ISpeedy Internet Test

iSpeedy is a convenient internet speed utility for checking and comparing your connection over time. Run clear, live download and upload tests using Measurement Lab's NDT7 network test.

Watch your speed change in real time, then explore the results: latency, loaded latency, connection details, and an estimated stability score. Completed tests stay in a local history so you can revisit and compare results across dates and connections.

Keep custom iSpeedy widgets on your Home Screen or Lock Screen for one-tap access to a new test, right where you need it. You can also start a test from the app or an available Control Center control. Switch between light and dark appearance to suit your setup.

Tests connect to Measurement Lab. Starting a test shares your public IP address and measurement data with M-Lab, which may publish test data under its own privacy policy. iSpeedy's stability score is an estimate based on speed samples, not a separate network diagnostic.
