About

USpeedtest for the web. Measures against Cloudflare's speed servers with parallel, time-based download and upload legs, idle and loaded latency, and Cloudflare's own ping definition. Results are kept in this browser without your IP address, and sent to uspeed.app only while saving is on above. Each Standard test moves roughly 1–3 GB on a fast link.

Get USpeedtest for Android — the same test, plus the radio details a browser cannot see: carrier, 5G band, signal and Wi-Fi link rate.
