, such as:

• Health surveys tracking symptoms or medication adherence.
• Behavioral studies collecting daily activity logs.
• Environmental research where participants record observations.

Installation Information

The app can be downloaded from the Google Play Store. Search for "WRAP" and look for the developer name "RTI International" to ensure you are installing the correct version. The installation process follows the standard Android flow: tap Install, grant any requested permissions, and open the app.

Compatibility

WRAP runs on Android devices that meet the minimum operating system requirements defined by the Google Play Store. Because the app does not rely on advanced hardware features, it works on a wide range of smartphones and tablets.

Things to Know Before Installing

• Make sure you have a stable internet connection for the initial setup and for data syncing.
• Keep the app updated through the Play Store to receive any improvements or bug fixes.
• If you encounter issues, contact the study coordinator; they can provide a specific support channel.

Who May Find It Useful?

Anyone enrolled in a research study that uses mobile data collection will benefit from WRAP. The app is especially helpful for participants who prefer a simple, guided interface over paper forms or more complex survey platforms.

Frequently Asked Questions

Do I need an account to use WRAP?

No separate account is required. Access is granted through a study‑specific code or link provided by the research team.

Is my data private?

WRAP stores data locally until it is transmitted over an encrypted connection to the study’s server. The app only accesses the permissions needed for its core functions.

Can I use WRAP offline?

Yes. Data can be entered without an internet connection and will be uploaded automatically once connectivity is restored.

What should I do if the app crashes?

Restart the app and ensure you have the latest version installed. If the problem persists, reach out to the study’s support contact.
