CellReader

CellReader is an app to let you view information about your current cellular connection and other available connections.

With CellReader you can:

• See which band you're currently connected to.
• See the technology of the cellular network you're connected to.
• See all nearby towers reported by the modem.
• View information about your cellular registration status.
• And more.

There is also a Wear OS companion app, although its functionality is in early alpha.

Then, download the appropriate JAR from this repo and follow the instructions there for using it.

Error Reporting

CellReader uses Bugsnag for error reporting as of version 0.22. Previous versions use Firebase Crashlytics.
