## What is LagCheck?

Your internet may download movies at 500 Mbps yet stutter and freeze in the middle of a ranked firefight. LagCheck answers the one question that matters in seconds: is your connection route ready to play right now?

Download speed doesn't win games. What shapes your online match is UDP packet stability: average latency (ping), variation in milliseconds (jitter), and packets dropped along the way (packet loss).

LagCheck measures the route from your iPhone to gaming reference infrastructure by simulating real game traffic. No fake browser ping over HTTP or made-up scores.

WHAT MAKES LAGCHECK DIFFERENT?

• A Clear Verdict: No confusing charts or long explanations before a match. Get a clear, instant verdict: "Ready for Ranked", "I'd Avoid Ranked Right Now", or "Unstable Conditions".

• Real Route Testing Under Load: Measures idle conditions and simulates competing traffic at home to identify bufferbloat (when ping spikes because someone starts a video on your network).

• A Result for Your Squad: Share your measurement in a card for Discord and WhatsApp. Compare what was observed without attributing lag to the server or provider without evidence.

• Honest Diagnostics: See the stability observed and what changed under load, with guidance proportional to the result.

• Console and PC Mode: Measure the route from your iPhone and estimate how your console or computer may perform in the same room.

FULL TRANSPARENCY

• No intrusive ads blocking your test.

• No sign-up, no login, and no collection of personal data or browsing history.

• Deterministic measurement: if the network is too unstable for an accurate measurement, the result is inconclusive — never a misleading score.

• When available, CS2 includes the response time to a community reference in São Paulo. This is a complementary reading, not match ping or an official Valve integration.

Before you ready up for ranked, run LagCheck.
