クアトロDNS ネットテスト

QuattroDNS finds what's actually wrong with your internet—not just how "fast" it is. Speed tests tell you megabits. They don't tell you why your game lags, your call drops, or your stream buffers. QuattroDNS measures the things that actually cause those problems: ping, jitter, latency spikes, and real packet loss. Run a test in 30 seconds and get a clear stability score plus plain-language guidance on what it means and what to do about it. WHAT IT MEASURES • Ping (latency) — how responsive your connection is • Jitter — how steady that latency stays • Packet loss — data that never arrives, the real cause of lag • Latency spikes — sudden stalls that ruin calls and games • Stability score — one simple 0–100 health number WHY QuattroDNS • Real diagnostics, not just a speed number — built for gamers, remote workers, and streamers • Quick Test in 30 seconds, or a detailed Deep Test scan • Test popular targets (Cloudflare, Google, Apple, YouTube) or add your own host • Clean history so you can spot patterns over time • Light & dark themes, full Dynamic Type support • No account, no personal data, works fully offline HOW IT WORKS Pick a target, choose Quick or Deep, and tap Start. QuattroDNS pings the target repeatedly, tracks every response, and turns the raw numbers into an easy score with advice you can act on. FREE & PRO Run up to 2 checks a day for free. QuattroDNS Pro is a one-time purchase that unlocks unlimited checks and removes ads—no subscription, yours for good. The free version shows ads from third-party ad networks; those ads don't use the advertising identifier and don't track you across apps. PRIVACY FIRST No sign-up. We never collect your name, email, or location—only an anonymous installation ID and the diagnostics you run. No advertising identifier, no cross-app tracking. Your history stays on your device, and you can clear it anytime.
