What does Lagcheck measure?
The app measures response time, jitter, packet loss, and behavior under load with UDP packets. The website provides an HTTPS estimate of response, jitter, and added delay under load; packet loss requires the iPhone app.

Official support center
Lagcheck is available for iPhone (iOS 17+). Our team can help with the test, diagnosis, and verdicts.
Does it test my next match server?
No. Lagcheck measures a regional reference route and the health of your connection. It does not access private game infrastructure or invent measurements.
What should I do after an unstable verdict?
Avoid ranked for now, move closer to the Wi-Fi router, check for downloads on the network, and restart the modem if the instability continues.
