The FCC Mobile Speed Test app is designed for iPhone users to evaluate their mobile broadband speeds and contribute to the Federal Communications Commission's National Broadband Map. This free utility provides three primary testing options: Challenge speed tests, Crowdsource speed tests, and QuickCheck speed tests. Each option serves a distinct purpose, from disputing coverage to evaluating mobile coverage accuracy across the United States.

Users can perform repeated tests for extended periods, set data caps to limit usage, and view their test history. Additionally, results can be exported as CSV files or emailed in ZIP format. The app prioritizes user privacy, allowing users to control data sharing while providing essential insights into their mobile connectivity.
