A blazing-fast network diagnostics toolkit for iPhone and iPad. Every tool a pro admin needs — ping, traceroute, DNS, whois, port checks, ASN lookup, LAN scan — in one app. No accounts. No ads. No telemetry.
Built for admins who need answers, fast. Tap a tool, get the data. No tutorials. No nags. No empty states.
Interface, IP, subnet, gateway, DNS, public IP, ASN, ISP, geo — at a glance. Auto-refresh on network change.
getifaddrs · ipify · bgpviewA, AAAA, MX, TXT, NS, CNAME, SOA, PTR. DNS-over-HTTPS by default — bypasses captive portals.
DoH · Cloudflare · Google · CustomTCP-based traceroute on port 80 or 443. Works through firewalls that drop ICMP. Hop-by-hop RTT with reverse DNS.
TCP · IPv4 / IPv6ICMP echo with packet loss, min/avg/max/stddev. Live graph as packets arrive.
ICMP · IPv4 / IPv6Domain whois with full referral chain. IP whois via RIR. Clean, parsed, copyable.
TCP/43 · RIR chainSingle port or list. Banner grab where available. Customizable timeouts. Fast parallel checks.
TCP · Banner grabHEAD/GET with status, headers, response time. TLS certificate inspection — issuer, validity, SAN.
HTTPS · TLS certSubnet sweep with ICMP plus Bonjour enrichment. Hostnames via reverse DNS. Service hints where broadcast.
ICMP sweep · mDNSSwiftUI throughout. Network.framework where possible. Real ICMP via datagram sockets. No Electron, no React Native, no compromises.
Dashboard updates instantly when you switch Wi-Fi, plug in Ethernet, or jump on cellular.
Every tool works on IPv4 and IPv6. NAT64, captive portals, DNS64 — all handled.
Save targets you check often. Replay past tests. Copy and share any result.
Split-view, multitasking, keyboard shortcuts. Built for the way pros actually work.
Other "free" network apps gate features behind subscriptions, plaster ads on results, or harvest your telemetry. TachySense doesn't.
No paywalls, no tiers, no premium features. Every tool, every time.
Zero. Not a single thing to unlock. Use it all from day one.
No banners. No interstitials. No "watch a video to continue".
No analytics SDK, no telemetry, no third parties. We don't even know you launched it.
Local network scanning, ping, traceroute, port checks — all execute on your device. Nothing leaves.
ASN, geo, and whois data come from public APIs queried without authentication. No account links your queries.
TachySense has no cloud component. There's nothing to breach because there's nothing stored.
TachySense is a free, open utility from Nexilon. Coming to the App Store in summer 2026. TestFlight beta opens earlier — drop a line if you want in.
