Latency Labs

Latency turns your iPhone into a real network instrument. Pick any host or IP and watch your connection come alive on a full-screen map — from the router in your living room to servers all over the globe.

Is it down, or is it just you? Latency answers in seconds.

PING ANYTHING • ICMP ping with live round-trip charts, jitter, loss, and per-ping logs • Continuous sessions with configurable count, delay, timeout, and packet size • Feel it work — haptic feedback on timeouts, starts, and finishes

TRACE EVERY HOP • Traceroute drawn live on the map, hop by hop, mapping your path • See exactly what route your packets are taking to their destination

REACHABILITY CHECKS • One tap runs a diagnosis: network, DNS, ICMP, port 443, and a real HTTPS response • Slow server? Blocked port? Filtered ICMP? Get a clear verdict, not a shrug

LATENCY INTELLIGENCE • Geolocate targets and every traceroute hop on the map • See who actually runs the host — network operator (ASN) at a glance • Trending incidents for major services, and issue reporting

BUILT FOR iOS • A home and lock screen widget that keeps an eye on your favorite target • Bookmarks, history, and search that resolves as you type • No account. No sign-in. Completely Free.

Whether you're a developer chasing a flaky API, a gamer hunting lag, or the family's unofficial IT department — Latency shows what your connection is really doing and where.
