The app has three sections: Signal, speed, and history, indicated at the top of the screen. You can navigate through the sections by pressing the left and right arrow keys. Under ‘Signal’, your internet stability is measured in decibel milliwatts (dBm); if your number is closer to 0dBm, the better your connection is. ‘Speed’ tells you how fast data travels through your internet connection, upload and download speeds. ‘History’ shows the recent speed tests you’ve run and their results.
