The Screenwise Meter mobile app, developed by Google LLC, is a market research panel management app. It is exclusively designed for registered panelists who participate in market research panels. The app cannot function for those who are not registered.

The app manages panelists' participation in market research panels, which is part of Google's Panel Research program. The program helps to gather information about technology usage, media consumption, and how people use Google products. The app works in sync with external Screenwise measurement devices.

The app requires certain permissions to function, including Contacts (Get Accounts) to allow for Google account login and detect Google accounts configured on the device. It also needs Location to locate and configure external Screenwise measurement devices and Bluetooth to locate and configure external Screenwise measurement devices. Additionally, it requires Accessibility to collect text on the screen, input from text entry, taps, swipes, and web browsing history.

Overall, the Screenwise Meter app is an essential tool for registered panelists to manage their participation in market research panels.
