Your network,
on radar.
NetRadar turns your iPhone into a complete network security kit — see every device on your Wi-Fi, get alerted when a stranger joins, test your speed, and run pro-grade tools. Scans run on your iPhone and stay there.
One app, the whole toolkit
Simple enough for anyone, powerful enough for IT pros.
Investigate Any Device
Tap any device for a full report — ping, open ports, DNS, WHOIS and history, together in one place.
Who's On My WiFi
List every connected device by name, IP, MAC and vendor. Get an instant alert when a new or unknown device joins.
WiFi Security Score
A live security score with clear, fixable findings — risky open ports, weak TLS, and exposed services in plain English.
Speed Test
Test your real download / upload speed and latency in one tap. Find out if you're getting the internet you pay for.
Ping & Latency
Continuous ping with a live graph — min / avg / max, packet loss %, jitter, p95 / p99, and a VoIP call-quality (MOS) estimate.
Traceroute
Hop-by-hop route mapping with per-hop latency and reverse DNS — see exactly where slowdowns and routing problems start.
Port Scanner + CVE
Fast TCP port scanning with service and version detection, cross-referenced against known CVEs (authorized testing only).
DNS Toolkit
A/AAAA/MX/TXT/NS/CNAME/SOA/SRV/PTR lookups. Compare resolvers side-by-side to catch poisoning or stale records.
Pro Security Tools
TLS / cipher inspector, HTTP security-header recon, WHOIS / ASN lookup, SNMP checks and Wake-on-LAN.
Private by design
NetRadar is a network tool, so it makes the connections you ask it to — the pings, scans, lookups and speed tests you run, sent to the targets you choose. There are no accounts, no ads and no tracking, and your scan results never leave your device. The only thing sent to the developer is optional anonymous usage — app steps under a random ID, never your IP addresses, devices or Wi-Fi name — and you can turn it off in Guardian › Privacy.
NetRadar is for diagnosing and securing networks you own or are authorized to test. Please use NetRadar responsibly.
