IP Scanner & Service Watcher vs Subnet Scout

IP Scanner & Service Watcher is a field toolkit for IT support engineers, network administrators, CCTV/camera technicians, and home lab users. Diagnose the network you are connected to, discover LAN devices, check open ports, inspect TLS certificates, resolve DNS, run ping/traceroute, and watch important services from your phone. KEY FEATURES - LAN discovery: scan the current subnet or a custom CIDR/IP range and review device IP, MAC, vendor, online/offline state, and open-port status. - Port scanning: use focused profiles for IT, servers, network devices, and CCTV systems, or enter custom ports and ranges. - Multi-instance tasks: run ping, LAN port checks, WAN checks, traceroute, and loop scans side by side, then jump back to each live task from the running-task badge. - WAN visibility: detect public IPv4/IPv6 and check public port reachability through an external probe. - Network tools: Ping, DNS Lookup, Traceroute, Website Check, Site Alive, Endpoint Health, Content Match, SSL/TLS Check, Domain Expiry, Subnet Calculator, Wake-on-LAN, and MAC vendor lookup. - Service Watchers: convert supported tool runs into recurring checks with healthy/failing/recovered states, thresholds, cooldowns, history, and optional notifications. - Clear diagnostics: TLS, HTTP, DNS, TCP, IPv6, and OS-level limitations are reported clearly so field work does not stop at a vague network error. The app is designed for networks and systems you own or are authorized to test. It is not a nearby Wi-Fi/SSID scanner, Wi-Fi analyzer, wardriving tool, VPN, proxy, or broad internet scanner. No account is required for the core scanning tools.

Subnet Scout helps you discover devices and services on the local IPv4 network connected to your iPhone or iPad. Choose or enter an IPv4 CIDR range, start a scan, and watch results appear as the app combines ICMP echo, targeted checks of common TCP ports, and Bonjour service discovery. Features: • Detects the active Wi-Fi IPv4 range • Finds reachable devices with evidence from ICMP, TCP, and Bonjour • Shows hostnames, common open TCP ports, and advertised Bonjour services • Displays service type, hostname, port, addresses, and selected TXT metadata • Searches by IP address, hostname, port, or service • Adapts from iPhone navigation to an iPad split-view interface • Keeps scan results on your device Subnet Scout uses only public iOS and iPadOS APIs. iOS does not expose the system neighbor table to apps, so MAC addresses and vendor lookup are unavailable. Bonjour discovery is limited to service types declared by this app version. Local Network permission is required to scan. Results can vary because of device sleep, firewalls, client isolation, VPN routing, and segmented networks.
