Shadow Internet Speed Test

Most speed tests give you one quick number. Shadow runs the full experiment. Shadow Internet Speed Test measures your connection the way an engineer would: three independent 11-second passes in each direction, on fresh connections, with the TCP ramp-up discarded — then reports the median. One unlucky (or lucky) run never decides your result, and a consistency score tells you exactly how stable your connection was. ACCURACY FIRST • 3 full download passes + 3 full upload passes, median reported • Multiple parallel streams saturate the line the whole time • First 2 seconds of every pass excluded (TCP ramp-up) • 12-sample ping with real jitter measurement • Consistency score (±%) so you know how trustworthy the result is • Tests run against Cloudflare's global edge network SLEEK & FOCUSED • Beautiful dark interface with a live speedometer • Deterministic progress bar and countdown — it never jumps around • Wi-Fi or Cellular, ISP and test-server info at a glance • Full test history saved on your device PRIVATE BY DESIGN • No ads. No trackers. No analytics. • Your results never leave your phone. FREE & PREMIUM Run one full free test every day.
